== Remove "is a list of: person" from items with "instance of: Wikimedia disambiguation page"? ==

Hi,<br/>
I noticed a lot (actually ~42.000) items are tagged with both {{P|360}}={{Q|215627}} and {{P|31}}={{Q|4167410}}. Now the property docu for P360 says about the domain:<br/>
"Domain: items with interwikis to (en) pages named "List of" etc."

So should {{P|360}} be reserved for real lists only? Then a bot should probably delete all those {{P|360}}={{Q|215627}} from items with {{P|31}}={{Q|4167410}} (though to be sure the bot also needs to exclude items where the label contains "List" as there seem to be a few items with wrong tags). On the other hand it might be useful to know that a disambiguation page is about a person (not sure for what though). --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:35, 23 June 2014 (UTC)
* Ok, but what property will be used for {{Q|4167410}}? — [[User:Ivan A. Krestinin|Ivan A. Krestinin]] ([[User talk:Ivan A. Krestinin|talk]]) 19:38, 23 June 2014 (UTC) P. S. Please use [[Property talk:P360|property discussion page]]. This question can be interested not only for English-speaking users.
** What property? You mean what property could be used to mark such a disambiguation page as a "disambiguation page, which is about multiple persons with the same or similar names"? {{P|31}}={{Q|4167410}} would stay as is on those items. --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:59, 23 June 2014 (UTC)
*** {{P|360}}={{Q|215627}} is additional information for {{Q|4167410}}. This claim allows to separate human name disambiguations and another disambiguations. Goals of this project do not allow simple delete information. But we can move information from one property to another. So the question is: what property we will use to mark human disambiguation pages? — [[User:Ivan A. Krestinin|Ivan A. Krestinin]] ([[User talk:Ivan A. Krestinin|talk]]) 21:16, 23 June 2014 (UTC)
**** Wikipedia articles are tagged as disambiguation pages, not as "people dismabiguation page". Even if a page is called "John Smith" and all Wikipedia articles are disambiguation pages linking only to pages about people, that does not mean that it is a "people disambiguation page" or a list of person. It should still be ok to add a link to a movie called John Smith in one of them. It seems to me that {{P|31}}: {{Q|4167410}} should always be enough. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:19, 23 June 2014 (UTC)
**** Same as Zolo. Disambiguation page must have only {{P|31}}={{Q|4167410}}, and IMHO Disambiguation page must be only page that have magic word <code><nowiki>__DISAMBIG__</nowiki></code>. --[[User:ValterVB|ValterVB]] ([[User talk:ValterVB|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:40, 23 June 2014 (UTC)
***** Please see [[:en:John Smith]]. {{Q|10723366}} is used instead of {{Q|6148868}} to indicate "person dismabiguation page". So {{P|31}}: {{Q|4167410}} is enough to indicate <code><nowiki>__DISAMBIG__</nowiki></code>, but does not enough to indicate what template must be used. — [[User:Ivan A. Krestinin|Ivan A. Krestinin]] ([[User talk:Ivan A. Krestinin|talk]]) 04:13, 25 June 2014 (UTC)
******{{reply to|Ivan A. Krestinin}} sorry yes, I had not seen that "human name disambiguation pages" are actually differentiated from other disambiguation pages in Wikipedia. Still it seems rather weird to me. [[:en:John Smith]] contains several links to fictional humans, who are not considered humans in Wikidata, and also a link to a film. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 06:59, 25 June 2014 (UTC)
******{{reply to|Ivan A. Krestinin}} Maybe we should create a new item for those pages in the category "human name disambiguation pages" and make that new item a subclass of "Wikimedia disambiguation page" (and then we can decide later if we include "list of person" there, too). But with disambiguation pages the chance of interwiki-"conflicts" might be even higher here: E.g. Wiki A only lists three human names on some disambiguation page, Wiki B lists those three names plus some movie under the same item/disambiguation page. Disambiguation pages may be difficult to categorize. --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 09:26, 25 June 2014 (UTC)
******* "human name disambiguation pages" idea is interesting. If we continue it we need remove {{P|360}} for list articles too. For example for {{Q|896086}} two claims {{P|31}}={{Q|13406463}}, {{P|360}}={{Q|215627}} can be replaced to single claim {{P|31}}="Wikimedia person list article". — [[User:Ivan A. Krestinin|Ivan A. Krestinin]] ([[User talk:Ivan A. Krestinin|talk]]) 18:26, 25 June 2014 (UTC)
******** With that one I'm fine :) after all the "instance of" says that this is a list article, so "is a list of" property is ok there. --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:39, 25 June 2014 (UTC)

* This is further complicated by the fact that many of these items are appropriate to use as the target for properties '{{P|734}}' and '{{P|735}}'. In some cases articles in one language which are tagged as Disambiguation pages are sitelinked to pages in other languages which are not so tagged e.g. because the articles in the other language have an introductory paragraph about the name before the list of people with that name. These pages are probably better described as {{P|279}}:<Surname> or {{P|279}}:<Given name> rather than 'list of' or 'instance of'.

===We have only one type of disambiguation page===
When a Wikipedia does things differently, it does not follow that we have to follow. We are not lemmings. When a Wikipedia has a disambiguation page with only people, fine. When it has other things by that name fine as well. It makes no material difference to us.

==="is a list of" is used to build a query===
As has been documented in the past, "is a list of" is used to build enough information to build a query in the Reasonator. The use of "is a list of" in combination with "person" is an artefact of how we thought things would be. Now we use "human" in stead of "person". [[User:GerardM|GerardM]] ([[User talk:GerardM|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 06:30, 25 June 2014 (UTC)
:Except that this only works where there is a 'list of Foo' article and a separate article about 'Foo' that the 'is a list of' property can link to. In many cases and many languages the 'list of Foo' article is the only article about 'Foo' so the 'is a list of' property has nothing to point at. Lists of the format 'List of Dukes of Hazzard'; 'List of Mayors of Bumblefuck'; 'List of members of Parliament from Mummerset'; 'Roger (disambiguation)'. It makes a lot more sense to rename the items linked to these articles as 'Duke of Hazzard'; 'Mayor of Bumblefuck'; 'Member of Parliament for Mummerset'; 'Roger' with statements defining these as 'subclass of:Hereditary title; elected official; given name; etc. and then use these as the target for other properties rather than creating duplicate items with no sitelinks for the properties to point at. If reasonator knows some thing is a subclass of:political office', for instance, then it can look for 'office held' statements pointing to this item, or reasonator can just list all the properties linking to the item.

::You conflate two separate things.. When a list is a list in the Wikidata sense, we build queries using the "is a list of". It does not matter what Wikipedia calls something. The approved practice is to name the labels for the property and include what Wikipedia calls list articles.

::: [[User:GerardM|GerardM]]: What is a "list in the Wikidata sense"? Wikidata has items. Because Wikidata includes everything which has a wikipedia page wikidata has some items called 'Lists' but the fact they are called 'lists' don't mean a lot. I understand your proposal that we turn these items into the basis for queries; I just don't agree with you. I think that in most cases these items make more sense if we think of them as a set of similar items which can be the target of statements using {{P|31}} and the subject of a statement using {{P|279}} but 'list of' needs to be taken off the front of the item label first. That is my proposal for what to do with items linking to Wikipedia 'list' articles [[User:Filceolaire|Filceolaire]] ([[User talk:Filceolaire|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:22, 27 June 2014 (UTC)

::::A list in the Wikidata sense is an item with "instance of" "Wikimedia list article". We already use the "is a list of" property to build the basis for queries that function in Reasonator.

:I would propose the third one: Using {{P|217}} qualified by the actual museum using {{P|276}}. Rationale: There might be many catalogues, but the physical item is part of the inventory of at most one institution at a time. A certain collection as a context (e.g. by provenance) cannot be reverted, usually the collection is located within one institution which has a coherent set of accession numbers (cf. the ".GR" in your example). Transfer of the collection to another host institution might end up with a different accession number, thus I'd prefer not too closely associate the institution's accession/inventory number with the collection context. (Proper Catalogue numbers, e.g. from a comprehensive description of the collection which enumerates all items, might be very well associated to the collection and not the institution, but then should be qualified by a Q-item for the catalogue, not the one for the collection). -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:55, 25 June 2014 (UTC)
:Addendum: I'm still uneasy with "Number" (located in) "Institution", but unfortunately {{P|217}} gives no guidance what qualifiers should be used. But inventory numbers ''must'' be qualified by some property with the entity allocating the number as target. Otherwise one has to use the inventory number as a qualifier only - exactly paralleling the {{P|528}} case. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 00:03, 26 June 2014 (UTC)
::It had been suggested in discussions at [[Wikidata:WikiProject Visual arts]] talk pages that we should provide that {{p|217}} should be qualified by {{p|195}} (not {{P|276}}, as this is not directly related to the physical location. For instance, object X may be on a long term loan from institution A to institution B, be physically located in institution B but keep an accession number related to institution A). That said we may still have problematic cases. Objets at the British Museum often have several IDs. Worse, some inventory numbers of the Louvre are used by several unrelated objets.
::I agree with Gymel for catalogues: {{p|528}} should be qualified by {{p|972}}. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:45, 1 July 2014 (UTC)
:::But in Andy's example above the painting belongs to the formerly private [[:en:Garman Ryan Collection]]
::::''The Garman Ryan Collection is a permanent collection of art works housed at The New Art Gallery Walsall and comprises 365 works of art, including prints, sketches, sculptures, drawings and paintings collected by Kathleen Garman [...] and lifelong friend Sally Ryan. [...] The collection was donated to the people of Walsall in 1973 and opened to the public in July 1974.''
:::The inventory number 1973.128.GR however very strongly seems to reflect the acquisition of the ''collection'' by the curent host ''institution''. To me this at least means that it is problematic to qualify {{P|195}} with {{P|217}}. As Zolo pointed out, it is also problematic to qualify {{P|276}} with {{P|217}} and vice versa. What seems to be missing is a property to qualify {{P|217}} with some kind of institutional "ownership" in the sense of "having control" as manifested by the fact that an inventory number was shelled out. The technical term in english might be "holdings" (not sure about museum stock) but neither "in stock" or "held by" would be a good label. What about "administered by": {{C|some item|P217|number|administered by|some institution}} is a narrow statement about the administration of the number, and {{C|some item|administered by|some institution|P217|some number}} would be a statement with respect to administrative control backed by the inventory number - both would be legitimate. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 06:48, 2 July 2014 (UTC)
::::We should probably have defined {{p|195}} more carefully. I thought it meant the institution that was responsible for the artwork (in France, many paintings are considered part of the Louvre's collection even if they are on long term loan to other museums, and are officially owned by the State). 
::::For structural consistency, I think we should completely separate places from institutions. {{p|276}} should use items about phyiscal places (like {{Q|1075988}}) rather than institutions (like {{Q|19675}}).
::::Perhaps we should use the same property for the institution in charge of the inventory number as for the institution in charge of a database ? I have just seen that {{Q|32059}} uses {{p|126}}. Would that be ok ? --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:33, 2 July 2014 (UTC)
:::::[[User:Zolo|Zolo]], that is a good idea. There is also {{P|127}} but I do not know if that is relevant in this case.--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:50, 2 July 2014 (UTC)
::::::Use case for {{P|126}} seems to be the technical ''maintenance'' of bridges and roads, and there also is {{P|137}} (discussed for railway ''operations''). The discussion page for {{P|127}} touches the German distinction between "Eigentümer" and "Besitzer" (papers and facts show it's ''my car'' and nobody may use it without my permission but legal ownership is held by the leasing company). It was unilaterally settled that {{P|127}} should denote "Eigentümer". For museum objects and/or collections this may be relevant in the case of "deposits" (several unmerged wikidata items seem to exist for "depositum"): An entity completely yields control of the item to an institution but keeps his property rights. As I claimed above administering inventory numbers (stockkeeping) is tightly bound to exercising control and {{P|137}} would be the closest to that of the three properties. But I would not exactly call the relation between collection items or collections at a whole and the administering institution / controlling organization as "operating". -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:38, 2 July 2014 (UTC)
:::::::I realized too late that {{p|137}} seemed indeed more appropriate than {{p|126}}.

:::::{{Ping|Zolo}} The Louvre is not very distinctive: (At least in the english version of its home page) the talk about ''the'' collection, then they reveal that the collection is divided into departments, and the individual departments comment on their respective collection(s). Anyway: When an institution acquires individual items one at a time to build its own ''collection'' it may organize that as it suits the institutions needs. However if (part of) an ensemble is aquired which has been build by the collecting activity by some other party (private collectors, institutions) then ''collection'' becomes a more technical term and expresses the provenance. Sometimes there are contractual obligations (a donor demands to keep the donated works together forever) but generally beeing part of a (historical) collection is an important and notable property of items and should not be confused with the fact that it is currently part of ''the collection'' of the owning / holding institution. Over time this new collection context gains importance too, but this is additive, in a sense the items never loose the connection with their former collection contexts, whereas ownership may terminate and be transferred to some other entity. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:06, 2 July 2014 (UTC)
::::::It seems to make sense thanks. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:07, 3 July 2014 (UTC)
:::::As [[User:Zolo|Zolo]] pointed it and for my experience in french museum collections catalogues, the case of an object from a museum collection loaned for a long time to another museum is not rare, and frequent for some collections. In those cases, there are always two (or more) access numbers. So the using a qualifier for {{P|217}} is a good idea but the systematization is not a not necessity ; when there is just one access number, this qualification is implicit with {{P|195}} of the artwork.
:::::> Zolo : For structural consistency, I think we should completely separate places from institutions.
:::::Yes you are totally right, this distinction is very important. Many artworks from museums collections are disseminated in other institutions. The {{p|276}} could not be enough. Places can change and the {{p|195}} is important to indicate an historical and editorial ensemble of objects and could be very usefull for accessing to scientific works about an object.
:::::>Zolo : Perhaps we should use the same property for the institution in charge of the inventory number as for the institution in charge of a database ? 
:::::Maybe but {{P|195}} should be enough. The inventory number is or was given by an institution always in the context of an identified collection.   
:::::In case of many access numbers (and sometimes in the same collection), we could use a "prefered rank" for the access number, if the institution in charge of the conservation has choosen one (an example in french for a collection of Cluny museum sculptures: http://www.sculpturesmedievales-cluny.fr ).  
I agree that the accession number should only be listed as a number released by the database creator, in this case a museum, but it could be a show gallery, a state collection, a long-term travelling exhibition, or whatever. In the Netherlands, the most important painting at the Rijksmuseum (Rembrandt's Nightwatch) hangs on a wall that was built to hold it, but it actually belongs to the Amsterdam museum. Both museums have an accession number for the painting. [[User:Jane023|Jane023]] ([[User talk:Jane023|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:57, 3 July 2014 (UTC)

:I would propose the third one: Using {{P|217}} qualified by the actual museum using {{P|276}}. Rationale: There might be many catalogues, but the physical item is part of the inventory of at most one institution at a time. A certain collection as a context (e.g. by provenance) cannot be reverted, usually the collection is located within one institution which has a coherent set of accession numbers (cf. the ".GR" in your example). Transfer of the collection to another host institution might end up with a different accession number, thus I'd prefer not too closely associate the institution's accession/inventory number with the collection context. (Proper Catalogue numbers, e.g. from a comprehensive description of the collection which enumerates all items, might be very well associated to the collection and not the institution, but then should be qualified by a Q-item for the catalogue, not the one for the collection). -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:55, 25 June 2014 (UTC)
:Addendum: I'm still uneasy with "Number" (located in) "Institution", but unfortunately {{P|217}} gives no guidance what qualifiers should be used. But inventory numbers ''must'' be qualified by some property with the entity allocating the number as target. Otherwise one has to use the inventory number as a qualifier only - exactly paralleling the {{P|528}} case. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 00:03, 26 June 2014 (UTC)
::It had been suggested in discussions at [[Wikidata:WikiProject Visual arts]] talk pages that we should provide that {{p|217}} should be qualified by {{p|195}} (not {{P|276}}, as this is not directly related to the physical location. For instance, object X may be on a long term loan from institution A to institution B, be physically located in institution B but keep an accession number related to institution A). That said we may still have problematic cases. Objets at the British Museum often have several IDs. Worse, some inventory numbers of the Louvre are used by several unrelated objets.

:::But in Andy's example above the painting belongs to the formerly private [[:en:Garman Ryan Collection]]
::::''The Garman Ryan Collection is a permanent collection of art works housed at The New Art Gallery Walsall and comprises 365 works of art, including prints, sketches, sculptures, drawings and paintings collected by Kathleen Garman [...] and lifelong friend Sally Ryan. [...] The collection was donated to the people of Walsall in 1973 and opened to the public in July 1974.''
:::The inventory number 1973.128.GR however very strongly seems to reflect the acquisition of the ''collection'' by the curent host ''institution''. To me this at least means that it is problematic to qualify {{P|195}} with {{P|217}}. As Zolo pointed out, it is also problematic to qualify {{P|276}} with {{P|217}} and vice versa. What seems to be missing is a property to qualify {{P|217}} with some kind of institutional "ownership" in the sense of "having control" as manifested by the fact that an inventory number was shelled out. The technical term in english might be "holdings" (not sure about museum stock) but neither "in stock" or "held by" would be a good label. What about "administered by": {{C|some item|P217|number|administered by|some institution}} is a narrow statement about the administration of the number, and {{C|some item|administered by|some institution|P217|some number}} would be a statement with respect to administrative control backed by the inventory number - both would be legitimate. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 06:48, 2 July 2014 (UTC)
::::We should probably have defined {{p|195}} more carefully. I thought it meant the institution that was responsible for the artwork (in France, many paintings are considered part of the Louvre's collection even if they are on long term loan to other museums, and are officially owned by the State). 
::::For structural consistency, I think we should completely separate places from institutions. {{p|276}} should use items about phyiscal places (like {{Q|1075988}}) rather than institutions (like {{Q|19675}}).
::::Perhaps we should use the same property for the institution in charge of the inventory number as for the institution in charge of a database ? I have just seen that {{Q|32059}} uses {{p|126}}.

::::::Use case for {{P|126}} seems to be the technical ''maintenance'' of bridges and roads, and there also is {{P|137}} (discussed for railway ''operations''). The discussion page for {{P|127}} touches the German distinction between "Eigentümer" and "Besitzer" (papers and facts show it's ''my car'' and nobody may use it without my permission but legal ownership is held by the leasing company). It was unilaterally settled that {{P|127}} should denote "Eigentümer". For museum objects and/or collections this may be relevant in the case of "deposits" (several unmerged wikidata items seem to exist for "depositum"): An entity completely yields control of the item to an institution but keeps his property rights. As I claimed above administering inventory numbers (stockkeeping) is tightly bound to exercising control and {{P|137}} would be the closest to that of the three properties. But I would not exactly call the relation between collection items or collections at a whole and the administering institution / controlling organization as "operating". -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:38, 2 July 2014 (UTC)

:::::{{Ping|Zolo}} The Louvre is not very distinctive: (At least in the english version of its home page) the talk about ''the'' collection, then they reveal that the collection is divided into departments, and the individual departments comment on their respective collection(s). Anyway: When an institution acquires individual items one at a time to build its own ''collection'' it may organize that as it suits the institutions needs. However if (part of) an ensemble is aquired which has been build by the collecting activity by some other party (private collectors, institutions) then ''collection'' becomes a more technical term and expresses the provenance. Sometimes there are contractual obligations (a donor demands to keep the donated works together forever) but generally beeing part of a (historical) collection is an important and notable property of items and should not be confused with the fact that it is currently part of ''the collection'' of the owning / holding institution. Over time this new collection context gains importance too, but this is additive, in a sense the items never loose the connection with their former collection contexts, whereas ownership may terminate and be transferred to some other entity. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:06, 2 July 2014 (UTC)

:::::As [[User:Zolo|Zolo]] pointed it and for my experience in french museum collections catalogues, the case of an object from a museum collection loaned for a long time to another museum is not rare, and frequent for some collections. In those cases, there are always two (or more) access numbers. So the using a qualifier for {{P|217}} is a good idea but the systematization is not a not necessity ; when there is just one access number, this qualification is implicit with {{P|195}} of the artwork.
:::::> Zolo : For structural consistency, I think we should completely separate places from institutions.
:::::Yes you are totally right, this distinction is very important. Many artworks from museums collections are disseminated in other institutions. The {{p|276}} could not be enough. Places can change and the {{p|195}} is important to indicate an historical and editorial ensemble of objects and could be very usefull for accessing to scientific works about an object.
:::::>Zolo : Perhaps we should use the same property for the institution in charge of the inventory number as for the institution in charge of a database ? 
:::::Maybe but {{P|195}} should be enough. The inventory number is or was given by an institution always in the context of an identified collection.   
:::::In case of many access numbers (and sometimes in the same collection), we could use a "prefered rank" for the access number, if the institution in charge of the conservation has choosen one (an example in french for a collection of Cluny museum sculptures: http://www.sculpturesmedievales-cluny.fr ).  
I agree that the accession number should only be listed as a number released by the database creator, in this case a museum, but it could be a show gallery, a state collection, a long-term travelling exhibition, or whatever. In the Netherlands, the most important painting at the Rijksmuseum (Rembrandt's Nightwatch) hangs on a wall that was built to hold it, but it actually belongs to the Amsterdam museum. Both museums have an accession number for the painting. [[User:Jane023|Jane023]] ([[User talk:Jane023|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:57, 3 July 2014 (UTC)

== Change domain of property {{P|576}}? also: What is an "object"? ==

Hi,<br/>
I posted a question/discussion request on the {{P|576}} property talk page (this section here will only be a pointer to that talk page). Mainly this is about the question: Should {{P|576}} apply to the same domain as {{P|571}} as that one is the opposite of the other property? And second question is: What does "object" mean in that description from P571 ("when the organization/object was founded/created")? I mainly wonder about this as I may I want to use {{P|576}} and {{P|571}} for indicating on what date a sports season started and ended. But a sports season is not a physical object, but it could be a concrete one nevertheless (not really sure how to call this in a higher abstraction level, also see https://en.wikipedia.org/wiki/Type-token_distinction on this)?

: To your ontological question: concrete things (tokens) are instances; abstract things (types) are classes.  Enabling type-token distinction is a primary function of {{P|31}} and {{P|279}}.  ''Sport season'' is a class; ''2004 Red Sox season'' is an instance.

: The usage of "object" in the property description in question likely means any ''[[Wikidata:Project_chat/Archive/2013/12#BFO_2.0_.28draft.29|material entity]]'' not covered by an analogous property (e.g. ''date of birth'', for those objects we call ''organism'').

== Gender redundancy ==

Why do we have {{Q|6581097}}/{{Q|6581072}} ''and'' {{Q|44148}}/{{Q|43445}}? Surely the latter pair are redundant, and we can rely in ''instance of'' to tell us whether the subject is human, a horse, or whatever? <span class="vcard"><span class="fn">[[User:Pigsonthewing|Andy Mabbett]]</span> (<span class="nickname">Pigsonthewing</span>); [[User talk:Pigsonthewing|Talk to Andy]]; [[Special:Contributions/Pigsonthewing|Andy's edits]]</span> 22:28, 2 July 2014 (UTC)

: [[User:Pigsonthewing|Andy]], see [[Property_talk:P21#Values_not_making_sense]].  I agree with your position, though.  The current redundancy conflates two properties: biological taxonomic classification and sex/gender.  This is a bad separation of concerns.  I'm aware of the awkwardness in some languages of having a property for ''only'' sex/gender, but given that Wikidata is more of an ontology than a linguistic datastore, I think applying ''male'' and ''female'' to non-human animals makes more sense.

:: [[User talk:Pigsonthewing|Andy]]: At one stage we did use the same item for both these concepts. It was changed because various users said that, in their language, there was no word that covered both male humans and male animals and the same for females. After some discussion the current arrangement was agreed.
:: There was another big discussion about whether we should have separate properties for sex and gender (You didn't ask about this but I thought others new users might be interested in the history). I advocated against separate properties on the grounds that in pretty much every case we have no way of knowing what the biological sex of a person is. We can tell what gender they publicly express and from that we can guess at their biology. After a long discussion we agreed to change the label for P21 from 'sex' to 'sex or gender'. The [[:en:intersex]] article lists five different factors that control or express a persons 'biological sex' and there are a number of other factors related to gender. In the cases where we have specific information on these we can have multiple values for {{P'|21}} with qualifiers to specify which factor each value refers to.

Tying that discussion about sex/gender into this one about male/male animal, we see that there is little appetite in the Wikidata community, at least with this property, for a clear separation of concerns.

== Wikidata just got 10 times easier to use ==

Hey folks :)

We have just deployed the entity suggester. This helps you with suggesting properties. So when you now add a new statement to an item it will suggest what should most likely be added to that item. One example: You are on an item about a person but it doesn't have a date of birth yet. Since a lot of other items about persons have a date of birth it will suggest you also add one to this item. This will make it a lot easier for you to figure out what the hell is missing on an item and which property to use.

Thank you so much to the student team who worked on this as part of their bachelor thesis over the last months as well as everyone who gave feedback and helped them along the way.

I'm really happy to see this huge improvement towards making Wikidata easier to use. I hope so are you.

== occupations and art media ==

Hi I was linking some painting images used as illustrations on Wikipedia to their associated Wikidata biography items and [[Q358629|one of them]] wasn't a painting but an engraving after a painting. So I linked it as an "engraving" with creator=engraver. While doing this, I realized that in English the word for painting (and the enwiki article) is used for the art of painting and the physical object. Same for engraving, so my qualifier "instance of engraving" is actually an "instance of the art of engraving". Don't we need "medium" and then "art of creating medium" for each art form?  [[User:Jane023|Jane023]] ([[User talk:Jane023|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:14, 5 July 2014 (UTC)
: There are distinct items between arts and their respective media, such as {{Q'|11629}} <!-- (no label) --> vs. {{Q'|Q3305213}} <!-- painting -->, and both get listed if you search for "painting"; I believe many others art similarly have distinct items.  Items that are "art subclasses" should not be pointed to by {{P|31}} of any other items, thus [http://tools.wmflabs.org/wikidata-todo/autolist.html?q=CLAIM%5B31%3A11629%5D&nochrome=1 all these items] need to be fixed, for example.  '' [[User:Laddo|LaddΩ]]''  [[User_talk:Laddo|''<small>chat </small>'';)]] 14:29, 5 July 2014 (UTC)
::Thanks, I was afraid of that. I will try to rename the titles of all the items that I see (so tapestry-making vs tapestry, art of engraving vs engraving, art of sculpting vs sculpture, etc). When I am in the middle of an "instance of" I can't see what I am selecting otherwise.

:::We have {{P'|101}} which links to the 'art of' item. This is mostly used with {{P'|106}} so a person can have 'occupation:artist'; 'field of work:engraving' and we don't need to create a separate item for each specialised field. That works for Occupation but from what you say it looks like we will need to create separate items for each type of image so we can classify each image on Commons once Commonsdata is launched. When Commonsdata happens then the qualifiers you are creating can be moved there as properties of the image.

This is actually a bigger job than I expected. It turns out several other languages have combined their articles for "medium" and "art of creating medium", such as "stipple engraving", "steel engraving", and so forth. This means that the Wikidata items need to be separated out. When in doubt I will create new items for the object vs. the creative process (such as [[:en:Painting (object)]].

== What do you wish you had known when you first started using and/or contributing to Wikidata? ==

Hi all,

I recently made some edits to [[Help:FAQ]] as part of a larger sitewide documentation overhaul (more info on this [[Wikidata:Documentation_Overhaul/Summary_and_Feedback|here]]). 

To compare my edits with the previous version of Help:FAQ please see the diffs at http://www.wikidata.org/w/index.php?title=Help%3AFAQ&diff=142538143&oldid=137443709

As you'll see, my changes mostly consist of deleting a few questions that were either duplicates of others or did not seem like they would be questions that were frequently asked, for example, "According to the history of an item I changed, the number of bytes went up or down significantly, even though I only made a minor change. Why did this happen?" I also added in more links to our other documentation.

I'd like to update the page a bit more and re-arrange the questions thematically but first would love your help with improving the content we have.
Could people please have a look at the current FAQ and let me know what is missing? If you're not sure, maybe consider the following as jumping off points:
*What questions did you first have when you started contributing to Wikidata? 
*What did you wish you had known from the start and what concepts or task took some time and perhaps trial n error to learn and understand? 
*If you often help newbies and/or hang out on IRC, what types of questions do you frequently hear from other users?

Please also let me know if you have any concerns about the changes I've made (for example, if I've removed a question that you think is absolutely essential to have on the page). If you see something wrong (like a typo) or something that could be easily improved upon (like an example), please just go ahead and fix it—no need to comment here first!

Thank everyone!. -[[User:Thepwnco|Thepwnco]] ([[User talk:Thepwnco|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 22:52, 4 July 2014 (UTC)

== Deletion warnings, deletion handling via user-subpages, professionalism ==

[[User:Delusion23]] informed me that the following three items appear on a user-subpage of [[User:Pasleim]] and wrote "Please use them in items or provide sources or they are likely to be deleted." [https://www.wikidata.org/w/index.php?title=User_talk%3ATamawashi&diff=143066697&oldid=142784747]:
* canton of Gran Colombia ([[Q17305515]]) - a class for the cantons of Gran Colombia - if no canton has an item, how could I use that on other items? 
* Chuda State ([[Q17318475]]) - a princely state of the British Raj - I have no idea on which item I could use that, it's just one of hundreds of princely states. 
* island group of Kiribati ([[Q17305516]]) - first level administrative territorial entities as defined by FIPS and ISO - if the island groups have no item yet, I don't know where I could use that item. 
Alternatively for all three - How do I add a source?

Instead of tracking via a user-subpage could that please happen in the Wikidata-namespace? Deletions are a serious point of controversy that did let many people leave individual Wikipedias. So there should be a high level of professionalism when handling these. [[Wikidata:Notability]] looks good. Maybe a subpage [[Wikidata:Notability/List of likely unnotable items]] could be created? And then a bot automatically informs users if an item that they had created appears on that list? Or, even easier, a link to the creator is added in the list and then the MediaWiki-software informs the user automatically. [[User:Tamawashi|Tamawashi]] ([[User talk:Tamawashi|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:58, 8 July 2014 (UTC)
:I agree that it would be good if a system like that described by Tamawashi were put in place. Automated messages to talk pages when a page is still showing signs of not being notable after, say, two days would be good. Then if the items are not improved to pass [[WD:N]] after a couple more days the items could be deleted. Unless of course the item is an obvious test page or vandalism in which case it can be deleted straight away. It would also be good if [[User:Pasleim/notability|that particular page hosted by Pasleim]] could be at a more official page. This way more people would be aware of its existance, both item creators and admins.

:The issue with sourcing is an ongoing Wikidata development problem. I'm still amazed the project has had to go on for almost 2 years without any simple method for adding refs and sources being initiated.

== Accessing statements from Wikipedia ==

Hi, I am trying to figure out how to access Wikidata statements from the Wikipedias. I have read [[mw:Extension:Wikibase_Client/Lua]]. It describes how to get a list of properties and the property values. But nothing about qualifiers, sources or rank are mentioned. Does that mean that it is not possible to access qualifiers, sources and rank of statements from Wikipedia pages? If so, is it planned for the future? Thank you for any advice, [[Special:Contributions/94.191.188.21|94.191.188.21]] 11:02, 8 July 2014 (UTC)

::::Not sure about the API, the Wikibase client extension is labeled as "beta version". I think they would make sure not to break existing Lua code at this stage (after all some Wikipedia already use Wikidata), but not really sure about this. Wikibase client documentation is not really good. For fetching qualifiers and other properties, I would take a look at the German Wikidata module at https://de.wikipedia.org/wiki/Modul:Wikidata it has more functionality than the one from the English Wikipedia. For getting the sources, take a look at the "getReferences" function. --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 08:05, 9 July 2014 (UTC)
::::: Thank you, Bthfan. I asked about the stableness of the table format because when doing computer programming it is often considered a bad thing to directly use internal structures in objects. Generally it is better only to use the documented interface methods in order to not restrict the possibilities for further development of the structure. However the problem here is that there are only documented interface methods to get labels, links, properties and property values. So I will have to make my own interface methods (or reuse from e.g. German Wikipedia). I think the Wikidata developers may have a future problem by not delivering their own access methods so direct access to table can be avoided.

== Is Wikidata aiming to become ScienceDirect or PubMed? ==

This is a question of Wikidata notability and how we plan on referencing and sourcing information here. Will there be any future developments that allow for the easy linking to science papers, books, websites etc. Or do we start making items for every single reference in the world [[Q17326780|as I've seen here]] and then link to these items?  We have to reference somehow, but what is the best way to do it? Cheers.

To increase the memory of servers ? The solution you proposed was what I wanted to see in wikidata before we decided to use the current system. I was proposing that solution and after long discussions I was convinced by the current system because it is the most appropriate for multiple use of the same reference.

I agree with [[User:Zolo|Zolo]] and [[User:Snipre|Snipre]] on this.  A source should ideally have its own Wikidata item.  This fulfills a structural need and thus meets our notability threshold per [[WD:N]] criterion 3.  For the impatient, referencing via {{P|854}} is better than nothing.

[[User:Jakec|Jakob]] says "The sourcing system needs to be overhauled so that you can add multiple parameters to a source (url, author, title, etc.)  That seems like a better solution than creating an item every time you want to cite something."  This need is already met by items: those "parameters" already exist properties as like {{P|854}}, {{P|50}}, {{P|357}}, and an ecosystem of other properties described in [[Help:Sources]], as Zolo says.  I agree with Jakob that it's inconvenient to do that, especially for one-time references, but I don't think it's significantly more work than finding and entering data on 'URL', 'title', 'author' etc. and entering them as qualifiers on a source.  However, having that information centralized in an makes it easier to query in interesting ways, and reduces duplicate data entry (e.g. you don't need to list the author each time a paper is referenced).

If [[User:Lydia Pintscher (WMDE)|Lydia]] does allocate developer resources to this, I hope it will be for features like automatic extraction and population of {{P|50}}, {{P|357}}, {{P|577}}, etc. given a URL or URN -- kind of like the game-changing [[:en:User:Diberri/Template_filler|Diberri template filler]].  Emphasizing precision in references, by providing input fields for properties like {{P|P387}} and {{P|304}} in such a tool, would also be great.

:Historical note: [[Q7946|minerals]] are natural substances with a [[Property:P274|chemical formula]] range. Nowadays, the definition of each mineral is done under the patronage of the [[Q268771|International Mineralogical Association]] (IMA). The last accepted modification is summarized in the last [[Q13651014|IMA Master List]], and on scientific papers about each case. The definition changes with improvements in technology and science. Mineral definitions are conventions, and changes in these conventions are small revolutions ([[Wikidata:WikiProject Mineralogy/IMA number references#List of IMA numbers of other special procedures]], for instance). The professors and curators that decide these changes are country representatives at the IMA and are notable. These people published a pile of scientific publications and Wikimedia projects don't have enough scientific editors. Many professors and curators don't have an article on a Wikimedia project, and it doesn't prove that these people aren't notable enough. Their names will still be in a scientific [[Q5292|encyclopedia]] in 300 hundred years time, many professional [[Q2066131|sportspersons]]/ [[Q482999|gladiators]] will lose their notability in 300 years time. In my opinion, CC0-compatibility rule doesn't apply for conventions (agreed upon vocabulary and mineral definitions). No communication is possible without an agreed upon convention. We don't need all scientific references as items but we need the most important ones as items. We need to be able to express changes on Wikidata as '[[Property:P580|start date]]' and '[[Property:P582|end date]]'. --[[User:Chris.urs-o|Chris.urs-o]] ([[User talk:Chris.urs-o|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 05:40, 9 July 2014 (UTC)

:::{{ping|Bthfan}} There are basically two currents of thought: "mergists" and "splittists". The mergists would have to have together the sitelinks to categories and sitelinks to articles in one item, whereas the splittists prefer not to mix them, since they represent different concepts. Additionally, there is the problem that Commons has organized mostly around Categories and not around content pages (understandably so, given the limitations that content pages had to handle dynamic content), but some users don't think that is enough reason to create items for their categories. And yet additionally there is {{bugzilla|47930}}, which prevents us to access sitelinks from unconnected items. For now better to link to Commons galleries in the sitelinks, and link to Commons categories with {{P|373}}.

== Catalog property ==

I have used {{P|528}} (with qualifier {{P|972}}, as stated on the property page) to add external catalog identifiers to Wikidata, where the catalog has no property of its own, e.g. to add {{Q|70425}} to the {{Q|17166797}}. Only later I discovered that "catalog code" apparently means "astronomic catalog code".
* Should there be such a generic catalog property, with a qualifier to specify the catalog, for catalogs that do not have their own property? (I think: yes)
* Should we use {{P|528}} for this? (I think:yes)
As a side note, you can already get all items in a specific catalog annotated in this format, e.g. [http://tools.wmflabs.org/wikidata-todo/autolist2.php?language=en&project=wikipedia&category=&depth=12&wdq=claim%5B528%5D%7Bclaim%5B972%3A17166797%5D%7D&mode=cat_no_wdq&statementlist=&run=Run&label_contains=&label_contains_not=&chunk_size=10000 here] for {{Q|17166797}}. --[[User:Magnus Manske|Magnus Manske]] ([[User talk:Magnus Manske|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:56, 8 July 2014 (UTC)

I think we should always try to make the catalogue name explicit, but there are certainly cases where we can import the identifier now, and add the catalogue name later.

: In many cases languages are defined related to countries and administrative territorial entities for political reasons (Why are {{Q|Q9307}} and {{Q|5146}} considered to be different languages?) so I guess {{P|131}} could be used for languages. 
: 'Ethnic group' very often refers to people with a common language. It may the principal thing distinguishing that group from others so I suppose {{P'|172}} is appropriate for some languages.
: {{P|181}} is meant for animals but I think it could be used for languages as well. [[User:Filceolaire|Filceolaire]] ([[User talk:Filceolaire|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:15, 6 July 2014 (UTC)

::: What you indicate about Galician and Portuguese (as being the same) indicates that it is best that you do not touch languages at all. The notion that you can identify languages as being spoken in a specific "administrative unit" gives often the notion that it is spoken exclusively which is often plain wrong. When you indicate that only a specific ethnic group speaks a language it is typically dead wrong as well. Please do not do this.

As far as I know Galician and Portuguese are distinct, but closely related, and have been considered either separate languages or dialects ([[w: Galician_language#Classification_and_relation_with_Portuguese|classification/relation]]). Are you saying we should not list the regions languages/dialects/language families are mainly spoken in for political regions? Obviously languages are not always spoken by a single ethnic group, but IMO there should be some way to indicate a link between e.g. {{Q|3249806}} and {{Q|2982063}}. I don't know which property to use and whether it would be better to indicate this on the language item, the ethnic group item, or both.

:::::::::I don't see the problem. If there are significant communities of speakers in New York (or wherever), it can be indicated with the property. Perhaps which areas are the place(s) of origin of the language could be indicated using a qualifier. Already sources like MultiTree contain this kind of information, for example indicating that [http://multitree.org/codes/cab Garifuna] is spoken in the United States. Ethnologue has information for each country a language is spoken in, [http://www.ethnologue.com/language/spa example] ("Also Spoken In"). Why would this be problematic? I think collecting this information would be useful. It could also help to make maps like [http://wals.info/languoid/genus/pamanyungan this], if we allow coordinates for languages spoken only in one region (for example, many dialects are only used in one village/town).

== Query all items that have coordinates but no image ==

Can somebody help me with a query for all items that have {{p|625}}, but no {{p|18}}? I would like to create a map showing where images are missing. Possibly compile a few maps for the next ''Wiki loves [...]'' contest. A {{Q|935809}}-file would be ideal for importing into QGIS.<br>
On a related note we should lobby the Commons-app-people to get Wikidata-data into the Commons-app (https://www.mediawiki.org/wiki/Wikimedia_Apps/Commons). A mobile-app that leads people to the places where images are missing would be really cool. Gamification of the image-hunt (similar to the tools by {{ping|Magnus Manske}}) would probably be a big boost to Commons. Too bad we don't have a global requested image database.

[[User:Micru|Micru]] has now created {{P|1365}} and {{P|1366}} to work alongside {{P|155}} and {{P|156}}. The plan is that P155 and P156 are for books and albums and items in a series where new items don't replace previous items while P1365 and P 1366 are for political offices and states where the previous item is replaced. 

I have done some work on the labels and descriptions in English to try and make this clear (including changing the labels from those in the subjectline above) but they could probably do with some more eyes to check what I have done and to modify the labels in other languages to reflect this change.

As long as broad-meaning properties don't cause distress we should prefer them, otherwise we should seek precision.

First of all, it would be great if someone can define for me the terms 'replace' and 'follow'. I can't comment on the use of these properties without knowing what kind of relational concepts we are talking about here. To me, the word 'follow' implies that the preceding entity no longer exists in the status it had, as the succeeding entity obtained the aforesaid status; this status can only be occupied by one entity at one time. The word 'replace' implies that the preceding entity ceases to exist entirely and is replaced by the succeeding entity, as the succeeding entity is considered to have some characteristics pertaining to the preceding entity (e.g. building A was demolished and was ''replaced'' by building B because building B is built at the location where building A was). Please tell me if I am getting the correct idea about the two terms. Using the term 'replace' in the descriptions of {{P|1365}} and {{P|1366}} does not exactly help. —[[User:Wylve|Wylve]] ([[User talk:Wylve|<span class="signature-talk">talk</span>]]) 16:01, 23 June 2014 (UTC)
:I'm not a native speaker, but "follow" seems to imply some common direction. Thus "prince X" can ''follow'' his father "king Y" on the throne, however "duke Z", after having slaughtered king Y and all his kin cannot follow on the throne but only replace him (but may - after having been bitten by a rabid dog - soon ''follow'' king Y to the grave: common direction again...). The intended distinction of the properties is as follows: If some office or position can be taken only by one item at one time, the next holder of that position ''replaces'' the previous (demolition of the preceeding item is not necessarily implied, see {{P|167}} for that). George H. W. Bush is still alive, but he was president of the U.S.A. and as such was ''replaced'' (succeeded) by Barak Obama. ''Following'' on the other hand is intended for positions you cannot loose, like being the 41th novel in a series: This will be eternally followed by the item constituting the 42th novel, at least from the time on when the 42th item in that series is published. However George H. W. Bush was the 41th president of the U.S.A. and in a sense still is, because noone ever can take that exact position. And in that sense Barak Obama ''followed'' him in office, occupying presidency number 42. The different properties IMHO ''try'' to reflect different attitudes of simultanity or exclusivity we have towards novels-in-series and presidents-in-offices (number 41 Bush was ''the president'' and now is ''a former president'', whereas number 41 Book always was ''a novel'' and still is: it never turns into a "former novel"). Regarding a series "book of the month" might carry both aspects, thus perhaps the difference is not at all in the relation itself but only a nuance in emphasis. Much seems to depend on the actual wording of the list involved: Given a "series" (of whatever, e.g. all U.S. presidencies from past to present) we take a more distant point of view allowing to regard several items at once thus they "follow" each other in the order of the given series. Specializing our view to the generic item in that series (e.g. ''The President'') it turns into something more exclusive: The item of our focus has to be "removed" from the slot before the next item can take its place and become the object of our observation. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:27, 23 June 2014 (UTC)
::[[User:Gymel|Gymel]]: My understanding is that when Prince X becomes King X then King Y has to stop being King first so King X replaces King Y - there is only one king at a time.
::On that basis 'Replaced by' is the appropriate property for hereditary offices, political offices, states, buildings. One has to end before the next can begin. By this logic 'sports league seasons' should use this property since each season is separate. Even if there were some odd case where the end of one season overlapped the start of the next they would still be separate items, one replacing the other.
::'Follows' is the property for TV shows, books, albums, integers and other members of series where there is an order but later items do not replace earlier items. Where the publication order is different from the internal chronology e.g. the Star Wars movies, then the item can be described as 'part of:Star wars chronology' and as 'part of:star wars publication order' and each of these statements can have 'follows' and 'followed by' as qualifiers.

::: {{Ping|Filceolaire}} This seems to add more problems than it solves. Plus it seems to be tight by cultural meaning of words. Do you have an example of actual statements where the type of the items in the sequence is not enough to affect the meaning of a statement ? For example :

::::: [[User:TomT0m]]. No I don't have a case where the meaning cannot be guessed from the domain. Nevertheless I disagree that the properties are tightly linked to the meaning of the words. 'Follows (but does not replace)' and 'Replaces' are slightly different concepts. The confusion arises because these concepts can both be represented, in English and related languages, by the phrase 'preceded by'. Having two separate properties seems to me to unlink the concepts from the language. Your mileage may vary.

:::::: {{Ping|Filceolaire}} It's way easier to add aliases to only one property if it is not ambiguous and adopt a more generic definition. It makes the whole thing simpler and reduce the risk of bad uses. I think we can type the whole sequences : a building can replace another building in the sequence of building that came in the exact place, there cannot be both. An album can follow another album of some author on its all time work sequence, or in the subsequence of work he played with a guitar or whatever. I think we're fine an parcimonious with a ''sequence'' concept, and two properties defining the places of items on this sequence expressing precedence and ''followance'', or the rank, in this sequence. Then the type of the sequence gives the other properties : there is only one King of Britain at a given moment in time, there is only one building, a work do not usually replace another, except in the sequence of films that are played in a given room in a cinema. <span class="mw-code" style="text-align:right; display: inline-block; padding: 0.1em;">[[User:TomT0m|TomT0m]] <sup>([[User talk:TomT0m|talk]])</sup> </span> 18:45, 24 June 2014 (UTC)
::::::: If you want to play with definition, in the case of a king position, if the previous is dead, you can't use "replaced by". You can use  "replaced by" if you have something and you change it. But if the previous king is dead, you can't take him out of its place to put another person. The place is available. In that case the correct term is succession. Then if we want to go further, if a king gives up and choose its successor, you can't use *replace by* because a replacement implies an external cause (no body can say I replace myself). So if you start to distinguish between the different cases, you open the door to a lot of detailed new properties like one property for the change of a person at a position when the previous left or died (typically a king), another one for the change of a person at a position when the previous one is still alive like in election.
::::::: By the way a good example. Can we say that the movie {{Q|42051}} is followed by {{Q|17738}} ? If we take the story or the title of the movies, yes, but if we take the "movie release", no. That's a very good example. Do we need a new property to be able to do the link between {{Q|42051}} and {{Q|17738}} ? 
::::::: We need a property defined not by a word but by a concept: "in a list of sequential elements this element is followed by this one". In that concept we do not define the link between the elements, the nature of the elements defined the relation between them: in the case of a king, this is a succession, in the case of political or professional position this is a replacement, in the case of books this is a story evolution, in the case of musician's albums this is the released date,... Again a property should be a concept and not a word. If a language can't translate the concept by an unique word, we can use a sentence or to put something like "replaced by (building)/succeed by (person)/..." for the label. The problem of the Chinese translation is not a real problem because it is a language problem and languages defines words acording to a context. The question is it is a real difference in the concept ? Then do we need to distinguish in term of data structure meaning do we need to do the difference with help of several properties to perform queries ? I speak here about logical concepts and not about words because if the concept is the same but according to context you can use different words, the concept can be described by a list of words and you don't need several properties. 
::::::: So in the case of interest, we have to stop to use words but to use concepts. If I understand well we need two properties for the next concepts:
::::::: *B takes the place of A in the sequence, but A still exists
::::::: *B takes the place of A in the sequence and A doesn't exist anymore.

:::::::: The major confusion here is that we are seeing "A" and "B" as "entities" as opposed to "entities in a certain state". "Entities in a certain state" does not only concern the entity itself, but its condition. In the king example, "King B" does not replace "King A", as that's a logically incomplete statement. What we should be saying is that "Person B as the King" replaces "Person A as the King", hence rendering the former statement false and the latter true. In the example of creative works, {{Q|47209}} does not replace {{Q|43361}}; "{{Q|47209}} as the newest novel in the Harry Potter book series" replaces "{{Q|43361}} as the newest novel in the Harry Potter book series". The notion of "existence" should be about the existence of the condition that the entity in question is in, not the existence of the entity itself.

I think the propert(y|ies) we should have should allow to answer the questions: followed by what sequence, sorted according to which criterion ? There can be many submeanings to "followed by" (superseded by, replaced at the same location by, functionnally replaced by, merged into...), and I do not think it can all be solved by using more specific properties. It seems to me that we should rather try to have a consistent use of qualifiers here (I'd probably say: always use a qualifier for defining the sequence, and add one for the ordering criterion when it is not chronological). --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:34, 25 June 2014 (UTC)

=== On the usage of {{part of}} ===

I'm still not convinced. It took a long discussion to sort out correct uses of part of, with {{U'|Micru}} and {{U'|Markus Krostch}} amongst others. In the context of any kind of sequences, I think a new property like ''in sequence'' would be better and less confusing than using a property used for whole/part relationship : the nature of the items is not the nature of the list. {{Part of}} fits for physical objects composing a bigger physical object, I don't think it fits of a king sequence is composed of kings.

:[[User:TomT0m|TomT0m]]: I agree with you, actually I wanted to write "part of set", but by mistake I put a colon where there should be none (corrected now). Regardless of how we call the property ("part of set" or "in sequence"), I would do it the other way around  {{C|King II|in sequence|Kings of Country X|preceded by|King I}}. The reason is that it is more clear to have that grouping in the cases where an item belongs to more than one set.--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:45, 25 June 2014 (UTC)

:: [[User:Micru]] I can see the case for a new <in sequence> or <part of ordered set> property for TV shows, books, integers, elements, football league seasons, etc. I would even use it for days of the year (common year or leap year) and state that January 1 follows December 31.

:::*start two property proposals for: "in sequence", "sequence order"
:::*start a property deletion request for: {{p|1365}}, {{p|1366}}), {{p|167}}
:::*change the labels of [[p:p155]], [[p:p156]] to something more neutral, like "previous", "next"

Having to double-specify the presidency by using {{C|''X''|in sequence|Q35073}} and not getting rid of {{C|''X''|P39|Q11696}} at the same time seems rather awkward. Also we have to give some "flesh" to {{Q|35073}} and therefore we must associate the individual presidents to the list anyway. What if we do not state {{C|Q207|in sequence|Q35073}} in the {{Q|207}} item but rather in the list item {{Q|35073}}? This would imply creation of the inverse property to "in sequence", namely "has member in a (partially) ordered set" and we would be able to formulate {{C|Q35073|has member ...|Q207|P156|Q76}}. -- [[User:Gymel|Gymel]] ([[User talk:Gymel|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 15:53, 26 June 2014 (UTC)

===Proposed conventions===
For sorted sets:
*in sequence: A and B belong to a sorted set. B(in a certain state) takes the place of A(in the same state) in the sequence, but A no longer exists in the same state (but it may exist in another state). Main use: sorted lists of only one element valid at any time (e.g. buildings in one location). Use narrower properties where appropriate (e.g. {{p|39}}).
*in series ([[P:P179|p179]]): A and B belong to a sorted set. B(in a certain state) takes the place of A(in the same state) in the sequence, but A still exists (in the same state). Main use: sorted lists with all elements valid at any time (e.g. creative works and abstract concepts)
For unsorted sets (related to [[Wikidata:Requests for comment/Refining "part of"|this RFC]]), no change to the labels is proposed, but I changed them just now for the sake of making easier to understand what they mean:
*in set ([[P:P361|p361]]): A and B belong to an unsorted set of their same domain (physical, event, abstract), but they are not similar to the set
*in similar set ([[P:P279|p279]]): A and B belong to an unsorted set of their same domain (physical, event, abstract), and they are similar to the set
*in strongly similar set ([[P:P31|p31]]): by their strong similarity (mostly grounded in their real life existence), A and B form an unsorted set defined by all their shared characteristics.

Shall we go ahead with this? It would need a new property "in sequence" plus two additional ones:
* sorted according to property: which property is to be considered when sorting (start date, birth name, etc)
* sorting criteria: according to which criteria the set is sorted (ascendent, descendent)

:::[[User:GerardM|GerardM]], thanks for your feedback.

===Extension of the property "series"===
Just wondering, will the property proposal for "in series" happen soon? Or is this currently part of the RFC discussion at [[Wikidata:Requests_for_comment/Refining_"part_of"]]? At least for sports seasons/events (there are a lot of items like that) "in series" would be useful to connect those to an "upper" topic. This would a good alternative to using "instance of" with an generic season/event item for this series and/or using "part of" on every season/event item. We could also think about changing the meaning/definition of {{P|179}} though, currently that one is for creative works only. --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 08:22, 7 July 2014 (UTC)

== API: simplest way to obtain most used values for property ==

Hi. I'm in progress of creating new gadget for person infobox edit, and there is a non-urgent question. I have a field related to {{P|P106}}. By default such field allow to enter reference to any wikidata item. But it will be much better to provide user the list of most used values here, so he can quickly select of them (or enter his own, if he don't like the TOP 10 one). So the question is: how to obtain the most used values for any specific property? It is not need to be direct API access -- i can ask bot to query some other page (from toolserver) and update gadget JavaScript "dictionary" once per day. -- [[User:Vlsergey|Vlsergey]] ([[User talk:Vlsergey|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 08:26, 11 July 2014 (UTC)

== Instance of by (music) albums ==

I couldn't find any discussions on what claim items about albums should use, but I found two ways how it has been done so far.

* In some items there is used simple claim {{P|31}} : {{Q|482994}} and nothing more is specified.
* In other items there are used claims like {{P|31}} : {{Q|208569}}, {{P|31}} : {{Q|209939}} etc. (subclasses of {{Q|482994}}).

What is better? To use the simple claim or to use more specific claims with {{P|31}}?

{{Ping|Succu|Tamawashi}} Hi guys, I don't want to enter this troll, but I'll just say I'm preparing a variation of {{tl|superclass tree}} who will show something like that, I'll take a taxon example, based on the {{instance of}} informations. It will generate, using just {{instance of}} and {{subclass of}} claims, tables like this for an item : 

{|class="wikitable"
! class !! type of class
|-
| ...
| ...
|-
|'''animal'''
|''reign''
|- 
| ...
| ...
|- 
| '''xerus'''
| ''genera''
|- 
| '''xerus xinauris'''
| ''species''
|}

The advantage of this is that this will demonstrate how powerful we can be with keeping genericity : this will not only work for taxas themselves, but also for any class of items for which the superclasses have {{instance of}} statements. The table will be ordered by class inclusion, naturally.

== new GuidedTours at Wikidata:Tours ==

Hi all,

I am pleased to announce the release of two new GuidedTours—we now have interactive tutorials for editing items and for editing statements! Both tours are available from the [[Wikidata:Tours]] portal. Go ahead and try them out, and please share with others who may be interested. Feedback can be left on the portal talk page at [[Wikidata_talk:Tours]] —I'm also planning on conducting some user testing with people who are not already familiar with Wikidata.

== Pages do not load properly when using Firefox ==

I am mainly using Firefox 30, and I find out that data item pages do not load properly when using Firefox, including:
* Not showing "(xx entries)" which should be next to "Wikipedia pages linked to this item"
* When clicking [edit], instead of showing a field for inputing new link and the options [remove] [cancel] on the smae page, it links to another page in [[Special:SetSiteLink]]

:::[[User:Tamawashi|Tamawashi]], that depends.

== problem linking articles (Yeşilova, Aksaray) ==

Dear friends,

I'm trying to link the en.wikipedia article 'Yeşilova, Aksaray' to the de.wikipedia article 'Acemhöyük' (this is the same place). But I'm running into some technical glitch that already happened before (I brought it up here before). I keep getting error messages. I'm using Ubuntu/Linux.

When I try to link Yeşilova, Aksaray to Acemhöyük, this is the error message that I get:

″The link [//de.wikipedia.org/wiki/Acemh%C3%B6y%C3%BCk dewiki:Acemhöyük] is already used by item [[Q8438175|Q8438175]]. You may remove it from [[Q8438175|Q8438175]] if it does not belong there or merge the items if they are about the exact same topic.″

When, from the German side, I try to link Acemhöyük to Yeşilova, Aksaray, this is the error message that I get:

"The link [//en.wikipedia.org/wiki/Ye%C5%9Filova,_Aksaray enwiki:Yeşilova, Aksaray] is already used by item [[Q8003207|Q8003207]]. You may remove it from [[Q8003207|Q8003207]] if it does not belong there or merge the items if they are about the exact same topic."

People using some other computer systems apparently don't run into this problem.

== Calendar model: only display attribute or storage model? ==

Hi. According to [https://www.mediawiki.org/wiki/Wikibase/Notes/JSON#time this page], calendarmodel of time type is part of storage data, i.e. defines the value of stored time (i.e. we need to know both calendarmodel and time to convert to Gregorian calendar). But according to [https://www.mediawiki.org/wiki/Wikibase/DataModel#Dates_and_times this page], calendarmodel "should be used to ''display'' this time value". So, which page is correct?

== Wrong merges ==

I had worried that this will happen, and it did happen - I just discovered 10 items on administrative units in Thailand, which were wrongly merged into same-named items on different units. The damage done by the merge itself is relatively easy undone, asking for undeletion and doing two reversion. But much more work were the linked items - instead of questioning a merge of two items which had links from other items (not to talk of a different description, statements with different values), all of the links were simply changed to point to the new target. I hope I could find and revert all. Really hope the real redirect will come soon, that will make it much easier to revert wrong merges... Please, when reviewing merges be more careful, I know it is a stupid routine job and in 95% of the cases the merge is justified, but with the 5% quite some damage could done. The worst of the 10 - the Wikivoyage articles on a village on the island Ko Samui ({{Q|14203501}}) was merged with a district of Bangkok ({{Q|302711}}).

::{{ping|Ahoerstemeier}} At least one Wikipedia with at least a stub for each could prevent such things. I looked at the items, for the class item "district of Bangkok" there is only one article in the Russian Wikipedia. So, not even the classes are covered well. Another way to reduce chance for wrong merges between different types of administrative entities would be to include the class name in the label, the village would be "Bang Rak" and the khet would be "Bang Rak District". So, any of the "Washington County" would less likely be merged with "Washington". [[User:Tamawashi|Tamawashi]] ([[User talk:Tamawashi|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:36, 15 July 2014 (UTC)
:::As far as I know, things like "County" don't belong into the item label. The description was filled correctly, and if the one who did the merge would have read it, he/she should have noticed that the two are different things. And even if adding the type to the name - for example there are about 30 subdistricts named Nong Bua in Thailand, so you want to have a full disambiguated name as item label? Having robot created articles in one Wikipedia isn't a good idea either, we have enough problems with robot articles already, see the tenthousands of dupes with the robot created taxons. And which Vietnamese will ever edit an article on a village in Turkey - but they have all those as robot created articles (and many of them have items which must be merged with the item linking the article on the Turkish WP). Having a junk Wikipedia to have articles only there to prevent wrong merges it a very queer solution to this problem. And not sure if the Thai Wikipedia would be happy to have all those articles automatically created, so far there are no robot articles there. The merge game is a risky thing, it makes things easy which take quite some work to clean up, on the other hand there are still lots of duplicate items still to be found and done.

== Desert Island Discs; other BBC programmes ==

Hundreds of notable people have appeared (a few, twice) on the BBC Radio programme  [[:w:Desert Island Discs|Desert Island Discs]]. These are listed in subpages of [[:w:List of Desert Island Discs episodes|List of Desert Island Discs episodes]].

How should this be shown? Should we have a specific Desert Island Discs parameter, or a generic "was subject of BBC programme", which take a PID or URL as a value?

== New complete easy PHP lib for accessing and manipulating Wikibase sites ==

Hello all!

This is just a quick note to say that I have finished implementing my wikibase api library which can be found [https://github.com/addwiki/wikibase-api here] called wikibase-api. The new release is 0.2 which covers all aspects of the wikibase api, getting entities, merging items, creating claims etc.

The library uses a few other custom libraries for interacting with the mediawiki api but then uses many of the same libraries as using in Wikibase itself, such as the data model, datavalue and serialization components. I have already seen some use of the library and if anyone has any comments / needs help just ask!

== Duplicate information with occupation and subclasses ==

Hello there,

I've noticed that over the last few days/weeks some of the items on my watchlist have gotten new claims with property [[Property:P106|occupation]] and value [[Q639669|musician]] although they already have a claim that they're a [[Q36834|composer]] which is a [[Property:P279|subclass of]] musician. Examples of this include [[Q155124|Michael Giacchino]] and [[Q235077|Jerry Goldsmith]].
I do think this is just duplicate information and the musician claim should be removed. I did try to find earlier discussions about this but failed and I'm a bit reluctant to remove this information without knowing it's the right thing to do.
So should I go ahead and remove the musician claim again or is this valid information? --[[User:Mineo|Mineo]] ([[User talk:Mineo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:08, 6 July 2014 (UTC)
: {{Ping|Mineo}} This is not a problem. A class regroup individuals who have same characteristics. Musicians are people who plays music. Perhaps even musicians might not have music as a main occupation. In languages such as OWL2, classes can be defined with a so called ''Class expression'', for example the class ''Musician'' can be defined as ''Human or animal who has music as an occupation or hobby''. In those languages, and OWL is an inspiration and a precedent for us all to build Wikidata. Classes are also useful for defining guidelines for properties. For example if we have a property ''plays instrument'', we can define the constraint that usually item who will have this property are instances of the class <musician>.
: Of course then there might be an abuse and we could define a lot of classes. As {{U'|Emw}} likes to state,  in OWL classes might not be explicitely stated, and can be inferred by a program who understans class expressions. Wikibase itself can not atm and it's not in the roadmap atm. 
: In the case of ''Musician'' though, I don't think it's a problem to use this class as it's obviously a class we use all the times. When we say ''Musicians make life happier'' for example. We refer implicitely to ''people who plays music''. 
: We should add words about this in [[Help:Classification]]. <span class="mw-code" style="text-align:right; display: inline-block; padding: 0.1em;">[[User:TomT0m|TomT0m]] <sup>([[User talk:TomT0m|talk]])</sup> </span> 19:38, 6 July 2014 (UTC)

* [[User:Mineo|Mineo]], good point, I agree that claims like "Michael Giacchino ''occupation'' musician" can be removed given that the claims "Michael Giacchino ''occupation'' composer" and "composer ''subclass of'' musician" exist.

::Arguably, a musician is not restricted in the same manner as a more defined "occupation". Was Frederick the great a musician or both a flautist and a composer?? Or is it best to indicate that he was a musician and dabbled in composition and playing the flute?? Given that we use occupation it is clearly wrong in either case. 

::An other argument to use musician is that many of our sources do not differentiate between the many roles. As at this stage the lack of information is out biggest problem, it is to be preferred to harvest such information now and once we have decided what is the best approach we can easily modify in any which way.

== How to handle currency amounts, and other unit amounts ==

A normal way to store monetary amounts in a database would be to use two properties, a '''currency amount''' property and a '''currency''' property (qualifier). This is how I always used to go about this when designing and coding database software for financial companies.

Reasons for this:
* the '''currency amount''' data would be numeric data only (no $ symbols, etc), this allows for mathematical operations to be carried out on the data
* if a new currency is introduced, there is no need for any new coding. Just a case of setting up a new item for that currency, and use it straight away.

This method could probably be used for other types of unit, such as kilometers, kilograms, and so on, for the same reasons as above.

Should we adopt this approach? If so, we can go ahead and propose new properties on this basis. [[User:Danrok|Danrok]] ([[User talk:Danrok|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:51, 15 July 2014 (UTC)
: You already know https://www.wikidata.org/wiki/Wikidata:Property_proposal/Pending/2 or better said https://www.wikidata.org/wiki/Wikidata:Property_proposal/Pending/2#Currency ?

== GSoC '14- Wikidata Web Annotator : Final Testing Phase, Bug and Improvements ==

This is an update report for Wikidata Web Annotator under GSoC'14
I have almost made everything ready for testing.
I have setup the test site [http://tools.wmflabs.org/wikidata-annotation-tool/WikidataAnnotationFeeder/tests/simple_tests/pundit.html here]. 
First login using OpenID to authenticate with the Pundit software.
Try selecting some text, then use annotate text option, futher use Pundit's triple composer to compose triples using selectors and vocabularies retrieved from Wikidata.
Subject and Object are to filled with Wikidata Items, while Predicates with properties.
Check for notebooks(in Pundit notebooks are the containers for annotations) in right most corner of the plugin by clicking on your name > selecting manage notebooks. Notebooks must be public for push to work. Now after annotating use Push to Wikidata button as shown in the figure below
[[File:Web-Annotator-Push-Button.png|center|thumb|Push to Wikidata Button]]

This will open a new window where you can select which annotations are to be pushed. You must authenticate with Wikimedia before doing that as Wikidata is fed by using your Wikimedia username. After this select the annotations you want to push and the click on the 'Push annotations' button, status column will show you about the progress of the push.

I have tested it but not completely.
I have checked for most of the cases like:
1. If claim exists-> then try to push references only.
2. If not create claim -> then push references.
These are just example of cases I have checked upon, there is much more. You all are welcome to test the Annotator so we can further move on to package it as plugin. Discuss the issues, bugs etc.
Also test page may take time to load.

[[File:Web-Annotator-Workflow.png|thumb|right|Workflow]]
Example page which has been fed with this annotator is https://www.wikidata.org/wiki/Q2336535.
In this item, claim for P277 has been wholly added with references via Annotator.
While claim for P106 was already existing and I have added references to it via Annotator.

Here is flowchart showing the workflow:

== Multiple claims when a person has received an award multiple times? ==

When a person has received an award multiple times (for example in different years), should one then tag this with multiple claims like this:<br/>
{{P|166}}="some award", qualifier: point in time=2002<br/>
{{P|166}}="some award", qualifier: point in time=2010

or use multiple qualifiers for one single claim?<br/>
{{P|166}}="some award", qualifiers:point in time=2002, point in time=2010

::I tend to use the first format when dealing with things like {{P|39}} or {{P|54}}, because those tend to be more complicated with both start dates/end dates and other qualifiers.

: I would enable the "Merge" gadget at https://www.wikidata.org/wiki/Special:Preferences#mw-prefsection-gadgets in your settings. Then you get a "Merge with..." link/button at the top of the Wikidata website under the "More..." menu. With that one you can easily merge two items. The problem in your case though is that those items have interwiki links that conflict with each other. Both have a link to the English Wikipedia, a Wikidata item can only store one link per Wikipedia (language). So this one also needs to be resolved at the English Wikipedia, those two articles probably should be merged into one single article. BTW: Did you manually insert the time stamp in your signature? Somehow looks wrong ;) --[[User:Bthfan|Bthfan]] ([[User talk:Bthfan|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:46, 9 July 2014 (UTC)

So far I received no backlash, but the guy was very dead and the info looked 100% covered. This one is going to take some time, because it's a recent death and they are both new articles. The same rules hold as for here: oldest article trumps newer one, so I would say "Castro de Destroyer" is where the item should point to, but it's best to just wait it out a week or two - I see a merge template is already in place.

IMO it should just do things that would be easy review and revert-able by other users and a cross-wiki request Template:Merge adding is outside of its goal however I will not stop anyone else to implement such ability on merge.js itself. Just IMHO requesting content merge is a prestep of an actual item merge, you see a lot of specially lengthy articles on enwiki that is not merged after years of requesting merge and this essentially could be related on activity of that wiki community so it is not an action that after a request and just a short time would be possible.

== Wiki Loves Monuments UK ==

This year's [http://www.wikilovesmonuments.org.uk/ Wiki Loves Monuments UK] would like to try something new: Instead of managing objects in large tables on Wikipedia (''shudder''), they should be proper Wikidata items! We are talking about English, Welsh, Scottish and Northern Ireland grade I and II* buildings; a first estimate is 50,000 objects. Quite a few of them are already on Wikidata, and all of them should be automatically notable due to their grade status. I will soon get the "official" lists of objects, write a tool to find the ones we already have, and to create the ones we are missing. At the very least, objects created through this tool will have name, coordinates, grade status, and possibly short descriptions and "administrative unit". Through the previous and upcoming WLM, most of them should also get an image or two. I just wanted to get everyone here up-to-date, and prepare you for a potentially large influx of building items without Wikipedia articles. I think this will be a major win for both Wikidata and WLM! --[[User:Magnus Manske|Magnus Manske]] ([[User talk:Magnus Manske|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:42, 16 July 2014 (UTC)

== Main page redesign ==

Hey folks,

As part of my internship and continuing efforts to improve outreach for Wikidata, I'm now working on updating the Main page. I've put together a summary of areas for improvement and recommendations for a redesign at [[Wikidata:Portal_Redesign]]; please review and comment when you can. You can leave feedback or other suggestions at [[Wikidata:Portal_Redesign#Feedback]]—ideas and brainstorming on possible visuals to include and ways of featuring fresh and dynamic content (without the need for constant maintenance by users) are very welcome! 

FYI, I am also now working on a redesign mock-up of the Main page and will be sharing this in the upcoming days so there will be another opportunity to give feedback before any changes are implemented. Looking forward to your comments! -[[User:Thepwnco|Thepwnco]] ([[User talk:Thepwnco|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:52, 17 July 2014 (UTC)
== How to handle native language names? ==

What's the best way to handle native language names and labels? For example, we usually wouldn't use a Chinese, Cyrillic, or Greek script for an English label, so we'll transliterate it into Latin/English and use that (e.g., 李卓鑫 → {{q|6539344}}<!--Li Zhuoxin-->, Велимир Милошевић → {{q|12749668}}<!--Velimir Milošević-->, Αλέκος Λουμπαρδέας → {{Q|16909134}}<!--Alekos Loumpardeas-->). However, what should we do with the name in the original script? That's probably information we want to keep in Wikidata. I've been adding it in as an alias, because my transliteration might be wrong or someone might search for it that way, but do we have a better way to handle this or a property for it? This might be waiting for the multilingual datatype, but I figured I'd ask. '''[[User:Cbrown1023|<span style="color:green">Cbrown1023</span>]]''' '''<small>[[User talk:Cbrown1023|<span style="color:#002bb8">talk</span>]]</small>''' 03:15, 15 July 2014 (UTC)
:For one thing, the name in Russian should be used for the label in Russian. I would also support adding more string-type "name" properties, but that is a tricky and disputed issue. We currently only have {{p|513}}. There is also {{p|734}} and {{p|735}}, but they are of item-typed.--[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:19, 15 July 2014 (UTC)ced: [[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:49, 15 July 2014 (UTC)

:::Sorry, typo, this is the onle I meant to cite. The description states "only if different from current name" which seems a bit strange. This property is monolingual while there is one label per language, so there has to be languages where the label is different from the birth name (we currently only have item-type properties for that and that seems a bit fragile). Beside I would split between name and surname. On the whole the name-properties ecosystem seems to remain incomplete. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:49, 15 July 2014 (UTC)
: For Chinese names, I would use the [[w:Pinyin|Pinyin]] romanisation for people who are generally associated with or live primarily in the People's Republic of China (e.g. {{q|15029}}). For people who are associated with or live primarily in the Republic of China (Taiwan), then I would use the [[w:Wade-Giles|Wade-Giles]] romanisation system, which is more popular there (e.g. {{q|233984}}). For people who lived in ancient China (i.e. pre-Republic era), I would use pinyin for their label and put Wade-Giles as their alias.

:I am not clear about how this transliteration property would be used. It seems to work best as a qualifier of some string-type name property. But currently, the name is mostly expressed through two item-type properties {{p|734}} and {{p|735}}.

::{{ping|Zolo}} The transliteration property would work as a qualifier of any property with string or monolingual datatype. Nominative properties that use the item property, can also make use of this property by using a [[Wikidata:Property_proposal/Generic#label|generic label property]] and qualifying it with "transliteration type".
:: Ideally the label system of item pages should be refurbished to link somehow the properties that contain labels and the item labels themselves.

:::{{reply to|Micru}}. Digging a bit the Tsai Ing-wen example. How do we say that here wade-giles name is Tsai Ing-wen and here pinyin name Cai Yingwen ? For the surname we could have
:::*{{p|734}}: {{Q|1207872}}. and {{Q|1207872}}: label: Cai (qualifier: transliteration system: Pinyin)
:::We could have to do the same with the given name (even though there may not be much to say about it. It is not like a traditional European given name that may have Wikipedia article because it is shared by many individuals, points to calendar-level saints etc. Essentially, it is just the string that was made up by the parents of Cai Yingwen so that it can be used as a name by their daughters) 
:::So, with current name-properties the only solution I see to get from {{Q|233984}} to pinyin = Cai Yingwen would be creating items about every name and surname and fetch the transliteration from them. --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 16:36, 15 July 2014 (UTC)
::::Yes, that could work to some extent, perhaps using {{p|734}} and {{p|735}} as qualifiers of {{p|513}}. I'm also thinking that a "name type" qualifier could be useful, because it would convey what to expect from the name (structure, order, etc). It is not the same to have a [[w:Spanish naming customs|Spanish name]] (given name + (optional names) + 1st surname + (optional particles) + 2nd surname), than a [[w:Chinese name]] (surame + name).--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:05, 15 July 2014 (UTC)
:{{P|734}} is to link to articles about the surname which may have a number of different spellings. I would expect these to be in the various language labels and aliases.
: The [[Wikidata:Property_proposal/Pending/3#Official_name_.2F_Name_.2F_Nom_.2F|Official Name Proposed Property]] is awaiting the monolingual datatype. We felt string was not appropriate. This is for the exact name of the person or item in their own script. If the item has official names in more than one language or the name has changed over time then this property can have multiple values. I agree that unofficial (or official) transliterations of these names would also be useful and [[Wikidata:Property_proposal/Archive/15#Transliteration_-_Cyrillic_.2F_Transliteration_.2F_Translitt.C3.A9ration_.2F_OTHERS|proposed a couple of properties for this]] but the proposal was not approved. One problem is that a transliteration property works best as a qualifier but you can't have a qualifier to a qualifier to tell you which transliteration system was used.

== Linked Data Interface ==

According to the [[Wikidata:Data_access | Linked Data Interface]] data about an item or property can be obtained from its URI, where the file format of the data can be selected through content negotiation by extending the URI with a postfix to indicate the file type, such as .json, .rdf, or .nt.
For example http://www.wikidata.org/entity/Q42.rdf.

However, the information contained in http://www.wikidata.org/entity/Q42.rdf basically contains only label-related data in all languages. What is missing now, are statements that relate this item to other items like "place_of_birth Cambridge". The corresponding wiki URI, i.e.https://www.wikidata.org/wiki/Q42, contains more informations - in particular the section about Statements.

Linking only to labels shouldn't be called "Linked Data" since the labels are dead ends or sinks, i.e. literals do not have properties that would point to other items. In other words, the network work of this "Linked Data Interace" consists of isolated islands, because the connecting properties are not rendered.

Either I am missing something here or the "Linked Data interface" should be supplemented with all the missing properties. [[User:Pingking|Pingking]] ([[User talk:Pingking|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:25, 18 July 2014 (UTC)

Long story short, from a Wikidata prospective, is persondata still useful or can it be dropped?  [[User:Bgwhite|Bgwhite]] ([[User talk:Bgwhite|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:29, 16 July 2014 (UTC)

::Before ripping the persondata out of all the enwiki articles, would it be possible to convert the persondata to a lua template that grabs it back from Wikidata?

== Class vs instance - Languoid ==

subclasses of languoid ([[Q17376908]]). Current links to that item: [[Special:WhatLinksHere/Q17376908]]. 

Now using languoid for data testing:
* Subclasses in autolist2: 159 [http://tools.wmflabs.org/wikidata-todo/autolist2.php?language=en&project=wikipedia&category=&depth=12&wdq=claim%5B279%3A(tree%5B17376908%5D%5B%5D%5B279%5D)%5D&mode=cat_no_wdq&statementlist=&run=Run&label_contains=&label_contains_not=&chunk_size=10000]

::: The question [[User:Delusion23|Delusion23]] asks is more interesting.  What do the statements below mean?
::::* [[:en:Biocide|biocide]]
::::: ''subclass of'' microorganism
::::: ''subclass of'' chemical substance
::: It means that any instance of biocide is an instance of microorganism [[:en:Logical_conjunction|and]] chemical substance.  In other words, it means that any biocide is both a microorganism and a chemical substance.  Having multiple ''subclass of'' statements means that the subject is a Boolean AND of the object of each ''subclass of'' claim.  It is the intersection, not the union -- see [http://www.cse.lehigh.edu/~heflin/IntroToOWL.pdf#14 page 14 here].  Thus those ''subclass of'' statements lead to the unintuitive and incorrect statement that something can be both a [[:en:chemical substance|chemical substance]] and a [[:en:microorganism|microorganism]].  Chemical substance and microorganism are disjoint; anything that is an instance of both classes implies an inconsistency (a falsehood) among our statements.
::: This example from Delusion23 indicates that we need a way to express union -- i.e. Boolean OR.  We should do this in a way that is easily [http://www.w3.org/TR/owl-ref/#unionOf-def compliant with W3C standards] and the fact that {{P|279}} has the semantics of rdfs:subClassOf.

:: [[User:Micru|Micru]], unsurprisingly, I think something closer to Semantic Web standards would be best.  The limited UI makes that difficult, but the closer we can align to W3C standards like OWL and Manchester syntax the better.  
:: For example, the "type of statement" qualifier prototyped in the links above casts &forall; as "mandatory statement" and &exist; as "one of these".  I would prefer to use "only" for &forall; and "some" for &exist;, as Manchester syntax does.  ''[http://webont.org/owled/2006/acceptedLong/submission_9.pdf The Manchester OWL Syntax]'' has a great overview, including design considerations and implementations in popular ontology editors like [http://protege.stanford.edu/ Protege].  The Protege UIs shown there would be a good thing to work towards, but, of course, developing a suitable UI for complex statements would likely take over a year.  Qualifiers are probably the best option we have.  
:: I was originally inclined to suggest using the generic ''applies to'' qualifier for this.  However, section 1.2 of the paper linked above describes a common misreading of quantifiers that we should be careful to avoid (and not facilitate): 
:: {{quote|Coupled with the problem of containing cryptic symbols, the syntax for restrictions is a prefix syntax. That is, the restriction  quantifier precedes the role/property name and optional filler. It has has been observed that this can lead users to initially read restrictions incorrectly.

Similarly, oxygen and isotope of oxygen would be equivalent classes.  If you disagree, then please suggest an example of a subclass or instance of atom that is not also one of isotope, or vice versa, or a subclass or instance of oxygen that is not also one of isotope of oxygen, or vice versa.
::::: Thus, a better way to model isotopes is as the ChEBI ontology does, for example "oxygen-18 ''subclass of'' oxygen".  ChEBI notably does not state "oxygen-18 ''subclass of'' isotope", but I think would could reasonably diverge from ChEBI here, which would enable retrieving the result set "isotope of oxygen" by querying "x rdfs:subClassOf oxygen AND x rdfs:subClassOf isotope".

::{{Ping|Tamawashi}} If a class has no instances, then it's equivalent to the bottom concept, whose only interest in a model is to be the bottom concept. The empty class, nothing, said differently. <Isotope> is not the bottom concept, it is a class of concept whose <Oxygen-18> is an instance of.

::: That is not correct, [[User:TomT0m|TomT0m]].  The most widely-cited ontology in the world, [https://scholar.google.com/scholar?hl=en&q=gene+ontology Gene Ontology] (GO), has no explicitly-declared instances, but none of its classes are nothing.  See for yourself: download [http://protege.stanford.edu/ Protege], open the GO ontology from the URL http://www.geneontology.org/ontology/go.owl, go into the 'Entities' tab, and then the 'Individuals by Type' tab.  You will see no instances; there are no instances defined for any classes in Gene Ontology.  
::: In fact, none of the ontologies in the OBO Foundry -- which GO is an example of, and which together are probably the main driver of OWL development -- have any instances.  This derives from observation that:
::: {{quote|The ontologies in OBO are designed to serve as controlled vocabularies for expressing the results of biological science. Sentences of the form 'A relation B' (where 'A' and 'B' are terms in a biological ontology and 'relation' stands in for 'part_of' or some similar expression) can thus be conceived as expressing general statements about the corresponding biological classes or types. Assertions about corresponding instances or tokens (for example about the mass of this particular specimen in this particular Petri dish), while indispensable to biological research, do not belong to the general statements of biological science and thus they fall outside the scope of OBO and similar ontologies as these are presented to the user as finished products.| ''[http://genomebiology.com/content/6/5/R46 Relations in Biomedical Ontologies]'', Barry Smith et al., 2005}}
::: This is likely what Tamawashi meant in saying "Classes don't necessarily have instances."  Subclasses of an isotope like oxygen-18 obviously have instances -- e.g. an atom of oxygen-18 floating in your room -- but those instances fall outside the scope of Wikidata.  Like any of those OBO ontologies used throughout biomedical research, the fact that Wikidata does not have any items about instances of oxygen-18 does ''not'' mean that oxygen-18, being a leaf node in a concept hierarchy, needs an ''instance of'' statement to avoid being inferred as nothing, i.e. <math>\bot</math>, the 'bottom concept' from description logic, i.e. owl:Nothing from the Web Ontology Language.
::: Claims like "oxygen-18 ''instance of'' isotope" are incorrect, per Semantic Web conventions as defined in OBO and other ontologies and the philosophical definitions of class (type) and instance (token) discussed in papers like ''Relations in Biomedical Ontologies'' and ''[http://ontology.buffalo.edu/medo/isa.pdf The Role of Foundational Relations in the Alignment of Biomedical Ontologies]''.

:{{Ping|Emw}} I still think you are dead wrong on this, and just one analysis of your query ''"x rdfs:subClassOf oxygen AND x rdfs:subClassOf isotope"'' to prove this : let's say isotope is an equivalent class of atom Then a reasoner could substitute the query to ''"x rdfs:subClassOf oxygen AND x rdfs:subClassOf atom"''. Then as any instance of oxygen is also an instance of atom, then the second member of your query is redundant, and your query is x rdfs:subClassOf oxygen. Which by the way can get any subclass of oxygen, not just isotopes.
: On the classes with no instances : I was talking of instances in the real world, not of instances in this database. 
: ''Claims like "oxygen-18 ''instance of'' isotope" are incorrect'' They are useful, and I think saying ''CheBi does not do this but I think we can'' makes you out of the line to say this. Your source does not do this for a reason, you can't make them say something they do not do, and then because of something they did not do make me say something incorrect.

<span id="Emw_query_without_inference"></span>
:: [[User:TomT0m|TomT0m]], the claim "oxygen-18 ''instance of'' isotope" is incorrect not because ChEBI doesn't make it, but because it would contradict ChEBI and the usage of ''instance of'' and ''subclass of'' throughout all of the most widely used biomedical ontologies.  The particular statement "oxygen-18 ''subclass of'' isotope" is not in ChEBI, but it would not contradict anything there.  
:: Given statements like "oxygen-18 ''subclass of'' oxygen, isotope", the queries to do what we'd want are straightforward:
::* Get ''only'' classes like oxygen-17, oxygen-18 and oxygen-19:
:::: SELECT ?subject WHERE { ?subject rdfs:subClassOf oxygen . ?subject rdfs:subClassOf isotope . }
::* Get all subclasses of oxygen and isotope:
:::: SELECT ?subject WHERE { ?subject rdfs:subClassOf* oxygen . ?subject rdfs:subClassOf* isotope . }
:: Note that the only difference between those queries is the asterisk (*) that appears after rdfs:subClassOf.  The asterisk enables computing transitive closure in SPARQL.  As we see, it is very straightforward to disable inference to get the desired result set.  Of course, many users presumably won't be directly writing SPARQL queries, but exposing some control in a user-friendly query UI like "Enable inferencing" would get the same result.
:: So we see that we can maintain compatibility with existing major ontologies and preserve a consistent meaning for ''subclass of'' while also enabling easy retrieval of things like oxygen-18. [[User:Emw|Emw]] ([[User talk:Emw|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:16, 20 July 2014 (UTC)
::: {{Ping|Emw}} You claim that we break compatibility with other ontologies, that's absolutely wrong. I don't add any inconsistency. I claim this way of doing, relying on non transitive queries is incorrect and non robust because it is non robust to inferences : the query does not work at all if we actually make the logical inferences. So a reasoner, who will make the inferences, with the same query, can not retrieve the actual isotope classes. And the whole point of beeing logically sound is to make inferences : our models have to be inference robust : you give us a query who ''works'' from your criteria without using inference as well, I ask you to provide a query that works with inferences turn, ie. with a real reasoner who will, him, make the inferences. This is a keypoint to good modeling : not rely on a set of conventions on how we built the model, but rely on the actual axioms : to a reasoner, there is no difference beetween a ''subclass of'' we actually put in Wikidata database and a ''subclass of'' relations he inferences, obviously : he can just logically safely add it to the set of facts. And if to classes are equivalent, then the set of facts he can infer grows a lot, or became smaller : he can safely forget one of the classes. Which totally breaks the query. Your query does not meet the ''inference robustness'' model criteria. And there is no point in using really strongly defined languages like OWL and carefully written ontologies if the whole point is not to use logics on them, this would be a really big contradiction in the way we build things. Your ''subclass of'' usage here does not make sense : it's so obvious isotope classes forms a metaclass : that is logically sounds, does not break any major ontology as the don't model the <isotope> concept itself ... Your {{Oxygen-18|subclass of|isotope}} is not backed by an ontology, that's a fact, whereas a class of classes is no precedent, is logically sound and achieves inference robustness. It's therefore useful and a natural way to model things. 09:10, 21 July 2014 (UTC)
{{Ping|Emw}} With "''Classes don't necessarily have instances.''" in my reply to [[User:TomT0m]]'s "''What are the instances of <isotope> if isotope is a class ? Just name one.''" - I meant exactly what I wrote, this had nothing to do with the scope of Wikidata, specifically all classes in the "abstract object"-tree have no instances and all instances should belong to some specific tree, probably physical object. [[User:TomT0m]]'s statement seemed to imply if something is a class it must have an instance, and his later comments at least for me, had more indications of thinking that I find no proof for, e.g. ("''If a class has no instances, then it's equivalent to the bottom concept, whose only interest in a model is to be the bottom concept.''" - philosphy is a bottom concept?). There are more funny statements: [[Q9121]] - atom 1) instance of molecular entity 2) subclass of matter 3) part of matter, molecule. I changed [https://www.wikidata.org/w/index.php?title=Q9121&diff=145022075&oldid=144704493]. What the relation to matter is (part or subclass), I have no time to decide right now.

::I align with Emw's statement that ''Claims like "oxygen-18 instance of isotope" are incorrect''. Correct would be: "oxygen-18 (one atom) instance of oxygen-18 (representation of all oxygen-18 atoms)".
::I also align with TomT0m statement that ''isotope is NOT an equivalent class of atom''. They are different generalizations of atomic occurrants.
::And also Tamawashi is right, we should start from the very bottom and then build up, NOT the other way round. 
::FIRST we have something, then we decide what it is, and depending one its characteristics it can belong to several categories. The problem here is that we don't have an item that represents "instance of one atom that it is also the instance of one isotope of oxygen-18 that is also instance of matter".

:::The mostly easy ones are probably done now ;) (though there are still quite a few left). Most items I fixed were items where multiple Wikipedia links about different places were within the same item. Easy items to fix were disambiguation pages about places in USA or at least having an English article (or German as well in my case). There you could compare census data or various geodata IDs from the Wikipedia articles to sort this out which Wikipedia article belongs to which item. Places/location infoboxen were also useful to compare the various Wikipedia pages in a structured way.

== Use of Wikidata content in Wikipedia so far ==

Hello, since I just started using Wikidata, for me the question arises, how widely is content from Wikidata used in Wikipedia pages yet? {{unsigned|Alepfu}}

:{{ping|Alepfu}} {{ec}} From the looks of the results of [[w:en:Wikipedia:Requests for comment/Wikidata Phase 2|this RfC on enwiki]], it's appropriate to modify existing infoboxes to permit Wikidata inclusion when there is no existing English Wikipedia data for a specific field in the infobox, but it's inappropriate to use Wikidata in article text on English Wikipedia. So, Wikidata's not widely used on WP yet. --[[User:AmaryllisGardener|'''<span style="color:#E0115F">Amaryllis</span><span style="color:#74C365">Gardener</span>''']] <sup>[[User talk:AmaryllisGardener|'''talk''']]</sup> 15:23, 21 July 2014 (UTC)

== first draft for Main page redesign ready for review ==

Hello again,

thanks for everyone who left feedback on the [[Wikidata_talk:Portal_Redesign|Main page redesign planning page]]. As promised, I've put together a first draft for the new Main page at [[Wikidata:Portal_Redesign/draft]] and would love to hear your comments and suggestions - please leave your feedback on the talk page.

Major changes include the following:
* moved language links down the very bottom of the page (currently they eat up a lot of important real estate at the top of the page)
* updated the "quick links" at the top of the banner/header (currently we just link to Statistics)
* added in a visual right at the top of the page - this is just a placeholder and could either function as a banner OR a rotating/dynamic slideshow (see [[voy:Main_Page|Wikivoyage]] for an example of a main page with both a banner and slideshow)
* added in other images and screenshots; updated link for "Wikidata in action" item to one in Reasonator that is more visually appealing
* added a new section, "Learn about data," that will ideally communicate what structured data is to those who don't already know (note: supporting content is still under construction)
* added a new section, "Discover," with the intention of highlighting and/or featuring tools, applications, queries, WikiProjects initiatives, showcase items, etc.
* removed "Use Wikidata on your wiki" section (it's important content but I don't think necessary to have on the main page, at least not at this stage in the project)
* merged "News" and "Staying up-to-date with development" sections together
* re-named "Contribute" section to "Get involved" - got rid of some of the links and clustered them together to make it a more manageable list
* made "Welcome!" section one column that takes up half the page instead of one that spans the entire length of the page
* made all sections one colour - green. This was just easier to work with as I moved sections around to different places but I thought I'd leave as is while collecting feedback

Just a note - the placeholder image at the top ([[:File:Wikidata_POTW_Candidate_11_(Plain_Map).JPG]]) comes from [[Wikidata:Picture_of_the_week]] - other ideas for infographics or images that would make good banners are more than welcome. While I like the placeholder one and think it's both visually appealing and relevant to conveying some of what Wikidata can do, it also does look very similar to the Wikivoyage banner. 

Looking forward to your comments. -[[User:Thepwnco|Thepwnco]] ([[User talk:Thepwnco|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:01, 21 July 2014 (UTC)

: The draft of the main page is a step in the right direction. I have three pointers. Firstly, like snipre mentioned the map picture is neither relevant nor helping the overall look of the page. Secondly, I´m not getting the point of the arrows between the links to Introducing Wikidata, Project chat, etc. Personally I would just put each of those links to their own line. Thirdly, I would swap the placements of the discover and get involved boxes. At least at my current resolution (1024x768) the placement of those two boxes create a big area of whitespace. Also, the position the discover box is at currently seems to be in a prominent place. I don´t really get why, since a minority of users are interested in the technical side of things.--[[User:Snaevar|Snaevar]] ([[User talk:Snaevar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:09, 22 July 2014 (UTC)

In normal page view, [[:en:Tin Can Cathedral]] shows a link to the Danish (dansk) page [[:da:Blikdåsekatedralen]] and vice versa, which seems good.

However, English seems to be available from [http://da.m.wikipedia.org/wiki/Blikd%C3%A5sekatedralen#/languages the Danish mobile view].

== Help with moving task forces to WikiProjects ==

Hi all,

I'm putting the call out for folks to help move/rename their task forces as WikiProjects. I'm asking because right now we are using both names in a seemingly arbitrary way and it is important to keep this consistent so as not to confuse people (in fact, this issue came up as something that should be discussed on [[Help:FAQ]] when I polled the community about sources of confusion when using Wikidata).

This issue was previously discussed on Project chat about a year ago (see [[Wikidata:Project_chat/Archive/2013/07#Rename_.22task_forces.22_to_.22project.22|here for the discussion]]) when it was proposed to rename task forces as WikiProjects because of the naming conventions of other sister projects (i.e. "WikiProject" is the term used on Wikisource, Wikipedia, etc.) and because the term "task force" was not a concept easily translated into other languages.There was also a [[Wikidata:Project_chat/Archive/2013/07#Rename_.22task_forces.22_to_.22project.22|bot request]] for assisting with this process but it appears it was decided in the end that we should just move task forces one by one. 

For those wanting to help, I recommend that something like "XX task force" be renamed to "WikiProject XX". The WikiProject should then be removed from [[:Category:Task forces]] and added to [[:Category:WikiProjects]]. 

I will take on moving [[Wikidata:LGBT_task_force]] and am happy to edit appropriate Help pages to reflect and document this change, but need help with the rest. Please let know if there are questions or concerns related to this proposal. Thanks. -[[User:Thepwnco|Thepwnco]] ([[User talk:Thepwnco|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:12, 18 July 2014 (UTC)

== Wikinews Sitelinks (Phase 1) ==

Greetings everyone!

As planned Wikinews will be the next sister project supported by Wikidata. We're starting with language links again and will later enable data access. Phase 1 is currently scheduled for August 19th. Depending on how that goes the next phase will scheduled. Coordination is happening at [[Wikidata:Wikinews]] and it'd be awesome if you added your name there if you're active on Wikinews. We need people to act as local ambassadors to make sure everything goes smoothly.

Let's make this deployment even better than Wikiquote was!

:How will we deal with linking news stories and notable events? --'''[[User:Jakec|Jakob]] ([[user talk:Jakec|talk]])''' 19:23, 22 July 2014 (UTC)

:: Over at en.wn, I remember we discussed Wikidata.  Perhaps aspects of the discussion are slipping my mind.  My memory (however flawed it might turn out to be) is we generally didn't see much utility for it in mainspace; and from what I know of other-language Wikinews category spaces, they often have such disparate category hierarchies that the prospects didn't seem very promising there.

:: I'd be interested to know quite what is meant to be done.  To the best of my definitely limited knowledge Wikidata seems to be a vehicle of encyclopedic structure, while Wikinews is about as different from an encyclopedia as a wiki can get.  Just for example, our concept of [[n:WN:newsworthiness|newsworthiness]] is very different from Wikipedia's [[w:WP:Notability|notability]]; and Wikinews is usually more interested in covering under-reported stories (and otherwise unreported ones, via [[n:WN:OR|original reporting]]) than in covering the biggest stories of the day, which typically have less need of our coverage.  (Keep in mind, being involved with news, I'm ''supposed'' to be skeptical aobut everything; I'm also supposed to have an open mind, and with all the bad news in the world I surely need to stay open to a positive outlook.)  --[[User:Pi zero|Pi zero]] ([[User talk:Pi zero|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:15, 23 July 2014 (UTC)
::: I might mention, Wikinews categories quite often do not correspond, or correspond closely, to Wikipedia categories, as the very ''purpose'' of a news category hierarchy is different from that of an encylclopedia category hierarchy.  Sister-linking Wikinews categories tends to be highly customized, and likely to only get more so over time as we get around to various types of hierarchy upgrades we've been planning.  --[[User:Pi zero|Pi zero]] ([[User talk:Pi zero|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:39, 23 July 2014 (UTC)
== Forth and back conversions of items between class and instance ==

I changed instance to class [https://www.wikidata.org/w/index.php?title=Q19020&diff=144807340&oldid=141997427] then had a look into the page history to obtain a link for my edits and ..., just on 2014-07-01 [[User:Humatiel]] did the opposite [https://www.wikidata.org/w/index.php?title=Q19020&diff=141997427&oldid=128065895].

The editor did create a [[Wikidata:Database reports/Constraint violations/P279]], since the item was target of "subclass of" since 2013-08-06 [https://www.wikidata.org/w/index.php?title=Q8624&oldid=64476902], created by [[User:TomT0m]].

There are still 6000 unrooted subclasses listed at [[Wikidata:Database reports/Item classification]].

::{{Ping|Tamawashi|Micru}} Develop and make [[Help:Classification]] more visible ? It's a really important page imho. Even people like {{Ping|Emw}} seem to disagree with me on some topic like the type of the ''isotope'' class, after many discussions. I, (I speak for myself) am pretty confident I am at a point where I sorted this out and the instance/class/class of class scheme works pretty well for me and is really useful to model things in Wikidata, see many examples on [[Wikidata talk:Item classification]] of why I think this works and is useful. But we need to be really clear on that and not make that discussion over and over again. I'd like to make [[Help:Classification]] approved by community when it is ready for beginners and reasonably complete.
:: A constraint cannot do the job of explaining that to a user. {{Ping|Micru}} The abstract/concrete view is probably confusing. There is often several level of abstration : we divide concrete things like atoms in chemistry in classes of concrete things like "oxygen", who is a class of atom, and "oxygen-18", who is a class of atoms to, a class of oxygen more precisely. But we also use more abstract levels : isotopes for example regroups classes, not instances : we can say that oxygen-18 and oxygen-16 are isotope, but oxygen-18 is not a subclass of isotope. The definition of subclass is not "things that links abstract concept", it's more precise. <span class="mw-code" style="text-align:right; display: inline-block; padding: 0.1em;">[[User:TomT0m|TomT0m]] <sup>([[User talk:TomT0m|talk]])</sup> </span> 06:33, 16 July 2014 (UTC)

:::{{Ping|TomT0m}} It doesn't seem that you have sorted out so well the distinction, otherwise you wouldn't be saying that "oxygen-18 is not a subclass of isotope". My reasoning is as follows:
:::# There are things that happen in nature by themselves
:::# By being in sensory contact with differentiable things (instances) we create representations of them
:::# By observing repeated occurrences, we create models of these things (classes)
:::Now I apply the same reasoning to "oxygen-18"
:::# There are oxygen-18 atoms that happen in nature by themselves
:::# By being in sensory contact, in this case through devices, with distinct oxygen-18 atoms (instances) we create representations of them (instance:oxygen-18 [one atom])
:::# By observing repeated occurrences, we create models of oxygen-18 (class:oxygen-18 [represents all atoms of oxygen-18 that may exist] )
:::Usually I see very often the inverse reasoning, specially from IT people, who put the class first and ''that'' is totally meaningless.

:::: {{Ping|Micru}} : I have a discussion going on with {{U'|Emw}} on this very page about this. See in particular about the proposition of query by Emw built with the <isotope> class and my answer on why it does not make sense : if <isotope> is a superclass of <isotope-18>, then the <atom> class and the <isotope> classes are indistinguishable for a reasoner, he can substitute one with the other. And I think I took part in pretty much every discussion about class/instance relationship and how they are implemented in the semantic web. I argumented and proposed to use the ''metaclass'' concept : <isotope> is a class of concepts whose instances are classes such as <isotope-18>, who exists as an entity in the human conceptualisation. What a human call an isotope is a class of atom. When we say ''oxygen-18'' is an ''isotope'', in common language, we don't say ''every oxygen-18 instance is an isotope''. Otherwis the whole ''isotope'' concept is useless compared to the ''atom'' concept. The <isotope> concept by itself is useful because all atoms in an isotope class have the same numbers on nucleons. We have an ''isotope'' concept because this property is shared by a big numbers of important classes of atoms, we can regroup in a set : the set of all isotope classes, which is NOT the set of all atoms at all. I backed up by citing the french Wikipedia's definition of the <isotope> concepts which says exactly that : ''an isotope is a class of atoms who share the same numbers of nucleons''. In short, in Wikidata we do not model reality only, we also model how human models reality. Which is a real thing too somehow. <span class="mw-code" style="text-align:right; display: inline-block; padding: 0.1em;">[[User:TomT0m|TomT0m]] <sup>([[User talk:TomT0m|talk]])</sup> </span> 09:12, 16 July 2014 (UTC) 
::::: {{Ping|TomT0m}} if the "the <atom> class and the <isotope> classes are indistinguishable for a reasoner" it is not because the classing, it is because they do not contain enough information to make them distinct enough. We need to translate the definition in human language (''an isotope is a class of atoms who share the same numbers of nucleons'') into ontological language (for instance, [https://test.wikidata.org/wiki/Q532 like this], but it could be done better).

But this concepts still do not map the ''isotope'' concept as all the kinds of isotopes types of all the atom types.

::"''The class of Oxygen-18 atoms is also an 'instance of:isotope' - a special type of class.''" I do not agree with this. An instance has to be either a material thing (continuant) or a unique process in order to be considered "instance", in other words it has to be something that exists "here" and "now". All the rest are class relationships, either as "subclass of" or "superclass of", that we don't use. The relationship between "the class of all Oxygen-18 atoms" and "the class of oxygen isotope (classification of atoms)" is a subclass relationship.
::I also don't agree with the book/novel, car/model examples. It was a mistake that we did on the Books task force that is spreading all over the place. It should be:

::Of course the terms "subclass of"/"instance of" are confusing, that is why it would be better to change them.

I agree and disagree with things [[User:Micru|Micru]] says [[#Micru_on_instances_and_classes|above]].  Foremost, I think changing the labels of P31 and P279 from ''instance of'' and ''subclass of'' to something else would be a bad idea.  Those labels have been established for over a year, have been used in academic publications and media coverage about Wikidata, and give an immediate, glanceable, conventional visual hook that illustrates a fundamental distinction used throughout the Semantic Web and philosophy at large to describe the nature of things.  Changing their aliases is OK, changing their descriptions with care is OK, but we should not change their labels.

I agree with Micru that "Moby Dick ''subclass of'' novel" is preferable to "Moby Dick ''instance of'' novel".  However, I disagree with the statement "Ford Model T ''subclass of'' car model".  Cars models are like biological taxa in that they are not physically instantiated.  Stating otherwise is a subtle mistake with significant consequences.  For example, if we say "{{Q|287723}} ''subclass of'' car model", then that entails the incorrect statement "{{Q|7756463}} ''instance of'' car model".  The Peetskill Meteorite Car is not a car model, it is a car (specifically, an instance of a Chevrolet Malibu).  Although Wikidata covers far fewer instances of car than instances of human, we should keep the application of ''instance of'' and ''subclass of'' consistent.  

And that is why the statement "oxygen-18 ''instance of'' isotope" is problematic.  Oxygen-18, cars, and humans are all types of [[Wikidata:Project_chat/Archive/2013/12#BFO_2.0_.28draft.29|material entity]].  Oxygen-18 is a type of isotope, car is a type of vehicle, and human is a type of ''Homo''.  Stating "oxygen-18 ''instance of'' isotope" creates an inconsistency in how we apply ''instance of'' and ''subclass of'' in cars and humans and all other physical things.  The fact that Wikidata will likely never have an item about an instance of oxygen-18 does not mean we shold state that oxygen-18 is an instance.  {{P|31}} is not simply what you use at the bottom of Wikidata's concept hierarchy.  For at least physical things, outside rare and straightforward usages of explicit metamodeling, ''instance of'' should only be used on items that have a unique location in space and time.

:{{ping|Emw}} I am glad that we are approaching postures. You might be right that it might no longer possible to change the labels of p31 and p279 without causing major disruption that we might want to avoid, but it worries me that some languages have departed from the canonical names and now they have come to represent different things (in German p31 is now "is a"), perhaps it will be enough making sure there is no confusion by explaining it better, or creating a tutorial.

:Just a minor correction regarding your car example. You say: ''if we say "{{Q|287723}} ''subclass of'' car model", then that entails the incorrect statement "{{Q|7756463}} ''instance of'' car model".'' I think we should examine deeper what a "car model" is. If we assume that ''a car model is a blue print for manufacturing an automobile with shared characteristics'', then the statement "{{Q|7756463}} ''instance of'' car model" is not incorrect, because we have a blueprint and from there we generate something that is an automobile. Of course the statement is ''less accurate'' than saying "{{Q|7756463}} ''instance of'' {{Q|287723}}", but still right. Same case as the example you gave me "{{Q|339}}<part of>{{q|1}}", which is not wrong, just "less right".--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 16:27, 19 July 2014 (UTC)
::{{Ping|Micru}} : this depends on the definition we use for ''car model''. Of course we can take a car, scan it and make a copy with a 3D printer, and our copy has a model : the original car. But it's not the common definition car manufacturers uses for ''car model''. We can define the <car model> item such that its correct wikidata use is ''a car model in the car manufacturing industry sense'', and we get rid of this ''correct in a loose sense'' notion that is ... Uncommon. Of course if there is a use for this definition we can create an item with this definition, but let's be precise and say that ''car that are 3D printed with some scanned car'' and ''car model in the car industry sense'' are different item.

:{{ping|emw}}. My understanding is that O-18 is general would be considered an isotope of oxygen but an individual molecule of O18 would not. That sounds remarkably similar to the Ford T case.
:As stated in [[#Issue with "instance of" for text]], I would argue for a similar analysis with novels. Novel is a subclass of text, and a text is, roughly speaking, an (immaterial) string of words and Moby Dick is best viewed as an instance of novel starting with "Call me Ishmael." It can be materialized in a book, an audio recording whatever, but those are instances of book, audio recording etc, not instances of novel. Of course defining a text as a string is a very crude approximation, but a definition of text would have to do with the us of words, the existence of a plot, etc. These are not features that a material object can have It implies that the class "text" is disjoint from the class "material object".--[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:35, 19 July 2014 (UTC)--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:30, 20 July 2014 (UTC)
:: Agreed with Zolo on the similarity with the <car model> and <isotope> discussions, that's why the instance/class/metaclass modeing 3 layer scheme I push other and other again make sense. "oxygen-18 {{instance of}} isotope" creates no inconsistency if we make clear that ''isotope'' IS NOT a class of physical objects itself, which can be made explicit in the ontology by a ''disjoint with'' statement beetween the <physical entities> class and the <class> class, so it is absolutely not a logical inconsistency. It's not an inconsistency with the Wikidata usage if we stop pushing the Token/class philosophical principle to newbies and start pushing a Token/class/metaclass principle which actually helps a lot into understanding how to model the world. Using {{subclass of}} as the only relationship beetween classes of tokens (I don't say ''instances'' intentionally) is a mistake and logical inconsistency source and should as a result not be pushed to users. So, {{U'|Emw}}, I think you should revise your way of thinking and starts thinking not ''car models'' as weird exceptions, but as the general case. When a scientific theory starts to have one exception scientists can be fine saying ''OK, that's a weird exception''. When there is a second, a third and so on they'll start thinking they need a {{Q'|Q689971}} <!-- Paradigm shift --> (paradigm shift) in their theories. I think token/class principle is such a paradigm who put our mind in a bottle, but everything is simpler if we break that bottle and shift to the token/class/metaclass paradigm. I provided several usecases for which this paradigm is useful, for me it's a compelling argument it's a solid paradigm, and more consistent than the "token/class with exception" you are proposing, who is unsatisfactory : if we got a 3 concepts principle which fits almost all wikidata, wrt. a 2 concept principle with 30 exception, the first has 3 concepts, the second 32 concepts.

::: [[User:Zolo|Zolo]], an actual atom of oxygen-18 is an instance of an isotope.  Instances of isotopes is what is measured in e.g. [[:en:Isotope-ratio_mass_spectrometry|isotope-ratio mass spectrometry]].  Thus the statement "oxygen-18 ''instance of'' isotope" is indeed inconsistent with how we use that property to describe things like humans, cars, and other physical things.  It is like saying "human ''instance of'' ''Homo''", not "human ''instance of'' taxon".
::: Some domains talk of types of types of things.  Biological taxonomy is one, but chemistry does so less, certainly in the way TomT0m envisions:
{{Hidden begin|title=Chemical elements (model by TomT0m)}}
[[File:Atom_classes.svg|500px]]
{{Hidden end}}
::: Which is easier for users to understand, the "atom type class" model proposed above or the one without a metamodeling layer, as used in widely-cited, professionally curated chemistry ontologies like [http://www.ebi.ac.uk/ontology-lookup/browse.do?ontName=CHEBI ChEBI]?  I do not think pervasive explicit metamodeling will ameliorate users' unfamiliarity with instances and classes.  I think it will bewilder them.  
::: ''Instance of'' and ''subclass of'' can be used for explicit metamodeling in a way that accommodates type-token distinction.  The usage seen in biological taxonomy is an example.  However, it is easy to do metamodeling in a way that breaks that useful distinction, as illustrated in statements like "hydrogen ''instance of'' chemistry element" and "oxygen-18 ''instance of'' isotope."
::: Doing so compels us to make absurd statements like "isotope is not a class of physical object" as [[User:TomT0m|TomT0m]] does.  As any chemist or high school student who has completed a course in chemistry will tell you, isotopes are physical objects.  Stating "oxygen-18 ''subclass of'' isotope" rather than "oxygen-18 ''instance of'' isotope" consistently applies classification properties in a way that does not compel us to paraphrase away basic scientific facts.

::::{{Ping|Emw}} I share your opinions to some extent. I think we should not use "instance of" for cross-domain relationships, but we can attempt to cross it with a different property, even if that departs from ChEBI. The way I envision it is like this:
{{Hidden begin|title=Chemical elements (model by Micru)}}

::::: [[User:Micru|Micru]], I think it is essential for Wikidata to use vocabulary from the wider Semantic Web.  The connection between Wikidata, the Semantic Web and ontology is that "class" is synonymous with "type" or "concept", as outlined in e.g. ''[http://ontology.buffalo.edu/medo/isa.pdf The Role of Foundational Relations in the Alignment of Biomedical Ontologies]''.  The conventional term for "classes of classes" like "taxon" or "car model" is metaclass.  Implying that classes are not types or concepts as your graphic above does would misalign Wikidata with most literature relating Semantic Web vocabulary to that from ontology.  Styling instances as "phenomena" and classes as "substance" is also highly idiosyncratic and would lead to even obscurer philosophical wanderings than those we currently see on Wikidata.  

::::: Metamodeling in the domain of chemical elements seems generally extraneous and unhelpful.  What makes "atom" a class and "isotope" and "element" metaclasses?  How do "chemical substance" and "physical object" fit in; are they class or metaclasses?  As explained [[#Emw_says_isotopes_are_physical_objects|above]] in my reply to Zolo, isotope is clearly a class of physical object and individual atoms are also isotopes.  Why should I have to include ''nature of'' as outlined in your graphic (note: as presented it should be ''has nature'') rather than use ''subclass of''?  What is the precise definition of ''has nature'' -- in terms used by the Semantic Web, i.e. OWL?  Precisely how would it relate to P31 (i.e. ''instance of'', rdf:type) and P279 (i.e. ''subclass of'', rdfs:subClassOf)?

::::: I think it would be far simpler to say something like "oxygen-18 ''subclass of'' isotope of oxygen" for such classes of isotope.  We could then say "isotope of oxygen ''subclass of'' oxygen, isotope".  Alternatively, we could say "oxygen-18 ''subclass of'' oxygen, isotope", and consider "isotope of oxygen" to effectively be a query result.  Both of these approaches adequately model isotopes in a way that is consistent with major existing ontologies and does not pose compatibility issues with Semantic Web standards.

:::::: Brilliant paper, [[User:Emw|Emw]]! It brings many insights and I dearly recommend [[User:Zolo|Zolo]] and [[User:TomT0m|TomT0m]] to read it. I will do it again, and again. On a first read I found some gems:
::::::*inst: defined as bound to a specific time and space. An instance can be related to its class (a instanceOf b)
::::::*class: defined by its instances, which means that they can change in time. A class can be related to its upper class (b subclassOf c)
::::::*set: a timeless entity, idealized class, not bound to time and space. A set or a class can be related to a set (b is_a d)
::::::The definition of what I called "nature" is what they call "is_a". Please, do notice the differences with "subclassOf" as cleverly explained in the section "Classes vs. Sets". I can go further and say that "is_a" is equivalent to "type" (well, they also say it in the paper), and "taxon rank" is a subproperty of "is a". 

::::::Coming back to my drawing, yes, you are right, it is wrong, I'll try again:
{{Hidden begin|title=Chemical elements (interpretation of FMA paper)}}
[[File:Atom_instances_classes_types_2.svg|500px]]
{{Hidden end}}

::::::That is my interpretation of the provided paper, with the nomenclature stated in the paper. True that for atoms it looks quite redundant (although here we wouldn't use classes), however it models accurately the relationship between classes-metaclasses and between metaclasses themselves. To use subclassOf for both purposes is missleading and brings to many confussions and long discussions as we are seeing. I hope we can all reach the same interpretation and consider it both acceptable and practical.--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:18, 20 July 2014 (UTC)

<span id="Emw_is_a_equals_subclass_of"></span>
::::::: [[User:Micru|Micru]], that paper formally defines ''is a'', a foundational property in major ontologies like the Gene Ontology (GO), ChEBI and others.  It is referenced as the basis for ''is a'' and ''part of'' as discussed in [http://genomebiology.com/2005/6/5/r46 Relations in Biomedical Ontologies], a very widely-cited, classic paper in modern ontology.  That paper establishes the link between "is a" and the language of the Semantic Web: "A has_subclass B = [definition] B is_a A." -- in other words, "A rdfs:subClassOf B" equals "A is a B".  This equivalence between BFO/OBO's ''is a'' and RDF/OWL's ''rdfs:subClassOf'' is noted in the [https://docs.google.com/document/d/1_lKE8kAmFfi12_TBrDs1COMDPXDQGByKJZAaBwW5xVM/edit draft BFO 2.0 release documentation] and clear from RDF/OWL exports of GO, ChEBI and other ontologies among the [http://www.nature.com/nbt/journal/v25/n11/full/nbt1346.html Open Biomedical Ontologies].

::::::: The relation between classes and sets is a recurring topic in these discussions on Wikidata.  Classes are treated essentially as sets in the Semantic Web.  The foundational ''subclass of'' property is even symbolically represented with the symbol as "subset of" -- i.e. ⊆ -- in the [http://www.w3.org/TR/2004/REC-owl-semantics-20040210/direct.html#axiom-interpretations Interpretation of Axioms and Facts] in the OWL Direct Model-Theoretic Semantics specification.  The relevant OWL specifications address this by noting that a class is distinct from the "extension" of that class.  

::::::: It is interesting how your subsumption hierarchy (the "class tree") of atom in your interpretation of the FMA paper is virtually identical to that used in ChEBI.  See e.g. the "graph view" visualization in the ChEBI model of oxygen-18 at http://www.ebi.ac.uk/chebi/chebiOntology.do?chebiId=CHEBI:33815&treeView=false#vizualisation.  Of course there is no mirrored subset tree, because ''is a'' is equivalent to ''subclass of''.  

::::::: The ChEBI ontology does not explicitly account for some things we may want to, e.g. isotopes.  One suspicion is that this is because all instances of atom are also instances of isotope, and vice versa.  However, we might be able to model the notion that "oxygen" itself is not an isotope -- while preserving consistency with ChEBI and those other widely used ontologies -- with an approach I outline [[#Emw_query_without_inference|above]].

:::::::: {{ping|Micru}} Thanks for the link. Some notes:
::::::::* It states that nothing can be both a class and an instance, and that conflicts with the latest OWL version. The current theoretical view appears to be that we should distinguished between the statements about the item seen as an instance of X and those of the item seen as a subclass (seen as a instance of species, gorilla beringei is an endangered species, seen as an subclass of animal, it is hairy).
::::::::* Nothing in the theoretical part of the article says that an instance must be localizable in time and space. They indeed allude that they should in the conclusion, and for highly empirical topics like biology, it is certainly true that most instances have a location, but that would be an empirical fact, or a methodoligical advice, not a formal imperative (yes 
:::::::* You are misreading the paper, it does not say that classes are defined by its instances, quite the opposite: contrary to a set, a class "survives the turnover in its instances".
::::::::* I like their idea that contrary to a set, a class does not have 2<sup>n</sup> subclasses (actually it think we can say that "subset" is a subclass of "class" with some special features, except that it would sound a bit odd to include the empty set and singletons in the list of subclasses). --[[User:Zolo|Zolo]] ([[User talk:Zolo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 07:56, 21 July 2014 (UTC)
::::::::{{reply to|Emw}}. Ok, if individual molecules are isotopes, then clearly it is fine to call 018 and subclass of isotope. --07:56, 21 July 2014 (UTC)~
::::::::: {{ping|Emw}} first of all some term equivalences:
::::::::: * what OWL calls "extension of a class" = what FMA calls "class"
::::::::: * what OWL calls "class" = what FMA calls "set"

::::::::: For the particular case of chemical elements I agree with you that there is an "almost" 1:1 relationship between class-set (real atom vs conceptual atom), but not making this distinction is problematic for several reasons. The main one is the superposition of "natures" that an element has, which collapse into one as soon as we try to access experimentally (adding instances to) one of them (cf. [[w:wave function collapse]]). Only by avoiding to use the "isotope" set, they are able to keep an equivalence between "class" and "set". It is not a lie, they just don't consider all the range of possible truths.

::::::::: In our particular case, it would be perfectly fine to model chemical elements considering an equivalence between subclassOf = is_a because we don't instantiate them. For the classes that we do instantiate then metamodelling (making a distinction between class and set) is useful (taxonomy, cities, literary works, etc). But that of course forces us to juggle with properties, when by using two distinct properties (FMA-subclassOf, FMA-is_a), would remove all obscurity from our model.

::::::::: The other reason to make the distinction is to avoid mixing up "extension of a class" and "class". If we use OWL-subclassOf for both cases we might arrive to the weird conclusion that a person might have the permanent nature of being an actor (!). That means that we accept instantiating permanent concepts as impermanent instances, with all the inconsistencies and headaches that it brings.

::::::::: For these reasons my recommendation is to abide to the FMA definitions (instanceOf=phenomena, subclassOf=OWL-"extension of a class", is_a=OWL-"class"). This will guarantee compatibility with all existing and yet to exist ontologies, because we'll be able to cast both subclassOf and is_a to the same external ontology property (if they have so defined), or to distinct properties (if they have so defined).

::::::::: {{ping|Zolo}} They refer to "''[http://ontology.buffalo.edu/smith/articles/SNAP_SPAN.pdf SNAP and SPAN: Towards Dynamic Spatial Ontology]''". Basically: SNAP=continuants (permanent) and SPAN=occurrants (impermanent). According to this model, yes, you can instantiate a permanent class (set), but not as an impermanent entity!--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 08:26, 21 July 2014 (UTC)
::::::::::{{ping|Micru}} That is true, but that seems to work well as long as we do not need to assume that everything is a SPAN and SNAP.

{{od|::::::::::}}
{{ping|Zolo}} Your tree puts again together sets and classes (the "entity" you put on top cannot be both "abstract" and "real"), and as showed before that is problematic. Here there is another one:
* unlocalizable entity (concept, set)
** qualities: physically identifiable characteristics (shape, color, etc)
** attributes: abstractedly identifiable characteristics (the "is_a"-ness)
** entity: the concept that something might exist either as unlocalizable or as localizable entity
* localizable entity (phenomenon, instance)
** event
** material object
{{ping|Emw}} I'm sorry that I'm not following OWL conventions :( I realize that the definition of entity is self-referential... this is not my personal preference, it is just how nature appears to me... very weird... :-/ I also realize that there are more "unlocalizable entities" that only apply to living beings, but it is better to focus on this first.--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:57, 21 July 2014 (UTC)

::: {{quote|The rdfs:subClassOf construct is defined as part of RDF Schema [RDF Vocabulary]. Its meaning in OWL is exactly the same: if the class description C1 is defined as a subclass of class description C2, then the set of individuals in the class extension of C1 should be a subset of the set of individuals in the class extension of C2.

::: And reviewing the definition of classes in OWL:
::: {{quote|In general classes are used to group individuals that have something in common in order to refer to them. Hence, classes essentially represent sets of individuals.

::: The equivalence between BFO's ''is a'' relation and OWL's ''subclass of'' is used, for example, in the chemistry ontology ChEBI: 
::: {{quote|All database entries are now 'is_a' classified within the ontology, meaning that all of the chemicals are available to semantic reasoning tools that harness the classification hierarchy...

::: Reviewing further, ''[http://ontology.buffalo.edu/medo/isa.pdf Role of Foundational Relations]'' formally defines ''is a'', and  ''[http://genomebiology.com/2005/6/5/r46 Relations in Biomedical Ontologies]'' harmonizes that definition with Semantic Web standards from the W3C by clearly defining the equivalence of ''is a'' and ''subclass of''.  The equivalence is made explicit in the [https://docs.google.com/document/d/1_lKE8kAmFfi12_TBrDs1COMDPXDQGByKJZAaBwW5xVM/edit?pli=1 BFO 2.0 release notes].  The three aforementioned works are led by the same individual and the latter two are produced by the same group.  The equivalence is used throughout the world's most widely used biomedical ontologies.
::: Nowhere in any of those works is the discrepancy you assert between ''is a'' and ''subclass of'' alluded to.  The ontologies in question that use the equivalence of ''is a'' and ''subclass of'' in practice, Gene Ontology and ChEBI, are maintained by content experts with advanced degrees and deep experience in chemistry, computer science, philosophy and ontology.  If your concern with the discrepancy between sets and classes because of [[:en:Wave function collapse|wave function collapse]] were warranted, don't you think they they would have noticed that, and raised that issue somewhere in a publication?  Do you really think that's why they don't explicitly have an "isotope" concept in ChEBI?  I suspect the cause was much more mundane.  A discrepancy between ''is a'' and ''subclass of'' would directly contradict what that network of researchers have clearly stated in multiple major publications and spent over a decade building.

::::{{ping|Emw}} the last message by [[User:TomT0m|TomT0m]] about intensional vs. extensional definitions clarifies quite well the class-set duality paradox that was besetting me. Seen under that light, yes, I agree on the equivalency between subclassOf and is_a, not because any researcher or produced bible says so, but because it is possible to reconcile that duality the same way it is done in quantum physics. Any entity has thus an "existential state:indeterminate", that can collapse into "determinate existence" -when seen from the perspective of its instances (extensional view), it can represent "extension of that class"-, or into "determinate non-existence" -when seen from the perspective of its abstract meaning (intensional view) it can represent an ideal set, non-localizable in time or space. It is not necessary to declare this explicitly, because the presence or absence of instances already serves that purpose.

----
{{ping|Zolo|TomT0m}} Continuing expanding the reasoning that I was exposing below, I realize that it is very similar to the 3 layer model that TomT0m is talking about:
#there is an idealized class of something, that at the same time is an instance of itself (see my example with the natural number "5" below)
#there is a class of all real occurrences of that class
#there are instances of the class of the real occurrences

So applying it to the case of "a novel" 
#there is the idealized class of a novel, and the class is abstractedly equal to their instances (all thoughts about a "novel" are both a class and an instance, even if they happen with different material substrate)
#there is a class of all real occurrences of the class abstract novel
#there are instances of the class of real occurrences of the former

Now the problem is to find what is the relationship between 1-2 (I hope we can all agree that the relationship between 2-3 is clearly class-instance). For 1-2 is not that clear, because it seems that this relationship is neither of instantiation, nor of classing, but of abstraction. 2 is an materialization of 1, 1 is an abstraction of 2. It would be interesting to see if there are precedents of these kind of relationship in the literature (pun intended :P).--[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:34, 20 July 2014 (UTC)zz
: I don't follow you, and I think numbers are a bad example: they are already exists as a datatype in Wikidata, so I think we are fine using properties like {{P'|length}} or cardinality to use them. Otherwise clearly we are fine with the set membership/subset relationships for classes here : Natural numbers are a subset of numbers in the most general sense, "5" is a member of that set, so I'd be happy with {{Type|number 5|natural number}} for Wikidata, and {{SubType|Natural numbers|numbers}}. I don't think it's interesting to go deeper here and enter philosophical or math foundation like number set construction problems.
: Otherwise I think it's interesting to keep with {{instance of}} for linking classes to metaclasses because it is user friendly imho : in french, {{instance of}} is labelled ''nature'' (by the way {{u'|Emw}} the english labels are not really supposed to be a reference here so I'm fine with changing the english labels, there is aliases and definition for precisions) and it's pretty intuitive to say that the nature of Porshe 911 is car model imho.

::{{ping|TomT0m}} The pun was because I was giving an example with a "novel", which is also literature... but yes, I agree with your statement, we have to be consistent mainly internally, because if we try to follow every source, the most we can aspire to achieve is inconsistency.
::Ok, so we have ''metaclasses'' that are abstract concepts, ''classes'' and ''instances'', and your proposal is to use p31 to link both metaclasses-classes and classes-instances... wouldn't that put metaclasses and classes in the same tree?

On the other hand, I like '''a lot''' the label "nature" for the relationship between classes and metaclasses, but I would prefer another for the relationship between classes-instances, perhaps "occurrent of", "phenomenon of" or even keep "instance of"?

::: [[User:Micru|Micru]], "occurrent" is a direct subclass of entity in BFO, the upper ontology used in the world's most cited ontologies.  It translates roughly to "event"; it is disjoint with "continuant", which includes things like material and immaterial entities.  A complete rendering of BFO's class hierarchy is shown [[Wikidata:Project_chat/Archive/2013/12#BFO_2.0_.28draft.29|here]].  Thus changing ''instance of'' to ''occurrent of'' wouldn't be ideal.  Changing it to ''phenomenon of'' would make Wikidata very idiosyncratic in the Semantic Web.  The label ''instance of'' makes it clear that that property is based on Semantic Web conventions and the description logic that undergirds it.  These disciplines use one property for instantiation -- instance-class classification -- and one property for subsumption -- class-class classification.  It also makes it clear that the subject is an instance, whether that instance is an occurrent, a phenomenon, a human or a car.

I lost some part of the discussion, but I'm not sure we are fine with some useful definitions of set theory : the so called set ''intentional definition'' concept : a set is defined by a property of their instances. This is an equivalent to ''class expressions'' in OWL : a class is then defined not by its instances, but by properties of its instances, see {{Q'|Q1026899}} <!-- Intensional definition -->. 

This notion is useful to understand my proposition (which is not an invention of mine btw, it's a used definition) because it fits : clearly <Oxygen-18> and <Oxygen> are both classes of atoms. But what makes one an element-class and the other an isotope-class is that we use different criteria in the intensional definition : in the element classes like <Oxygen> or <Hydrogen>, we use the property ''atomic number'' of atoms in the intensianal definition formula (class expression in OWL), and in the other one we use the number of nucleons of the atom. Now imagine we want to class, as in ''automatic classification'' in computing with learning machines or other mechanisms, ie. define a set of ''classes'' and put every class expression into some of those classes, clearly the ''chemical element class expression'' and ''isotope class expression'' definitions would become very handy and have a lot of sense. Imagine, in the sense of OWL punning, the classes item (<Oxygen-18> or <Oxygen>) becomes some kind of ''reification'' ([[en:Reification]] the senses on computer science for example, or in knowledge representation, I'm also aware of uses in logic), in some sense, is the act to treat something abstract like the other object in a model to be manipulated as the other basic objects of the model).

Then we got something very solid here : metaclasses are classes of reified (OWL2 allows this) classed using properties of their intensional definitions (as classes). We're fine with the class/token principle if we don't forget that reifications are not real world objects. It's natural to a lot of people (ie. this is exactly how the <isotope> concept is defined by french Wikipedia : ''an isotope is a {{Q'|108149}} <!-- (no label) -->'', nuclide is a type of atom. (seems the article have been rewritten since I read it the last time, it did not have the ''nuclide'' concept in it ! By the way {{Ping|Emw}}, were you aware of this concept ? How does this fits in your views ? It seems to me that it is exactly the ''atom type class'' concept I proposed ! Once more something I did not know but prove my reasoning solid, there is a word for this concept. So Wikidata has to be able to deal with this. Just merged the items.) I don't have time to rewrite all, but feels like a victory to me. <span class="mw-code" style="text-align:right; display: inline-block; padding: 0.1em;">[[User:TomT0m|TomT0m]] <sup>([[User talk:TomT0m|talk]])</sup> </span> 17:00, 22 July 2014 (UTC)

== General question regarding subjects of important works ==

Hi I have been updating the items for people portrayed by Frans Hals, but I notice that it's sometimes a bit blurry whether an article is about the person portrayed or about the creative work (in this case, a portrait). To solve these, I have been creating two items, one for the person and one for the creative work. See Aletta Hannemans: [[Q16859703]] and [[Q17275957]]. With the portrait painting, I want to link to the pendant (for which I use the property "part of"). With the person, I want to link to her family (and soon also, the house where her brewery was). My question is, does she really need two items in this case? I want to be sure before I do more of these. Thanks in advance.

And  [[User:Multichill|Multichill]], here is another related question (working with the Rijksmuseum dataset):  In [[Q17419089]] this person item, I pick a detail of a painting to illustrate the person. I link to the detail file on Commons with property "image", and then I say that it is "part of"  the item for the painting. Is this enough?

I am looking for a Wikidata page that describes the aims of the Wikidata project for Wikipedia interlanguage links. What should it provide?

::Thank you, YMS. I think one hint is missing there. Wikidata interlaguage links serves readers of Wikipedia and not the data-aspect. Readers should find informations from the article in other languages. It is not necessary that two linked articles have the equal lemma. Nevertheless you should aim this. But it is sufficient to find similar informations in the articles. Since the interlanguage links moved to Wikidata people think they should give different Ids to slightly different article-lemmata. But that is not the sense of the interlanguage links. And it was not the way interlanguage links were provided in Wikipedia. Thus the reader does not find informations in other languages. -- [[User:Tirkon|Tirkon]] ([[User talk:Tirkon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 04:15, 26 July 2014 (UTC)
:::Tirkon, this is by design. The whole point of Wikidata is being specific, while often on Wikipedia various concepts are bundled into one article. In languages where there are two meanings for one word, you will often both meanings in one article, whereas in languages where these two meanings have two words, there are two articles. Neither language is more "correct"  than the other one, but Wikidata has two items, only one of which can be linked in those languages which have "bundled" their concepts into one article.

::::Thank you, Jane. I know the problem with not matching articles or two lemmata in one article. What do you think about the following approach in case of doubt how to group the articles together under same ID:  "The aim of Wikidata interlanguage links is to provide informations in as much as possible other languages. The aim is not to group exactly the equal lemmata. That means: If grouping similar lemmata together (same ID) instead of dividing them into different groups (different IDs) produces considerable more interlanguage links in all languages than another grouping, then this grouping should be chosen. -- [[User:Tirkon|Tirkon]] ([[User talk:Tirkon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:54, 26 July 2014 (UTC)
:::::I think you need to just start in and see how it goes. At first I felt the same as you, but I changed my mind. I disagree with your purpose for interlanguage links. Not "as much as possible other languages" but "in other languages". Wikidata will help to start splitting articles that are now bundled in Wikipedia. I don't mean that Wikipedia should become a dictionary, but I do think we should see some of the really long articles on Wikipedia start to split into more manageable chunks that can be read comfortably on a mobile device.

::::::There are cases where every Wikipedia groups topics together but Wikidata still needs to split these topics into different items. This happens when statements about one topic are not true about the other item. If we need separate items to make statements then we create separate wikidata items, even if none of those items will ever have it's own independent wikipedia article.

== Wikidata:Requests for comment/Admin conduct policies ==

Since recently some admins arbitrarily, without coverage by policies, used their right of blocking a contributor, I created [[Wikidata:Requests for comment/Admin conduct policies]]. [[User:Tamawashi|Tamawashi]] ([[User talk:Tamawashi|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:28, 27 July 2014 (UTC)
:Not a real RfC; just a way to cause trouble. The questions is poses are already policy. I recommend you close it/request it for deletion or an uninvolved admin closes it/deletes it. It's just a case of 'I was blocked, I want the admins involved to be desysop'd immediately because the community has no policy regarding it!' [[User:John F. Lewis|John F. Lewis]] ([[User talk:John F. Lewis|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:34, 27 July 2014 (UTC)

What makes an RfC a "real RfC"? Do you disagree with the initial text:
----------------
Admins should only use their specific admin rights if the usage is covered by policies.

Admins should loose their specific admin rights if they violate that rule.

The guideline(sic) named "[[Wikidata:Blocking policy]]"(sic) should be upgraded to a policy.
----------------
?

This '''It's just a case of 'I was blocked, I want the admins involved to be desysop'd immediately because the community has no policy regarding it!'''' is defamation.

:It's not defamatory. Also the first line basically says we can't; block, protect, revision deletion etc. because we have no policies regarding them.

== Wikidata:Requests for comment/Blocking policy ==

I started [[Wikidata:Requests for comment/Blocking policy]] with the initial text:

---------
There is a page named "[[Wikidata:Blocking policy]]" which is labeled as "guideline".

* There are admins that claim that Wikidata has no blocking policy.
* There are admins that claim there is one. 
* Admins refer blocked users to that page, as if it would be a policy.
* Admins refer blocked users to that page as if it contained all rules for blocking. 
* Other admins refer blocked users to [[Wikidata:UCS]] "use common sense".

The proposal is either
# to make this page a policy or
# to rename this page to "[[Wikidata:Blocking guideline]]" or 
# to rename this page to "[[Wikidata:Blocking]]" and mark as an essay.

It seems that in wp:az, there can be two articles about the same topic, one in arabic alphabet and the other in latin alphabet. The result is this : [[Q4361548]] and [[Q12846577]].

: Interesting and useful gadget I think! But somehow loading localized labels does not work in all cases fine though. I just tried with German language for the person gadget, when I click on "Update labels" in the "General" tab, sometimes it loads the German labels for the bottom three properties and sometimes it loads the German labels for the other properties in that tab. And sometimes it does not display any labels at all, just the property number.

== "Uncle" in Turkish and Bosnian ==

It appears that Bosnian and Turkish may have different words for an uncle who is your mother's or your father's brother. The "mother's brother" uncle links are at [[Q6041134]] on their own but the "father's brother" links are with the other links for "uncle" in general at [[Q76557]]. Should they be separated out? And if so, what would the labels be in languages that just have one word? Perhaps "paternal uncle" and "maternal uncle"? Cheers.

== Wikidata Main page needs a banner and you can help! ==

Hi all,

As you may know, I'm currently working on planning and implementation of a new Main page for Wikidata. One idea to already come out of the redesign process is that the Main page should be more visually appealing. 

To that end, I am wanting to get together an awesome banner (or choice of banners) for the top of the Main page and am inviting you all to share your ideas and submissions. We are looking for something that represents Wikidata and the idea behind the project; is eye-catching but also easily translatable; and is freely licensed CC-BY (or equivalent). 

If you think you know how to communicate what Wikidata is through images or have an eye for graphic design, navigate over to [[Wikidata:Portal_Redesign/Banner]] where I've already started brainstorming designs and to learn more about the open call for submissions. Please add your proposal (or a link to it) to the talk page.

We hope to have our banner or banners ready for use on the new Main page in two weeks from now so please have all submissions in by 19:00 UTC on August 11th 2014. Feel free to leave questions here or on my talk page.

Cheers, -[[User:Thepwnco|Thepwnco]] ([[User talk:Thepwnco|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:03, 28 July 2014 (UTC)</br>
ps.  thanks to those who have already [[Wikidata_talk:Portal_Redesign/draft|provided feedback on the Main page redesign]]—for those who haven't, there is still time to do so!
== Be generous in what you accept... ==

When entering the value of a property, it should be possible to paste in one of these formats:

== Song Contests ==

I'm quite new to Wikidata, and find it really interesting! I have been working on different song contests, such as the {{Q|10162}}. Those contest should be about songs competing, but now the artists performing the songs are listed as {{P|710}}. How can both the song and the artist be structured under such a song contest? Example: {{Q|3720656}} performed the song {{Q|3739483}} during {{Q|10162}}. //[[User:Mippzon|Mippzon]] ([[User talk:Mippzon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:07, 28 July 2014 (UTC)
:You will need to use qualifiers for the other information about each participant. We have {{P|17}} and {{P|1358}} but I don't think we have a property we can use for the song so you may need to [[Wikidata:Property proposal|propose a new property]]. New properties are more likely to be approved if you can show that they can be widely used.
:Alternatively you could have 'Participant' link to the song and use {{P|175}} to link to the singer, or propose a new property for competitions where the entrants are not people.
:To search for existing properties put P: at the start of the search term or [https://www.wikidata.org/w/index.php?title=Special%3ASearch&profile=advanced&search=&fulltext=Search&ns120=1&redirs=1&profile=advanced go here]

:ESC's intention was to be a competition of composers and song writers. I agree that listing the performers as participants (which is the current state) is wrong. Formally, ESC can also be regarded more like a competition between the members of the European Broadcasting Union. However, just as there may be more than one composer of a song, there may be more than one broadcasting organization representing a country. Consequently, to me, it would make most sense to list the countries as participants and add all detailed information as qualifiers. Proposal:<br />STATEMENT: {{P|710}}: {{Q|35}} / QUALIFIERS: represented by (or some already existing property I am unable to find once again): {{Q|1164334}}, represented by: {{Q|1616154}} (in my opinion, the broadcasting organizations would need to be listed as those may not be the same in every year), song (yet again unable to find a correct existing property): {{Q|3739483}} (that item should feature the composer), {{P|175}}: {{Q|3720656}}<br />One thing I noticed along the way is that from the item {{Q|3739483}} one could get the impression that it represents the specific combination of the composition with the performing artist (kind of saying "Emmelie de Forest's version of 'Only Teardrops'"). With such a schema, there would be no need to list the performing artist as qualifier above. However, since a composition might very well be performed by someone else as well, items should not feature specific combinations of song and artist (think of some Jazz-Standard having been performed by thousands of artists); (if {{Q|3739483}} is performed by some additional performer, (s)he should be listed in that item as performing artist as well.)<br />Okay, that would cover the most basic information. But what if you are asking for trouble and want to capture all the scores - the individual ones assigned by each country, not just the final scores? Well, then I would suggest to basically forget all the above and just use the following statement (which sounds quite ugly though):<br />STATEMENT: {{P|710}}: {{Q|4809098}}. (Alright, maybe there is a more appropriate property, but it is about finding such...)<br />{{Q|4809098}} would act as container for all Denmark at the Eurovision Song Contest 2013 related information. Points, artist, song and whatever. In my opinion, that would be the most sane and flexible solution. [[User:Random knowledge donator|Random knowledge donator]] ([[User talk:Random knowledge donator|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 09:14, 30 July 2014 (UTC)

:: Yeah, I think that structure with the country as {{P|710}} is a good choice. Then it's easy to add appropriate qualifiers under each country. But is it not possible to add {{Q|7366}} as a qualifier? //[[User:Mippzon|Mippzon]] ([[User talk:Mippzon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:45, 30 July 2014 (UTC)

::: The structure with the country looks good at first sight, but if you want to track all points, e.g. how many points Sweden awarded to Denmark, you run into trouble and the second solution - simply linking to a "container" item - would be far less of a hassle - the syntax is not as expressive and obvious though...<br />{{Q|7366}} is an item which can be used as value in statements. What we need is a property. There is a property {{P|51}} which has an alias "song" - but that is of data type "Commons media file". We need a property of type "Item", so an item - {{Q|3739483}} - can be linked.

Like {{Q|3720656}} has property "performed song" and all the songs she performed listed? //[[User:Mippzon|Mippzon]] ([[User talk:Mippzon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:53, 30 July 2014 (UTC)
== Difference ==

== Wikidata @ Wikimania 2014 ==

Hey everyone,

As per Lydia's request, I have compiled a list of all Wikidata-related events currently planned for Wikimania. With it, also includes a list of Wikimedia Deutschland staff going who work on Wikidata. Please go up to them, say hi and thank you for their awesome work! You can see the page at [//wikimania2014.wikimedia.org/wiki/User:John_F._Lewis/Wikidata_Events the Wikimania 2014 wiki].

===Alternative===
{{ping|Jasper Deng}} As an alternative to more rules, I would like to suggest to start something similar to [[w:Wikipedia:Teahouse|the Teahouse]] to welcome new users, to encourage them to participate, and to help them integrate into our community. Better to welcome new friends with a cup of tea than with spiky laws and regulations! --[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:15, 24 July 2014 (UTC)

:From your response it seems obvious that I am not an experienced editor. Suffering a lack of communication is therefore the ticket.. ?

::Where did I say that? New editors will of course have to obey it, but it's the experienced editors that need these policies. Not that new editors won't have to follow them.

:::{{ping|Jasper Deng}} If it is for experienced good-intentioned editors, then it is even worse than I originally thought. Our goal to build a healthy community should be that everyone here can become best friends, not arch-enemies. Cultivate weapons, and you will have war. Cultivate dialogue and the wish to understand each other's opinions, and you will have peace and harmony even when disagreeing.

:::Yes, it is much easier to have a trigger that you pull and your problem sort-of-disappears, but it never works that way, it will start a dinamic of oppression and mistrust from which it will be very hard to escape. Have you heard about Wikipedia's editor decline and ever wondered why?
:::{{quote|''When asked to identify Wikipedia’s real problem, Moran cites the bureaucratic culture that has formed around the rules and guidelines on contributing, which have become labyrinthine over the years.''|[http://www.technologyreview.com/featuredstory/520446/the-decline-of-wikipedia/ The Decline of Wikipedia]}}

:::On Wikimania last year there was also a very interesting talk by a Polish researcher:  ''[https://wikimania2013.wikimedia.org/wiki/Submissions/Collaborative_or_Conflict-Driven%3F_Conflict_Trajectories_on_Wikipedia Collaborative or Conflict-Driven? Conflict Trajectories on Wikipedia]'' (there is also a youtube video). Dariusz recommends to create the role of facilitators, users who help to bring perspective and peace, in order to avoid entrenchment and hate speech.

:::In Wikidata we should hear to wise advice and strive for community peace as the ultimate goal. If there is any policy that we should adopt, that is the [https://wikimania2013.wikimedia.org/wiki/Submissions/Adopting_friendly_virtual_space_policy friendly space policy] (I recommend watching the whole video), so that if anyone feels hurt or under harassment there will be always someone to hear them. We should act as a shelter for all our members, no matter if they are sometimes right in some issue, or wrong, because our contributors are the most valuable jewel that we have.

:::That RFC speaks too much of edit warring and punishment, but too little of peace and conciliation. To learn the language of peace takes time and community effort, but the fruit that will give us is much sweeter and lasting. I kindly request that this RFC is stopped and instead we draft collaboratively one from scratch where everyone can feel represented.

::::After reading your comment more, I also will say that the main problem with policies is an ''excess'' of ''rigid'' policies that the community neglects to amend over time.

:::::In my opinion this RfC only addresses "surface problems", but not root causes. When we arrive to the situation of blocking an user, that is already too late. We should instead focus on how the problems arise, and address those situations first in a patient, and friendly manner.

::::::I didn't intend to frame it as anything ''but'' consensus building. Phase 1 is ''intended'' for the preliminary discussion. The root cause ''is'' our lack of written agreement on policies. This RfC in fact ''requires'' the collaboration of the community on agreeing on them. You have so far said many things saying that "rules are bad" but you have not given any evidence for how new policies could not possibly prevent further incidents. After all, content disputes are perennial parts of a wiki and I frankly do not get how a teahouse would help preventing any of them from getting out of control.

re. an IRC channel; we have one - #wikidata. It is a channel ran by the community not the staff (sure, Lydia might be the channel contact) the chanops are all community members (mostly Rschen and I) and sure the development team piggy-back off their development part in the channel but that is because the development and community need to be one. The lack of user interaction in the channel is the communities fault for not using it. If we moved the development team into #wikidata-development, please tell me how that would boost interaction? It won't. [[User:John F. Lewis|John F. Lewis]] ([[User talk:John F. Lewis|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:18, 24 July 2014 (UTC)

:John, you describe the status quo and then blame the community for not using it. Given the amount of work related traffic and given that answers to questions go unanswered, I find that I hardly ever use the IRC channel. Something new is happening all the time and it is hardly ever relevant to people not working on the Wikidata code. 

:When development uses its own channel and when admins talk about not so sensitive stuff in the open channel, we will get more relevant traffic to the users of Wikidata.

::Administrators have a separate channel only for the purpose of discussing private matters such as revision deletions. We only use it for that and a way to communicate with other administrators asking for 2Os. Maybe Wikidata is a project which doesn't have to use IRC everyday then, that is fine. What is not fine is you always going around saying we don't have one. We have one, whether the community use it or not is their choice and their fault, not the development team's fault for using an empty channel instead of creating a new one. [[User:John F.
