== "Search" does not return the obvious one ==

When I Search, WD does not return the most obvious hit (i.e., the one I am expecting). Searching "Horse" (lang=English) [https://www.wikidata.org/w/index.php?search=&search=horse&title=Special:Search&go=Go&searchToken=etap27xqfbw7164h8irewvh3j], the top-3 results are:
:Vale of White Horse (Q1540110)
:Dark Horse Comics (Q373933)
:horse breed (Q3745054)

Why is not {{Q|Q726}} in top?

(I'm sorry if this is a repeated point, but ay me searching this page makes it recursive ;-). And also consider the date). - [[User:DePiep|DePiep]] ([[User talk:DePiep|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 22:33, 1 April 2018 (UTC)

== Classifiying knots ==

I checked some knot items and all used {{P|31}} to classify them. Based on one of my earlier questions about use of subclass vs instance of, is it correct to suggest that knots should use {{P|279}} instead? Because for any knot there could be many "instances".

== Conflict with separate Wikidata items vs.  single, combined Wikipedia articles about distinct works ==

Hi. Is there an established way how Wikidata and Wikipedia handle cases where the Wikipedia article covers several distinct works while standard practice over here is to create separate items for each of those? How are Wikipedia templates on such articles able to pull data about these works from separate Wikidata items?

The reason I'm asking: [[User:InMontreal]] alerted me to a problem [[User talk:Kam Solusar#manga vs anime|here]]. I was adding external IDs for movies and TV shows and came across some anime shows that didn't have their own items yet. When it comes to mangas/light novels and their anime/film/game adaptations, standard practice on Wikipedia (all/most language versions) seems to be to cover them all in one big article. Which means that currently our items in that field are usually a wild mix of statements pertaining to mangas, light novels, animes, video games, etc, and also include external IDs like {{P|345}}, {{P|1267}} and {{P|1985}} for specific works. So I created several new items for anime series and moved all respective IDs and statements for these shows to the new items.

But it seems on various Wikipedias such IDs might be removed after they have been transferred to Wikidata, so the link templates no longer contain them and simply pull the ID from Wikidata. So when you split them into separate items for each work (as is usual on Wikidata), those IDs are also moved to those items and are no longer accessible for Wikipedia templates. Infoboxes also suffer the same problem of course. I hope there's a solution besides just telling Wikipedians to deal with it themselves. {{Ping project|Movies}} --[[User:Kam Solusar|Kam Solusar]] ([[User talk:Kam Solusar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 01:56, 24 March 2018 (UTC)

::So it seems the "solution" is indeed "just telling Wikipedians to deal with it themselves" :-/ . I mean, it probably isn't a bad idea for Wikipedias to modify their infoboxes to pull their data from other items if needed. But who's going to tell them, since it doesn't seem like the infoboxes on the affected articles are able to do that at the moment?
::So, as the guy who created the new items and moved the statements over, I guess I have two options: a) tell two or three dozen Wikipedias they now have to change their link and infobox templates to deal with the changes to a few items I chose to make on Wikidata - although to them, there wasn't really a problem with the status quo that needed fixing. And then I'd probably have to justify the changes in many languages that I don't even speak. Or b) undo my edits and give the whole topic a wide berth in the future - in the hopes that someone with a lot more time, energy and patience will stumble upon this problem and is willing to deal with it. --[[User:Kam Solusar|Kam Solusar]] ([[User talk:Kam Solusar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:04, 26 March 2018 (UTC)

::::I'm not sure that's the best way to handle such situations, since Wikipedians might see it as Wikidata changing/breaking things without giving Wikipedia a warning. And especially on smaller Wikipedias, it might break stuff for a long time until people figure out what happened and find someone to fix the templates. One of the problems [[User:InMontreal]] pointed out on my talk page is, that when you move all the statements and IDs to a separate item, there's no indication on the main item why they were removed and where to find them now. Or people might just assume that they are missing and try to add them back (which happens often with external IDs harvested from link templates). I didn't know a good way to indicate "for information about the anime that is also described in the linked articles, see QXXXX", though I just found {{P|4969}} which looks like it might do the job of at least having visible links on the main item.
::::Though I'd prefer if there was some kind of outreach to point out the problem to affected Wikidia communities and how to handle it, so not every single community has to stumble on the problem and try to figure it out for themselves. --[[User:Kam Solusar|Kam Solusar]] ([[User talk:Kam Solusar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 00:36, 29 March 2018 (UTC)
:::::Sorry but it is not as if Wikidata is new or that practices like these are new. There are plenty of things Wikipedia does that does not make sense from a Wikidata perspective. The problem is also that communication is often broken by Wikipedians insisting on no Wikidata. So outreach sure.. But who is to do this?

::::::@[[User:Kam Solusar|Kam Solusar]]: The correct way to do this is to create an item for the franchise like {{Q|642}}, link the article to it and add the anime, manga, light novel, OVA etc items with {{p|P527}}.
::::::Then Wikipedias can create modules to retrieve the correct identifier. --[[User:Thibaut120094|Thibaut120094]] ([[User talk:Thibaut120094|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 03:14, 31 March 2018 (UTC)
::::::{{Reply|Thibaut120094}}: Seems more like a workaround (as the articles' primary topic seems to usually be the manga/light novel series, not a franchise), but if that's the current solution for these cases, guess I'll use it. Though I'm not really looking to take on the task of creating items for all the works covered by those artices/items myself (especially since I don't know all that much about about manga franchises)... --[[User:Kam Solusar|Kam Solusar]] ([[User talk:Kam Solusar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:58, 3 April 2018 (UTC)

:::*If there were cases where this seemed to work before, it might worth looking into them in detail. It's likely that they were probably broken in one way or the other, but people just didn't notice (e.g. publication date of a film displayed in the infobox about a print version). To work correctly, infoboxes that are used in articles combining several topics need to do a check on P31 of items they attempt to use data from. <br/>--- [[User talk:Jura1|Jura]] 06:33, 29 March 2018 (UTC)
:::::Yeah, some might have shown false information for quite a while without anyone realizing it (or they realized it and didn't find someone who could help fix the problem). Checking the P31 statements helps, but I imagine there could still be some problems with items that have multiple P31 statements and in cases where there's more than 1 infobox for the same type of work on one page (i.e. a franchise with more than 1 tv show or videogame). --[[User:Kam Solusar|Kam Solusar]] ([[User talk:Kam Solusar|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:58, 3 April 2018 (UTC)

== Edinburgh Research Archive - thesis collection data ==

Hi all, after a hiatus we are returning to look again at importing data on the [https://www.era.lib.ed.ac.uk/ Edinburgh Research Archive]'s thesis collection into Wikidata. The ERA has over 20,000 thesis records so we are looking to get the modelling correct - once agreed our Library Digital Scholarship Developer {{ping|ChaoticReality}} can proceed with the import reasonably quickly. For a refresher on what we originally discussed in November 2017 in Wikidata's Project Chat [[Wikidata:Project_chat/Archive/2017/11#Importing_thesis_data_from_the_University_of_Edinburgh_Research_Archive|is here]] and the Google document with the data model we originally proposed [https://docs.google.com/document/d/1RrKu4Xku26Tt2qkdsbGLbU9D_X08XVtHOgDwI2AAiiM/edit is here].
<br>
'''3 questions arose from our discussions last time:'''
#There are 24 (approx) thesis types in the collection. If I create a ''thesis' item for each type  as was suggested e.g. '''ChM Master of Surgery thesis''' then is it to be described as P31 ''Instance of'' a masters thesis? OR ''P279 subclass'' of a masters thesis?
#Prize essays are a whole other kettle of fish. They seem to be described on Wikidata as ''scientific article'' but they can be on any subject I believe and sometimes become thesis dissertations and sometimes not. I wonder if it would not be better for prize essay to have its own Q number? What do you think? A reference to one with some explanation here: [https://books.google.co.uk/books?id=Ak45AQAAMAAJ&pg=PA500&lpg=PA500&dq=%22prize+essay%22+edinburgh&source=bl&ots=YlXk7nKfBL&sig=RarL7VuhZ0roNrp6MqOn7HAuiiI&hl=en&sa=X&ved=0ahUKEwjo-eDcysXXAhWP0RoKHUPDB4oQ6AEIPTAF#v=onepage&q=%22prize%20essay%22%20edinburgh&f=false here]. [[w:User:Gweduni|Gweduni]] has more info on the Prize essay distinction if you need further info.
#Finally, Should we also update existing items that don't yet have links? For example Doctor of Philosophy (Q752297) is a subclass of Doctoral Degree (Q849697) but Doctor of Education (Q837184) is not. So should we include statements to make that connection?
<br>For info, all the below are theses.
<br>Subsets of thesis: doctoral, masters, ‘other’.
<br>'''Doctoral (Level 12 on the Scottish Credit and Qualifications Framework – the highest level)'''

Any pointers, gratefully received. Many thanks, [[User:Stinglehammer|Stinglehammer]] ([[User talk:Stinglehammer|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:01, 28 March 2018 (UTC)
: 'P279 subclass' is correct. Instance should only be used for a specific thesis with a given title and author etc. If you find missing items or statements as you suggest, please add them as long as they make logical sense; wikidata is always going to be incomplete, it's up to us to help improve it!

I've numbered your questions:

# Subclass of; per Arthur
# {{Tq|"would not be better for prize essay to have its own Q number?"}} Yes, the maxim "be bold" applies
# yes.

(Gotta love Wikidata discussion threads. Sooooo much easier).

:::{{ping|ChaoticReality|Pigsonthewing|ArthurPSmith}} Ok 
Have created Wikidata numbers for the thesis types now and added on this [https://docs.google.com/spreadsheets/d/1NfOFpo25b8o-Amwrc52aFmjdb8rbOnsr1Qwp0NQ38Jc/edit?usp=sharing Google sheet]. Items in red are newly created thesis type items. Items in blue indicate there is a one item being used for two thesis types. i.e. Master of Literature (Master of Letters) and Master of Letters (Master of Letters) are both [[Q1907865]] so the master’s thesis is [[Q51283362]] for both. 3 questions cropped up again:
#Checking with [[w:user:Gweduni|Gweduni]] that he is happy with this or whether we should separate the two. Thoughts? 
#Prize essay now has its own Q number: [[Q51282441]]. Are we happy how it is described? Checking with [[w:User:Gweduni|Gweduni]] as to what would be an adequate description and statement type for a prize essay. 
#I’ve added that each degree type (e.g. Master of Surgery degree) is a subclass of master’s or doctoral degree etc. but there might be some extra tidying up needed – seems to be a real mix of instance and subclass statements being used to describe each degree entirely differently at present. What ''should'' be the main statement modelling/hierarchy we should be working with on these degrees do you think to keep things logical & consistent?

== Capturing provenance of food ==

Is there any property used to capture the region or more specific location where a particular food originates from? For example that a pasty originates from Cornwall? There is {{P|495}} but thats only for countries. There is {{P|1071}} but that seems more focussed on manufacturing rather than where a food product is originally from. Does this need a new property? [[User:Pauljmackay|Pauljmackay]] ([[User talk:Pauljmackay|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:11, 31 March 2018 (UTC)
: There are some claims like {{Q|782709}} {{P|361}} {{Q|47176}}, but maybe that's not quite the same thing. [[User:Ghouston|Ghouston]] ([[User talk:Ghouston|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:33, 31 March 2018 (UTC)

:{{ping|Pauljmackay}} - {{P|P2341}} is explicitly scoped to include "cooking style", so this would seem a good approach. Just be careful with {{Q|Q187495}} and {{Q|Q1419824}} ;-) [[User:Andrew Gray|Andrew Gray]] ([[User talk:Andrew Gray|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:53, 31 March 2018 (UTC)
::{{ping|Andrew Gray}} - that seems like a good option except after adding it to {{Q|586591}} it flags an issue because the constraints on that property require it to be a {{Q|746549}}, which wont be true for all food products. Should the constraint be altered? [[User:Pauljmackay|Pauljmackay]] ([[User talk:Pauljmackay|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:22, 31 March 2018 (UTC)

:::{{ping|Pauljmackay}} yeah, I think that's the best approach - broaden the constraint a bit. As well as a cooking style we could have indigenously-identified prepared foods, basic foodstuffs, spice, drinks... [[User:Andrew Gray|Andrew Gray]] ([[User talk:Andrew Gray|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 14:39, 31 March 2018 (UTC)

:Might also be useful to note foods etc that have a formally protected [[:en:Geographical indication]].  There's been an industry initative to produce a worldwide database of these ([https://www.ip-watch.org/2017/04/14/industry-group-nears-completion-list-geographical-indications-worldwide/ report]), and it looks like the database is usually live [http://www.origin-gi.com/i-gi-origin-worldwide-gi-compilation-uk.html here], though just at the moment it seems to have fallen off the net.  But here's [http://webcache.googleusercontent.com/search?q=cache:mirJMGVCFsIJ:www.origin-gi.com/i-gi-origin-worldwide-gi-compilation-uk.html+&cd=7&hl=en&ct=clnk&gl=uk Google's cache of the first page].
:Everything on the list probably ought to have an item, if it doesn't already.  Property {{P|138}} may also be useful.  [[User:Jheald|Jheald]] ([[User talk:Jheald|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:02, 31 March 2018 (UTC)
:There is {{P|1071}} with alias "location of origin" and "place of origin". Current label is more focused on manufacturing, but it was changed in 2014 from "place made", which was an original label in time of proposal. 
:We have a lot of items about {{Q|1565828}} and most of them use {{P|131}}, which is not appropriate in my view.--[[User:Jklamo|Jklamo]] ([[User talk:Jklamo|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:25, 3 April 2018 (UTC)

== Property with unproper type ==

Hello, I think the property {{P|P1461}} should be of type external identifier. [[User:Louperivois|Louperivois]] ([[User talk:Louperivois|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:29, 31 March 2018 (UTC)

== Academic writing: activity or type of work? ==

{{Q|4119870}} has been a confusing item since it has been created. Is this about the activity of writing academic works or is it a type of academic work? I can't read all languages. [[User:Sjoerddebruin|<font color="#325186">'''Sjoerd de Bruin'''</font>]] [[User talk:Sjoerddebruin|<font color="#325186">(talk)</font>]]  11:25, 2 April 2018 (UTC)
:I think Wikidata needs separate items for the type of work and the activity of writing such work. I would expect a Wikipedia article to cover both the activity and the work it produces (in fact, I think that it would be hard to separate them in an encyclopedic article).  For the sake of useful Interwiki links, I'd keep the article links on the existing work item and create a new linked item for the activity.  (For an interesting comparison, see {{Q|Q1193158}} [activity] and {{Q|Q1413406}} [work].) - [[User:PKM|PKM]] ([[User talk:PKM|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:09, 2 April 2018 (UTC)

== Improving the definitions of crafts ==

The Heritage Craft Assocation defines a "heritage craft" as "a practice which employs manual dexterity and skill and an understanding of traditional materials, design and techniques, and which has been practised for two or more successive generations" (see their [http://heritagecrafts.org.uk/redlist/ Red List]). IMHO most of the items that [[Special:WhatLinksHere/Q2207288|link]] to {{Q|2207288}} are occupations, not the craft (skill, practice) itself. So {{Q|19794820}} is a craft, a {{Q|328325}} is an occupation or artisan that practice that craft.

Also these crafts and occupations should be subclasses, not instances, along similar lines to my other recent questions :-) What do others think? [[User:Pauljmackay|Pauljmackay]] ([[User talk:Pauljmackay|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 16:41, 2 April 2018 (UTC)
:I agree on separation of crafts and craftspeople.  See {{Q|Q11642}} and {{q|Q3400050}}, {{Q|Q29167534}} and {{Q|Q21820569}}. These can be connected using {{P|P3095}}.  I am less certain about instances vs. subclasses.  I think <instance of> is perfectly appropriate for things like crafts and occupations.  If {{Q|328325}}  isn't an instance of an occupation, what would be? - [[User:PKM|PKM]] ([[User talk:PKM|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:54, 2 April 2018 (UTC)
:: Maybe [[Wikidata:WikiProject_Visual_arts/Item_structure#Types_of_visual_artworks|this overview helps]]? [[User:Multichill|Multichill]] ([[User talk:Multichill|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:52, 2 April 2018 (UTC)
::: On {{P|31}} versus {{P|279}}, a question I find is often quite useful is: can one imagine a specialist form of this activity or thing.  So one could imagine "Chinese fan-making" or "18th-century fanmaking" or "paper fanmaking", suggesting the activity should be a class.  As for the occupation, I am less convinced that one would identify "18th-century fanmaker" (ie a maker of 18th-century fans) as a distinct occupation, so I would be minded to keep it as an instance, unless/until a more specific instance gets created.  [[User:Jheald|Jheald]] ([[User talk:Jheald|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 09:41, 3 April 2018 (UTC)
:::: {{ping|Jheald}} thinking more on that aspect, I wondered if a sensible structure is that a stonemason (or whatever) is an instance of an "occupation" ''and'' a subclass of "artisan". So Joe Bloggs ''is a'' stonemason or artisan, but ''has an'' occupation of stonemason. [[User:Pauljmackay|Pauljmackay]] ([[User talk:Pauljmackay|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:33, 3 April 2018 (UTC)
::::: Except that, on Wikidata, Joe Bloggs ''is'' a {{Q|5}}, and stonemason is not a subclass of person. {{Q|1294787}} we identify as a subclass of {{Q|Q28640}}, in turn a subclass of {{Q|Q12737077}}; so making stonemason a subclass of {{Q|1294787}} makes it a subclass of {{Q|Q12737077}} as well. [[User:Jheald|Jheald]] ([[User talk:Jheald|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:20, 3 April 2018 (UTC)
:::::: {{ping|Jheald}} currently I see {{Q|1294787}} is an instance of {{Q|28640}}, so does that need changing to subclass? [[User:Pauljmackay|Pauljmackay]] ([[User talk:Pauljmackay|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:47, 3 April 2018 (UTC)
::::::: {{reply to|Pauljmackay}} Perhaps not: Reasonator says we have 489 instances of {{Q|28640}}, only 8 subclasses.  Passing this to the crowd, to see what anybody else thinks.  [[User:Jheald|Jheald]] ([[User talk:Jheald|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:52, 3 April 2018 (UTC)
:::::::: There’s discussion on this point on the talk page of {{Q|28640}}! which I would characterize as “unresolved”.  Personally, I like the distinction {{q|Q4220920}} = subclass and {{Q|Q222344 }} = instance. - [[User:PKM|PKM]] ([[User talk:PKM|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:38, 3 April 2018 (UTC)

Hello,
Is there a language set up for various languages? in particular bts and map-bms? Map-bms has its own wiki. I tried adding info to these languages, yet its not supported on Wikidata.

== Notification of Rapid Grant proposal for Wikidata QuickSheets expansion for P172 ==

FYI, I wanted to let you all know that I have submitted [[:meta:Grants:Project/Rapid/Theredproject/WikidataQuickSheets|a Rapid Grant proposal]] to further develop software that will semi-automate the process of moving data from Wikipedia to Wikidata. The tool is designed to be accessible to those without programming experience by using simple article lists to generate spreadsheets for human evaluation. This builds on work done as part the Art+Feminism campaign, which is detailed at our [[User:Theredproject/2018 Workplan|workplan]] but this grant is not for A+F related work. I welcome your feedback on the [[:meta:Grants:Project/Rapid/Theredproject/WikidataQuickSheets|proposal]]. --[[User:Theredproject|Theredproject]] ([[User talk:Theredproject|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:25, 3 April 2018 (UTC)
== Are empty categories allowed on Wikidata? ==

Hi all

I'm working on a way to record datasets that are being and have been imported into Wikidata and it will involve some use of categories. However some categories will be empty when the tool is published and then be populated later, and could possibly at some points be empty again. Are empty categories allowed on Wikidata? Is there a way to signify that even though the categories are currently empty they will be used in future? If someone comes and deletes the categories thinking they are helping tidy up it will break the tool and this is something I would very much like to avoid.

Thanks

:Liuxinyu970226's objection does not make much sense to me. "I oppose because they'll be eg Category:Articles for deletion since 2009 and who will look at them?" What? 1. They won't have such a name, and the name is largely irrelevant 2. no-one is being invited to dig through them: categories have other uses than being lists that people look through 3. no harm is adduced in your objection 4. we can make the assumption that JohnC is trying to do good things with them. What is not to like? Meanwhile they are not tracking categories - if I understand the rubric of that page correctly, nor are they Babel categories. Registering them as such seems pointless and damaging. I don't know the category system in wikidata well; I recall en.wiki has a "do not throw me away if empty" template designed for exactly the situation outlined by JC. So, perhaps I might ask for an articulation of credible issues that might arise from JC's proposal? --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:19, 31 March 2018 (UTC)

* I am the one who deletes most of the empty category items these days, mostly based on [[Wikidata:Database reports/to delete/empty category items]]. We have a couple of hundred new cases each week, due to Wikipedia category deletions that leave back empty category items here at Wikidata. Deletion of those items is not very complicated in any way, but it consumes quite some time if done properly.<br>Since the most important purpose to have categories linked to Wikidata at all is to provide interwiki links, empty category items appear indeed somewhat unnecessary and I'd prefer not to start with such exceptions. If however the community now comes to agreement that we should accepte empty category items for a while, I could try to avoid running into them (provided I have a list of affected items) while working down the queue. However, these kinds of exceptions do not scale at all, and I'd probably stay away from category deletions if a second editor requested something similar.<br>An alternative would be to create the categories already at Wikipedia and link them to the items; however, there is a comparable risk that some editor nominated them for deletion "because they are empty". Same problem technically, just that it had to be dealt with somewhere else... Not sure what to think of this :-) --[[User:MisterSynergy|MisterSynergy]] ([[User talk:MisterSynergy|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:35, 31 March 2018 (UTC)


{{ping|Tagishsimon}} {{ping|MisterSynergy}}, thanks very much, does the 'don't delete me, I'm useful' template (I think on Commons its called a maintenance category?) exist already? 

So to explain what I want to use them for, I want to create an updated version of [[Wikidata:Data_Import_Hub]] where each dataset has its own page because it is becoming popular and very crowded. The pages for each dataset would be organised by using some broad categories around if the dataset import is 'in progress', 'needs help' or is 'complete' and then split by some broad topics (copying the Mix n' Match topics) and then a few categories for things like data type (e.g spreadsheet or list). The user can then explore the datasets by running searches for more than one category at a time e.g all the 'in progress' datasets about 'art'. These searches would all be premade using cirrussearch and the user would just click the button. 

When the process first gets up and running a small number of the categories will be empty and its possible that some categories will be empty from time to time because there is nothing fitting that description e.g imports that need help. I just don't want categories to get deleted during this window which would break the system. In total the system would have maybe 30 categories and my guess is perhaps 2 or 3 would be empty from time to time.

There's a rough draft of the user interface at [[User:John_Cummings/Wikidata_Import_Hub_draft]] which may explain things a little better. 

Thanks

== Standardizing historic patents ==

I work on historic patents and would like to standardize our ontology for them here.  There are millions of them, and for those before 1900 no standard global source to search for them.  Wikidata can do that.  Is anyone else interested in working together on this?

Probably a patent item should have:
* instance of patent ([[Q253623]])
* country where filed -- but not necessarily a currently-existing country; e.g. in the German states before 1870 there were patent systems.  Presumably the WIPO code is appropriate to mark the country of a patent, but that would require some kind of property proposal. [[Property talk:P3068]]
* discoverer or inventor ([[Property:P61]]) -- there can be multiple inventors
* applicant(s) -- not always the same as the inventor(s), notably if a company filed the application, or the inventor died and someone else is filing
* title -- a string
* filing date is not the same as grant date; it would be good to store these distinctly because they have different historic meanings. The filing date is when the technological claim was made by the patent-filer, and the grant date is the date the government accepts and approves it officially.  Both have legal importance.
* Wikisource id should be used when a patent is transcribed there. it's infinite work but a good idea in some cases. Good text is not always available and Wikimedia can help.
* patent number -- a Wikidata standard for this exists: ([[Property:P1246]]) -- however format is restrictive, requiring format like US891393. Usually this works but in some historical cases there are letters in the 'number' (1BB##### in 19th century France, though possibly the 1BB can be left out), and there may be cases in which there is no proper number, so this item is optional but will be there in >99% of cases. Note that patent number in this format does not include year and so is not unique e.g. in Great Britain numbers were reused year after year.
* publication date, optionally -- historically this was sometimes later than grant date
* A standard naming scheme for the items is desirable in those cases that they are not named distinctively, e.g. by the title.  Something of this kind has been unambiguous in my research so far: Patent plus country plus year plus number, e.g. "Patent US 1906 821393"

: I've been wondering about that too. It makes sense that target of {{P|31}} for every item should be a subclass of something, i.e. it uses {{P|279}} (see [[Wikidata:Item classification#Classification in Wikidata|here]]), and it makes sense that every individual organism is an instance of some taxon, which is a class of organisms. Taxon items however generally avoid using P279, they use {{P|171}} to build the class hierarchy. P279 could be used in addition to "parent taxon", but then for many cases one would seem redundant to another, e.g. why would we indicate every species in some genus as subclass of "tree" (or some other organism), while this applies to all species in this genus. I see that using P279 instead of P171 [[Wikidata:Requests for deletions/Archive/2013/04/02#Property:P171|was considered in the past]], but P171 stayed in use, in my opinion, judging by the RfD, without much of a good reason. While P171 is a well-defined property, I don't quite get it how is this different from any other classification that works out more or less fine using P279, including for cases when an item is part of multiple classifications. And property label ('subclass') being homonymous seems to be of little importance, say, if English label isn't homonymous then it may be in some other language or vice versa, and I assume users would generally check the description before applying a property that they are unfamiliar with. Perhaps, in light of this tree issue and data model model in general, using P171 should be finally reconsidered? [[Special:Contributions/90.191.81.65|90.191.81.65]] 06:23, 6 April 2018 (UTC)
:: That discussion about P171 provides the right thing to set {{P|279}} to: the item for the nearest parent taxon. So {{Q|15978631}} can be a subclass of {{Q|171283}} and {{Q|149851}} a subclass of {{Q|14707792}}. That does make {{P|171}} seem redundant.

There are many items and categories already in Wikidata, but they don't seem to have subclass statements or be linked to each other. It's possible cleaning this up could be automated using Wikipedia categories as a starting place.  But that's not part of my skill set, and military insignia aren't my area of expertise or particular interest. So far I have not distinguished between the concepts "badge" and "insignia", since they seem to be interchangeable on Commons. My understanding is badge=physical object and insignia=symbol, but I don't know that the military use the terms in this way. Anyway, does anyone want to take on expanding this structure? - [[User:PKM|PKM]] ([[User talk:PKM|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:39, 7 April 2018 (UTC)

I would like to add the term "WoeKO" into the database. I have the history of the individual and links. How can this process work? {{unsigned|Woeko|8. 4. 2018, 05:49‎}}
:{{ping|Woeko }} please check out [[Wikidata:Notability]] and let us know if "WoeKO" meets the test.

::{{Ping|Pigsonthewing|Kam Solusar|Jklamo}}I noted a problem: if both the items have an {{P|856}} property linking to the same URL, there is a property constraint violation. What to do?
::Create a new property (renaming {{P|856}} in "official website URL") that links to the item representing the official website instead of the website itself?
::Or add {{P|805}} filled with the item representing the website as value of the {{P|856}} property inside the company item and change the property constraint so that it is allowed more than one item linking to the same URL, but only one without a {{P|805}} qualifier? --[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:43, 5 April 2018 (UTC)

== How can I express search results as an external link? ==

Hi all

I'm trying to create something that uses links to search results with include and exclude the results of multiple categories, is it possible to express these links as internal links? E.g

== Fashion or style "based on" another ==

I have sources that state that the {{q|Q697666}} is "based on" the {{q|Q694050}}. (I have also run into this for other types of clothing.) Using {{P|P144}} for this relationship throws a constraint violation since clothing and its subclasses aren't currently works. I think the best way to resolve this is to make {{Q|Q11460}} a subclass of {{q|Q386724}}.

How can I show that an interior have been decorated by an artist?.

== Is there a limit to the number of references? ==

Is it possible to have too many references for a statement? I ask it because I was thinking about searching for all information available in a given publication or book - in particular textbooks - in order to use it in a [[:w:Spaced repetition#Software|Spaced Repetition Software]] like [[:w:Anki|Anki]]. If it would be possible to add as many references as possible, we could ideally represent in Wikidata all the information available in a textbook and export it in a flashcard software if someone need to study that textbook.--[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:37, 8 April 2018 (UTC)

:My perception is that the purpose of references is to help readers and other data consumers to verify that a statement is true, or at least, that the statement correctly reports the position of the referenced source. Creating large numbers of references for a single statement has at least two problems.
:#It is hard for the reader to wade through a long list of references and decide which ones are the best.
:#It is the responsibility of the editor adding a reference to actually read the reference and be sure that it actually supports the statement in Wikidata. This is a lot of work. Any editor adding massive numbers of references to a single statement in rapid succession will be suspected of failing to meet this responsibility.

== How/where to search through Category:Pages using Wikidata property P# ==

I found {{Q|28039488}}, now I want to look at all the pages that use P566. WD says it's a Wikimedia category, but it doesn't exist on Wikimedia nor on Wikipedia. — [[User:Tom.Reding|Tom.Reding]] ([[User talk:Tom.Reding|talk]]) 14:46, 9 April 2018 (UTC)

== Move request - Wikidata Query Service ==

I am requesting a page move at [[Wikidata_talk:SPARQL_query_service#SPARQL_query_service_versus_Wikidata_Query]].

I requested a move at the admin board at [[Wikidata:Administrators%27_noticeboard#Move_request_-_Wikidata_Query_Service]]. I got the suggestion to seek further community comment. The process for organizing a pagemove here is uncertain to me, but I think posting here to seek comments works. I would appreciate any comments on that user page about the move.

== Labels and desrciptions ==

Hello. {{Q|7916291}} and {{Q|7916293}}. 2 different villages with the same name. People added a second word after their name and we use to use that words even today. But their official name is the same. I was trying to add the official name in English (and Greek) with the same description but the system don't let me. I understand that in same cases when two items have the same label and same description maybe the same item. But in that case they are not. I had to change the description of one of the item. [[User:Xaris333|Xaris333]] ([[User talk:Xaris333|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:04, 9 April 2018 (UTC)

:It is the case that "no two items may have both the same label and the same description" per [[Help:Label]] so amending the description is indeed the way to go. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:25, 9 April 2018 (UTC)

::It seems useless to me. I just add Cyprus to one and Republic of Cyprus to the other. Same thing. I mean that the description its self may not be the way to show the different between them.

:::{{ping|Xaris333}} We routinely use common names instead of official names in labels; "India" instead of "Republic of India", "Hamlet" instead of "The Tragedy of Hamlet, Prince of Denmark", and so on. It makes sense to me to put "Vasa Kellakiou" and "Vasa Koilaniou" as the English labels, each with an alias "Vasa", and within each item leave the {{P|1448}} as you have left it.

::It is not useless. It serves to prevent duplicate items being created. The description is expressely "a short phrase designed to disambiguate items with the same or similar labels" (see [[Help:Description]]) and thus it is incumbent on us to concoct descriptions that effect that disambiguation - as Ghouston's example does. It's deliberately not okay to to seek a same label same description, and force the user to rely on other claims to disambuguate, since only the label and description are supplied in search results and so discovery of items by search is frustrated. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 01:22, 10 April 2018 (UTC)

== human (Q5) violates subclass constraint ==

On {{Q|Q5}}, the "subclass of: person" statement has an issue attached that I found rather confusing. It says "''conflicts-with constraint: An entity should not have a statement for subclass of if it also has a statement for instance of ([[Property:P31|P31]]) with value  common name ([[Q502895]]).''" --[[User:Krinkle|Krinkle]] ([[User talk:Krinkle|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 02:26, 10 April 2018 (UTC)

:I read this as saying, inter alia, that because "human" is a common name, it is the thing that it is a common name of (i.e. homo sapiens) that should have the subclass of person claim, and not the common name item. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 04:38, 10 April 2018 (UTC)

== anonymous (Q4233718) violates gender constraint ==

At {{Q|Q4233718}}, the "sex or gender: unknown value" statements shows the following issue: "conflicts-with constraint: An entity should not have statements for both {{P|P21}} and {{P|P279}}}}." Can someone explain why that constraint exists? And how should we solve it? --[[User:Krinkle|Krinkle]] ([[User talk:Krinkle|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 02:25, 10 April 2018 (UTC)

:Because sex or gender applies to an individual thing, which will be an instance of something, not a subclass of something. How to fix? {{Q|Q4233718}} is quite sucky right now. The en description somewhat nails it: the item is a {{Q|1969448}} which represents an unsupplied creator name. The item is not a human, nor is it a subclass of a humen, creator, etc etc. It is a term. The item should not, therefore, have lots of 'unknown values' for a series of attributes of humans. It should instead have claims that are suited to the description of the term, such as {{claim|Q4233718|P279|Q61002}}. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 04:04, 10 April 2018 (UTC)
:: If that was changed it would probably introduce other constraint violations when it's used for an author etc., like "author should have a gender". [[User:Ghouston|Ghouston]] ([[User talk:Ghouston|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 05:15, 10 April 2018 (UTC)

:In the first case, you seem to have conflated "Names of the days of the week" with "Day of the week". That's an error, since those are different concepts, and was rightly reverted.

:::# The English Wiki "Names of the days of the week" is actually the same article moved from "Days of the week". What topic of contents is different before the en-wiki article moved from "[https://en.wikipedia.org/w/index.php?title=Names_of_the_days_of_the_week&oldid=263652435 Days of the Week]" and after moved to the current "[[w:Names of the days of the week]]"? They are still all about the exact same topic: how to count the seven days, their astronomy origins and their names in different languages. "No one single language Wiki separates this exact same topic into two articles" is the strongest evidence that none of the 53 languages thinks that they are about different topics.
:::# I don't think good idea to separate the exact same topic of different languages simply because one has less content. This will break the cross-reference and cross-improvement connections among different languages.
:::# Of course, fiction includes novels and films.

== Linking templates to categories and lists without a main topic item ==

I'm wondering how to link an item for a list-like navigational template to the corresponding list and category items, when there is no corresponding main topic item. A specific example is {{q|Q20691005}}, which corresponds to the list {{q|Q1188621}} and category {{q|Q17392112}}. The category and list can be linked to each other without using a main topic, using {{p|P1754}} and {{p|P1753}}. Are there similar properties for templates, and should there be?

Then it began to be published in Brazil (1993), Portugal (1995), Angola (2004) and Uruguay (2007). In 1993, Grupo Perfil was associated with Grupo Abril and in 1995 it was associated with Grupo Impresa. In 2014, Grupo Perfil bought the part from Grupo Abril and today is the only owner of the franchise (Argentina, Brasil, Angola and Uruguay) except for ''Caras Portugal'' who continues to share with Grupo Impresa.

Some improvements have been made by the Search team at WMF on [[Special:Search]] (the page that is loaded when you type something in the search field and press enter, for example).
* The string that you typed is highlighted in bold in the label of the results
* The number of bytes is no longer displayed, instead you can see the number of sitelinks and statements
* The code is now using the same indexing as completion search, which should improve relevancy and better control over ranking

== Feedback requested on educational resources and curricula ==

I have a goal of creating a series of lessons which a new user could follow to gain the skills to use Wikidata.

I drafted an outline of resources.
*[[Wikidata:Wikidata educational resources]]
*[[Wikidata:Wikidata curricula]]

My thought is that I will seek to collect any lessons on the "educational resources" page, then include those individual lessons and more into a curriculum on the "curricula" page.

Here is the feedback I am seeking now:
#Can anyone inform me if they are aware of any Wikidata page which already serves either of these functions? Is there a catch-all directory of educational resources, and has anyone already outlined how to create a Wikidata class learning plan?
#Can anyone post more educational resources to that page?
#Can anyone direct me to individuals who are likely to want to collaborate in developing a multi-part lesson plan for new users to learn Wikidata?

:::There are probably three or four  main tasks associated with this proposed upload: 1.

Actually uploading the data, probably using {{Q|29032512}} and possibly 4. creating a new property for CODICESCUOLA (and, who knows, thinking about CODICEISTITUTORIFERIMENTO and whether we need to support that ID). So it's a non-trivial task, I'm afraid, one which will take a considerable amount of effort to achieve. There is not an automagical solution.

::::Thanks for your kind reply. So, I'd like to contribute and to try loading datasets for becoming confident with this process. I go over your points. 1. There are definitely record of such schools, for example this one {{Q|3268994}}. I guess the only way to get them all is string matching, right? How do I merge existing data? 2. Again, also in this case string matching is the only way, isn't it? 3. Aren't there APIs for loading data (e.g., the ones the bots harness)? Do I need a bot to load them? 4.

== Property "Time of the day" by using 1440 items ==

Since the use case of "time of the day" is different than the use case of "duration in HH:MM:SS", I was wondering if we could create a property "time of the day" with data type item which takes as value one of 1440 items (24h * 60min), each one labeled as "00:00", "00:01", "00:02", and so on. Would it make sense? Are there any use cases?

For opening hours I suppose we would need a property "open on" with item values "Monday", "Tuesday", etc. and qualifiers "start time of the day" and "end time of the day".

Thoughts? --[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:14, 13 April 2018 (UTC)

:I'm also thinking that perhaps there is no need to create so many items, as normally the only items used would be for hours, or half-hours, perhaps quarters in some rare occasions. In that case only 96 items (4*24) would be necessary to have the most used times 0h, 0:15, 0:30, 0:45, and so on. --[[User:Micru|Micru]] ([[User talk:Micru|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:36, 15 April 2018 (UTC)

== Records and record progressions ==

On the one hand, the English-language Wikipedia has an article called ''Flight airspeed record'', on the other hand, it has an article called ''Men's pole vault world record '''progression'''''.

Now two examples are given for {{P|1000}}, {{Q|1742}} → {{Q|1136293}} and {{Q|4821509}} → {{Q|1038621}}, but one cannot say that Lavillenie holds the men's pole vault world record ''progression''. What to do about this, changing the Wikidata label into ''men's pole vault world record'' but leaving the Wikipedia article linked to it? Note that the French label is ''record du monde du saut à la perche'' (OK) and the German label is ''Stabhochsprungweltrekord'''e''' der Männer'' (plural!).

I am also uncontent with the use of the property {{P|1000}} in the item {{Q|164761}}. It is not like Usain Bolt is a record held by the 100 metres race; rather, the record for the fastest 100 metres race is held by Usain Bolt. -- [[User:IvanP|IvanP]] ([[User talk:IvanP|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 15:12, 14 April 2018 (UTC)

: {{Q|1136293}} actually seems like the better target, because it's an item for a subclass of world records, unlike {{Q|1038621}} which is an item for a Wikimedia list article. I think it would be OK to change the label. {{P|1000}} in {{Q|164761}} is just backwards.

== Translating "Motivation" ==

Currently, property proposals have the string "Discussion" translated, by inputting <code><nowiki>{{int:Talk}}</nowiki></code> which outputs "{{int:Talk}}". It would be useful to have the header "Motivation" also internationalized. The preloaded property proposal template would also need to be updated.

== instance of:list and P279 ==

Somehow {{P|279}} doesn't work well on items for lists. That is items with {{p|31}}={{Q|13406463}}. 

There are some on [[Wikidata:WikiProject Lists/reports/P279 cleanup]]. It includes:
*1. Items with labels = "list of" and a subclass that is also labeled "list of"
*2. Items with labels = "list of" and a subclass that is not labeled "list of"
*3. Items with labels in plural (other than "list of") and a subclass that is not labeled "list of"
*4. Items with labels in singular (other than "list of") and a subclass that is not labeled "list of"

What to do?
*For (4), the solution would probably be to remove p31={{Q|13406463}}. 
*Maybe for (3) as well. 
*For 1 and 2, the value of P279 should probably be moved to another property. <br/>--- [[User talk:Jura1|Jura]] 16:34, 15 April 2018 (UTC)

== Refound date ==

We are using {{P|571}} and {{P|576}} for a team foundation date and dissolved date. But, what we do if a team refounded after dissolved? Two different questions I have.

1) We put the refounded date at P571, as a second value? But, it has the constraint {{Q|19474404}}. How can we show that the team was refounded a specific date?

2) We made P576 value a deprecated rank? (sorry for my English) 

3) If the team dissolved again? P756 has the constraint {{Q|19474404}}.

My example, 

{{Q|2277220}} founded at 1924, then dissolved at 1932 (merged with other team, created a new team), then refounded at 1937 and then dissolved at 1994 (merged with other team). For other teams, they just dissolved (not by merging) and refounded some years later.

: I'd say first decide whether the refounding is genuinely the same team, and not a new team with the same name. The same thing also happens with other types of organization like political parties and companies. If it a continuation, then I suppose you'd use {{P|571}} for the first founding date, and {{P|576}} for the final dissolved date, with periods of inactivity not recorded in that way.

:Identity is strongly associated to the temporal continuity of existence, which is delimited by a start date and an end date.

:: Wikidata doesn't really have the privilege of deciding such things: it's determined by whether the entity has multiple Wikipedia entries or a single entry. Perhaps a case will turn up that has multiple entries in one language and a singe entry in another. In reality its messy: there are likely to be aspects in which the entity acts as a continuation (beyond just the name, such as having some of the same people involved) and aspects in which it acts as a new entity (such as a new legal registration.) Did China become a new state in 1949 when it became the {{Q|148}}, or is was it a continuation of the same state with a new government and new name? We have {{Q|148}} founded in 1949.

== New constraint to enforce that two properties have the same value on a given item ==

There is an ongoing discussion at [[Wikidata:Property proposal/Directory of Open Access Journals ID]] and [[Wikidata:Property proposal/Plants of the World online]] (among others) about how to link to two different databases which use the same identifier. The simplest solution seems to consist in creating two distinct properties which would generally have the same value when they are present on the same item (but different URLs generated by the formatters). It can be a burden to deal with this redundancy so some editors wonder if a new type of constraint could be created to alleviate that. Would that be an appropriate solution? {{Ping|Lucas Werkmeister (WMDE)}} would it be technically feasible? − [[User:Pintoch|Pintoch]] ([[User talk:Pintoch|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 08:51, 8 April 2018 (UTC)

As I've noted elsewhere, "distinct properties which would generally have the same value" is far from simple, and is in fact a harmful way to proceed. Consider:

for which we currently have {{P|1727}} and {{P|1747}}; with a further ''eighteen'' potential properties to follow. Sadly, only four people responded when I raised this here and at [[Wikidata:Requests for deletions/Archive/2018/Properties/1#eFlora properties]].  <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> 10:52, 8 April 2018 (UTC)

:This seems to be a slightly different issue as all these URLs come from the same database. I understand that you vocally oppose the creation of these properties but I still don't understand what you are proposing to do instead (specifically for the two proposals linked above)? Third-party formatter URLs are not a solution for this particular problem. − [[User:Pintoch|Pintoch]] ([[User talk:Pintoch|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:14, 8 April 2018 (UTC)
::{{Tq|"Third-party formatter URLs are not a solution for this particular problem"}} Yes, they are; and that is the solution I have - quite clearly - proposed. <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> 13:34, 8 April 2018 (UTC)
:{{ping|Pintoch}} I tend to agree with [[User:Pigsonthewing|Andy]] here: we should be using a third-party formatter URL in these cases. Unless there is at least one instance where the identifier differs between, say, P1727 and P1747 for the ''same item'' (which judging from Andy's links is in the ''same database''), the two properties should be unified. What ''should'' be worked on is a way to control which formatter URL appears on a given item—in this case, based on some sort of geographical information on the item itself. [[User:Mahir256|Mahir256]] ([[User talk:Mahir256|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 18:46, 8 April 2018 (UTC)
::{{ping|Pigsonthewing|Mahir256}} Sorry if it is obvious but I still do not see how you would use a third-party formatter URL to indicate that a given identifier is available in database X but not in database Y? For instance, not all ISSNs can be found in DOAJ. Also I don't see in which context the third-party formatter URL is actually used to generate a link for the identifier in the Wikibase UI? It would be great if you could give a very concrete example of this, because I think that I am not the only one who does not get it. − [[User:Pintoch|Pintoch]] ([[User talk:Pintoch|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:13, 8 April 2018 (UTC)

::::To piggyback off [[User:Gerwoman|Gerwoman]]'s suggestion, why not have the formatter URL change based on a reference "{{P|248}} {{Q|5460442}}" or "{{P|248}} {{Q|1227538}}" as appropriate? [[User:Mahir256|Mahir256]] ([[User talk:Mahir256|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:22, 8 April 2018 (UTC)
:::::That's intuitively harder to implement, but why not. As far as I understand Andy claims that somehow no change is needed and third party formatters already provide a solution. − [[User:Pintoch|Pintoch]] ([[User talk:Pintoch|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:36, 8 April 2018 (UTC)
:::While it is ''not necessary'' to "indicate that a given identifier is available in database X but not in database Y" (that's what the 404 response code is for), it ''is possible'' to do so, using referencing, [[Wikidata:Project chat/Archive/2018/03#Plants of the World Online database|as I have demonstrated previously]]. {{diff|Wikidata:Project chat|638025636|638019339|You were apparently aware}} of the example I gave then. <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> 11:36, 9 April 2018 (UTC)

== IAFD person Ambiguity properties ==

There is an ambiguity with the IAFD person properties on Wikidata, IAFD male performer ID ([[d:Property:P4505|P4505]]) and IAFD female performer ID ([[d:Property:P3869|P3869]]), the correct one would be to only exist an "IAFD person ID" as like Adult Film Database person ID ([[d:Property:P3351|P3351]]) .
I believe that this ambiguity occurred because of the second parameter ''gender''. It was mistaken for a secondary ID, in fact it is just a layout parameter for the IAFD site.

All links below point to the same element on the IAFD site.

: <code>[http://www.iafd.com/person.rme/perfid=glynn http://www.iafd.com/person.rme/perfid={{hilite|glynn}}]</code>
: <code>[http://www.iafd.com/person.rme/perfid=glynn/gender=f/ginger-lynn.htm http://www.iafd.com/person.rme/perfid={{hilite|glynn}}/gender={{hilite|f}}/ginger-lynn.htm]</code>

This ambiguity makes it difficult to integrate with templates on Wikipedia.

::{{Ping|Rodrigo Tetsuo Argenton|Mike Peel}} before you start doing double work:
::The monuments database indexes about 1,5 million monuments ([[:commons:Commons:Monuments database/Statistics|stats]]). A lot of these id's are cross referenced with Wikidata already or that can easily be done. The monuments database used to index images too, last time it ran it was about 2,6 million images ([[:Commons:Commons:Monuments database/Indexed image|more info]]). I haven't invested any time yet on removing the intermediate step. To explain that, now it's file -> id, id -> Wikidata, that could be file -> Wikidata. The reason I haven't done anything yet is [[:Commons:Commons:Structured data|Structured Data on Wikimedia Commons]]. This is a good set to convert once we have the initial release of that deployed. It's a bit of double work to add Wikidata id's now in template pseudo structured data and doing everything again a bit later. 
::I would wait a bit and in the meantime focus on improving items with {{P|P1435}} and making sure all the items about monuments have at least [https://www.wikidata.org/w/index.php?title=Special:WhatLinksHere/Q18618628&namespace=120&limit=250 one of these properties].

== P31=Norse human ==

When working on [[property:P2600]] I found that one item is instanceOf Norse human [[Q24451723]]. There are many more humans linked via P31 [[Special:WhatLinksHere/Q24451723]]. Is this desired? [[Special:Contributions/78.55.76.113|78.55.76.113]] 18:43, 17 April 2018 (UTC)

== Books and Authors ==

I want some opinions. I created yesterday for [https://litteraturbanken.se/om/english.html litteraturbanken.se] a proposal [https://www.wikidata.org/wiki/Wikidata:Property_proposal/Person#Swedish_Literature_Bank_ID link]...

As it looks technical possible to have one property for both books and authors I start feeling its better to split this property into 
*  Swedish_Literature_AuthorID
*  Swedish_Literature_BookID
Any comments/suggestions?

My argument is that its conceptual easier implementing two properties- [[User:Salgo60|Salgo60]] ([[User talk:Salgo60|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 05:29, 18 April 2018 (UTC)

== "Better source needed" ? ==

Is there a way to indicate "better source needed" on a statement ?

For example, suppose I have a date and place of birth for somebody, from a genealogical website -- but it doesn't give primary sources.  The family relationships are right, confirmed by multiple primary sources; the year of birth ''might'' be right - it matches the age given on the death certificate; though the date on the tombstone is a year earlier; and ages given on other official documents, such as census returns, immigration forms etc are all over the place; there's also a place of birth confidently stated on the genealogical website, that seems quite a long way from the family's long-term residence, but doesn't seem to have come from any other source I can see online.

The subject died in 1908, so there's no BLP issue.

I'd like to include the stated birth-place, but note that its ultimate sourcing is not clear.  Is there an appropriate way to do this?  On some wikis one can tag a statement with {{Q|6716717}}.  Is there anything analogous here that one can do to mark a statement that could use better verification?  [[User:Jheald|Jheald]] ([[User talk:Jheald|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:41, 19 April 2018 (UTC)

:Found a line in an old newspaper.  Turns out that the tombstone was right, the place was right, the death certificate was one year and one day out.

{{SPARQL|query=SELECT (COUNT(?item) AS ?count)

Only two Wikipedias have more than 4 million articles, namely enwiki 5.6 mio, and cebwiki 5.3 mio [https://meta.wikimedia.org/w/index.php?title=List_of_Wikipedias/Table&oldid=17954214]. In the list [[:de:Liste genealogischer Datenbanken]] Wikidata would be ranked 26 by number of human items.

Are there a sparql queries that could show 
*how often VIAF ({{P|214}}) and ISNI ({{P|213}}) are used on instances of Q5
or even better
*lists quantities for each externalID that is used on any instance of Q5

According to [[Wikidata:Database reports/List of properties/Top100]] total VIAF ID (P214) = 1181059, GND ID (P227) = 606095, ISNI (P213) = 541276, BnF ID (P268) = 401272, but these numbers are not restricted to instances of Q5.

== CirrusSearch issue returning pages in multiple categories ==

Hi

So I'm having some issues with CirrusSearch which I'm 80% sure I'm searching for the right thing and following the instructions correctly but am not getting the results I expect. 

I'm working on a new version of [[Wikidata:Dataset Imports]] which has each dataset recorded on an individual page and using categories to organise the pages. I'm nearly done with this new version and once I've solved this issue people can use the page.

What I'm trying to do is run a search to find items that exist in '''both''' of two categories using the instructions [https://www.mediawiki.org/wiki/Help:CirrusSearch#Intitle_and_incategory here].

I've created a test page [[Wikidata:Dataset_Imports/test]] which is in both [[:Category:Medical datasets]] and [[:Category:Updated datasets]] and I'm trying to create a query in the search bar to find the page. I think it should be:

'''incategory:"Text document datasets" incategory:"Medical datasets"'''

However this doesn't give me any results..... Can someone tell me what I'm doing wrong?

Thanks

== Hemp fiber in English and Korean Wikipedias ==

Not sure what to do with this; [[:ko:삼베|삼베]] on kowiki links to nothing on enwiki when there is an article for it, [[:en:sambe|sambe]] on enwiki. But the English article is about the specifically Korean cultural usage. So I'm not sure {{Q|13414920}} with links to other languages should be broken (e.g. [[:de:Hanffaser]]). Help! [[User:Bri|Bri]] ([[User talk:Bri|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:26, 19 April 2018 (UTC)
: English Wikipedia does not have an article on (generic) {{Q|Q13414920}}, so there is no link there to [[:ko:삼베|삼베]].  Hemp fiber is discussed in [[:en:Hemp|Hemp]] which is linked to {{Q|Q7150699}} (''edited'': and in [[:en:Fiber crop|Fiber crop]]).  Many languages have both articles (and it looks at a quick glance like some of them are not linked to the best WD item ... Catalan [[:ca:Fibra de cànem|Fibra de cànem]] pretty clearly is about the fiber, not the industrial uses of the plant). As you point out, Enwiki [[:en:sambe|sambe]] is specifically about cultural Korean usage, and I think its WD item {{Q|Q48724197}} should probably be a subclass of {{Q|Q13414920}}.  If the RFC to allow links to redirects is approved, the ENwiki redirect [[:en:Hemp fiber|Hemp fiber]] would be pointed to {{Q|Q13414920}} which would solve this problem.

: If KOwiki allows manual interwiki links, you could link KO [[:ko:삼베|삼베]] to EN [[:en:Hemp|Hemp]] or [[:en:sambe|sambe]] as you please.

::::The American Ornithological Union checklists "are the official source on the taxonomy and nomenclature of birds found in this region, including adjacent islands." see here:  http://www.americanornithology.org/content/checklist-north-and-middle-american-birds . Looking at the current checklist here:  http://checklist.aou.org/taxa/ we have  Synthliboramphus scrippsi (Scripps's Murrelet) and Synthliboramphus hypoleucus (Guadalupe Murrelet). Therefore I believe, officially Xantus's Murrelet has been split, I don't think what other authorities say is relevant.  A species with name Synthliboramphus hypoleucus (Xantus's Murrelet) was deleted from the AOU list as per the 53rd supplement in 2012 http://americanornithologypubs.org/doi/pdf/10.1525/auk.2012.129.3.573 I'm not really a wikidata expert, but I would suggest the best course of action is to retain {{Q|46338167}} but change the {{P|31}} from {{Q|16521}} to something which indicates that this is a formerly recognised taxon, but which has been deleted.  I had a quick look but couldn't find an item that would describe that, but this must have happened before.  Species are split all the time.

::::::ok from the point of view of a taxonomist. Reading the paper from 2011 linked above by {{ping|JerryL2017}} the two taxa in question were considered subspecies, however overlap and do not interbreed in sympatry. By the definition of a subspecies this is not possible, hence they should be species and have been recommended as such by the paper also. As such from this viewpoint you have two species and should have two items one for each. Any other refs, unless you find one that refutes this primary ref '''''with data''''' not '''''opinion''''', are irrelevant. I see no reason for any further argument. The nomenclatural act has been made, follow it. Where the common names go whatever, they are vernacular names and not relevant to the concept of the species. That is my view on this so I would suggest fixing the pages to reflect this and as for the IOC, ummm they are not a primary taxonomic reference so why would you be adamant about it.

Please correct me if I am wrong, do you have separate pages for the scientific name and the vernacular names?? I do not understand why you would do that, but no matter. The vernacular name needs to follow the scientific name according to the most recent primary sources. No I do not consider the collective political opinions of eBird or the IOC nd simalar checklists as primary sources. When the species was split I imagine this did require modification of the accepted common names. As such you would use the primary refs that state this coupled with the research paper that did the nomenclatural act to move the common names accordingly. By the way, a taxon is not a concept it is an hypothesis, the concept is the theory of how species are differentiated, ie the grounds for calling something a species. That is for example the Biological Species Concept. However a species is a hypothesis circumscribed under a concept of the primary authors choosing. So please what are we getting t here cause your paragraphh Andy makes no sense. You are reporting science, it needs to reflect science.

:::::::::: OK, I will try and summarise and make some recommendations.  Up until about 2012/2013 the ornithological world recognised 5 species in the genus {{Q|287293}} .  One of these species had the latin name Synthliboramphus hypoleucus, common name Xantus's Murrelet. This is {{Q|46338167}}.  In 2012, in the paper cited above, it was proposed that the 2 recognised sub-species of {{Q|46338167}} ({{Q|47012925}} and {{Q|Q47012916}} be considered separate species and that {{Q|46338167}} be deprecated.  This hypothesis was accepted by the American Ornithological Union (they have a scientific committee which decides on such matters) and their taxonomy was updated so that the genus Synthliboramphus has 6 recognised species including: Synthliboramphus hypoleucus, common name Guadalupe Murrelet ({{Q|1276043}} AND Synthliboramphus scrippsi, common name Scripps's Murrelet ({{Q|3120531}}).  Subsequently a number of other sources have also adopted this new taxonomy (and I make no comment about how reliable these might or might not be) e.g {{P|2026}}, {{P|627}}, {{P|3444}} and others.  However a number of others, that are variously cited in wikidata's items have not adopted the new taxonomy.  How do I know they have not adopted the new taxonomy?  Because when you look at it in detail it does not include {{Q|3120531}}.  Examples of these include: {{P|685}}), {{P|815}} and {{P|850}} although there are probably others, I haven't yet reviewed all sources.  So, why have these sources not adopted the new taxonomy recommended by experts in the field?  I can see 3 reasons:  1) They don't agree with the hypothesis that Xantus's Murrelet is actually 2 separate species - I believe this is unlikely in this case) 2) They haven't updated their taxonomy (highly likely) and over time will probably update their data.  3) They have a scientific requirement to retain Xantus's Murrelet in their taxonomy because of pre-existing data that was linked to Xantus's Murrelet and not either of the sub-species.  A good example of this is {{P|3444}} where their taxonomy has Guadalupe AND  Scripps AND (by their nomenclature) an entity called Scripps/Guadalupe Murrelet (Xantus's Murrelet).  So, my conclusion is that  wikidata should retain {{Q|46338167}}, some sources are still using the former taxonomy and some bona fide sources WILL ALWAYS have an entity that is best described as Xantus's Murrelet.  However, having said that there are some outstanding questions we should resolve  1) For {{Q|46338167}} what is the best {{P|31}}. is it taxon or some other concept that better captures its status.  2) The existing wikidiata items should be updated to ensure each item is linked to sources that best reflect that item i.e. {{Q|1276043}} should NOT link to sources that have a taxonomy that does not inlcude Scripp's Murrelet.  3) Other data such as images and synomyms should be updated to make it less confusing. (NOTE: if we have agreement on this I am happy to go and make these changes IF I have assurance that they won't just all be reverted).   4) Consideration should be given within the wikidata taxonomy project for additional avian taxonomy properties (some key sources are not available as properties, which isn't helping here) 5) I've seen various comments on here that some sources are "unreliable" if there is a consensus that they are unreliable then why do we retain them?  6) IF we can resolve this case, consideration should be given as to how this is more widely applied within wikidata - for instance it is very common practise across many data recording schemes to "combine" species into groups when they are difficult to identify. I personally think wikidata should be able to reflect that, we are a broad data resource not a wildlife taxonomy.   Thanks, I hope this is useful and moves the discussion on a little.

::::::::::::Sorry [[User:Succu|Succu]], you are correct.
{{outdent}}ok what I have been trying to say is the taxonomic view of the situation, then it is for wikidata to determine how best to reflect the science. In answer to your questions from my point of view. This is a wonderful example of why common names are a pain, unprofessional and honestly useless. I agree with you {{ping|JerryL2017}} that the issues of different nomenclatures between sources is most likely lack of updating.  <br/>
1. There are three common names available for 2 species the names Xantus's Murrelet and Guadalupe Murrelet both apply to the scientific name ''Synthliboramphus hypoleucus'' however the former is now considered depreciated, and Scripp's Murrelet which applies to ''Synthliboramphus scrippsi''. When the species was split the current common name goes with the species that retained the original combination. There is no justification in retaining the common name Xantus's Murrelet for ''Synthliboramphus scrippsi'', or honestly at all. The name Xantus's Murrelet does not technically apply to a taxon anymore, it is considered depreciated, it is at best an outdated name of historic value only.<br/>
2. Agreed, removal of sources that are outdated in their nomenclature will avoid confusion, or if they must be stated have it as "stated in and as" so the the page is generally set up with the current nomenclature but make note of any departures from it without supporting them.<br/>
3. Agreed, all information possible should be updated, including where necessary file names and metadata for images. I would not revert anything. Cannot speak for others. But I think if we hammer out an agreed position I believe people are professional enough to follow it.<br/>
4. Avian taxonomy should honestly be following the ICZN code, which they do not. Further they have made recent efforts to dictate to other fields of taxonomy that their viewpoint should be followed, to a massive backlash. However, this is not our problem, we present the science we do not revise it. If you feel the need for further avian properties please elucidate these.<br/>
5. Your guess is as good as mine. I think there is a generalised tendancy in projects like this to grab every online reference possible, unfortunately with little consideration of the quality of what is presented and no fact checking. Basically the equivalent of ''google says this, it must be true''. Again I think this is also unprofessional, I think sources that are questionable should be examined by wikidata taxonomy project for validity and if rejected they are removed.<br/>
6. The act of combining species into groups is I think beyond the realm of a database. This is done through analysis of the given issue. Wikidata should be presenting the data, with reliable and good sources. As best as possible the primary taxonomic literature, in the scope of this issue, the thing that can come out of this is a better discussion on what is a good resource, the acceptance that complex cases need to be analyzed using only primary references, and that in taxonomic issues the relevant codes are the primary determinant on availability and validity. That is, ''if a name is published in accordance with the Code it is to be accepted as valid or refuted'', a point the avian taxonomists breach the code on repeatedly.<br/>

::Yes, it was established early on that in the real world there are/have been two circumscriptions for ''Synthliboramphus hypoleucus''. That is not a problem. There appear to be several problems:
::* Is this wider/older circumscription notable enough to rate a separate item of its own?
::* Is this wider/older circumscription indeed what Andy Mabbett intends with [[Q46338167]], given that he has already denied this. If not, what does he intend?
::* Is it worthwhile discussing if Wikidata should have items for concepts denoted by a standardised common name set by some bird organization? These clearly exist, but are they notable enough?
::* Given that bird organizations use deviant 'scientific names' with rules of their own, should we have a property for that? Something like "Avian scientific name" or more general "deviant taxon name, used by special interest groups" (to include butterflies)? Clearly, it is not a good idea to put non-Code-compliant names in P225.

:::{{Tq|Is this wider/older circumscription notable enough to rate a separate item of its own?}} I do not think so.
:::{{Tq|Is this wider/older circumscription indeed what Andy Mabbett intends with [[Q46338167]], given that he has already denied this. If not, what does he intend?}} My impression was that this is what is being suggested here, I also acknowledge Andy has denied this, but I have no idea what the purpose of this is in that case.
:::{{Tq|Is it worthwhile discussing if Wikidata should have items for concepts denoted by a standardised common name set by some bird organization? These clearly exist, but are they notable enough?}} I do not think they are notable in any great degree, unless they are a highly notable list. I would encourage the avoidance of confusion as a priority.
:::{{Tq|Given that bird organizations use deviant 'scientific names' with rules of their own, should we have a property for that? Something like "Avian scientific name" or more general "deviant taxon name, used by special interest groups" (to include butterflies)? Clearly, it is not a good idea to put non-Code-compliant names in P225.}} I prefer something along the lines of your second option, since it can be applied outside Aves (Birds) this can apply to Amphibians also. But I definitely agree anything that is non code compliant should be avoided in almost any circumstance.

::::The Wikispecies account is about the species in question as part of this, we do not worry so much about common names there as its not really what we are about.

:I will update wikispecies with the appropriate refs to show the two currently accepted species, and with a common name for each, with the relevant references (if anyone has them please send them to me) I need the original descriptions of both species and the treatment that recognises them as currently valid species. If you wish then you can use this to model your database entries on this. That is up to you. My suggestion is to follow what has largely been discussed here, in the absence of any other explanation. So I suggest you have data entries for each of the two species with the currently accepted common names for each taxa, with the original refs. I further suggest that you could delete the entry for the now depreciated common name and list it only as an alternative, older, no longer used name for the species ''Synthliboramphus hypoleucus'' in older treatments. Cite the paper that split them as species for justifying this. I would suggest calling the two data entries by the scientific name with the common names as description. This way the taxa are clearly defined and it can be noted the common names are less clear. Just my suggestions, your call.

== Standardizing historic patents, post #2 ==

We could start to standardize on an ontology for pre-1920 patents, as I mentioned in a [[Wikidata:Project_chat/Archive/2018/04#Standardizing_historic_patents|Project Chat post]] a week ago. Interest was limited.  And yet I would like to create a Wikidata WikiProject for this topic, analogous to the ones for [[Wikidata:WikiProject Companies|companies]], [[Wikidata:WikiProject_Organizations|organizations]], [[Wikidata:WikiProject_Universities|universities]], and [[Wikidata:WikiProject_Occupations_and_professions|occupations]].  Any objections?  Or advice?

I'd like to get started now.  In two weeks I have a meeting with specialists at [[Q177773|WIPO]], the UN organization that manages modern-day patent rights, and would like to get their support or a wise critique of the effort.  Some of their data could be uploaded eventually, and on the wiki side we might be able to set up automatic links analogous to the authority control templates so as to get immediately from a Wikipedia article about an individual to their patent documents across countries, a service not offered very well elsewhere for historic patents.  Modern patents are conceptually the same, but they refer to intellectual property rights that may still be relevant, or maybe they might be copyrighted, and they are longer and more difficult to read, AND there are more services designed to manage that sort of information which might be technologically relevant now. Therefore I think it is reasonable to start with the older ones. -- [[User:Econterms|econterms]] <small>([[User_talk:Econterms|talk]])</small> 22:53, 16 April 2018 (UTC)
: Go ahead and start the wikiproject, at least some of those in the other ones you link are probably interested. Is there any particular reason historic patents would be different from modern patents in terms of data structure/ontology? [[User:ArthurPSmith|ArthurPSmith]] ([[User talk:ArthurPSmith|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:32, 17 April 2018 (UTC)
:: Thanks kindly, [[User:ArthurPSmith|ArthurPSmith]]!  I will start it.  Historic patents can be a little different. (1) They may have been issued by governments that do not now exist, and therefore do not have standard two-letter codes.  E.g. Austro-Hungarian Empire, and the German and Italian states that existed before those nations unified to their current form.  (2)  Before legal standardization there might be more variation in the data in them although I have not noticed much of this. But the earliest ones did not always refer to technologies or inventions but to monopolies granted, e.g. by the British crown, or monopolies on the rights to import some particular kind of thing. (3) they had different term lengths from the modern standard.  This is not a long list but if we dig there would be more. -- [[User:Econterms|econterms]] <small>([[User_talk:Econterms|talk]])</small> 13:22, 20 April 2018 (UTC)
:: Also, for old patents, we can be sure they are not copyrighted any more and that they have no intellectual property traction any more ; that is, they do not represent legally relevant claims any more so we could treat them a little more informally.  -- [[User:Econterms|econterms]] <small>([[User_talk:Econterms|talk]])</small> 17:48, 20 April 2018 (UTC)
== REST API format for wikidata ==

I'm playing with the [https://www.wikidata.org/api/rest_v1/ REST API] for wikidata. The returned results for an item in html form (like http://www.wikidata.org/api/rest_v1/page/html/Q42) just seem to be a dump of the JSON data associated with the item. I presume if people wanted this, they would go to e.g. https://www.wikidata.org/wiki/Special:EntityData/Q42.json. I wonder if, like the wikipedia REST pages (e.g. https://en.wikipedia.org/api/rest_v1/page/html/Albert_Einstein), the data could be arranged in a neater, HTML-like way, perhaps even something like the tabular format seen on a normal "editing" page (i.e. https://www.wikidata.org/wiki/Q42), or perhaps with section headers and breaks inserted.

== Paper size tolerances ==

Can the value of {{P|2048}} and {{P|2049}} in items such as {{Q|12062327}}, {{Q|12062328}} etc. also include the permissible tolerance as specified in ISO 216 (±1.5 mm for dimensions ≤ 150 mm, ±2 mm for dimensions > 150 mm and ≤ 600 mm, ±3 mm for dimensions > 600 mm)?

I would state, for instance, that A1 has height (841 ± 3) mm and width (594 ± 2) mm, but is {{Q|12062328}} specifically about the ISO size? DIN 476 used to specify slightly tighter tolerances (±1 mm, ±1.5 mm, ±2 mm) – though the part DIN 476-1 about the A and B series has been withdrawn in favor of DIN EN ISO 216, so perhaps this is obsolete – and there may be other standards with different tolerances, so should I use a qualifier (which one?) or would that be in a separate item? We already distinguish between {{Q|43305767}} and {{Q|43351400}}, but these already differ by the “ideal” sizes. -- [[User:IvanP|IvanP]] ([[User talk:IvanP|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:14, 13 April 2018 (UTC)
:{{ping|IvanP}} yes to the first question, as easily as changing the value from '''1,189''' to '''1,189±3''' such as in [https://www.wikidata.org/w/index.php?title=Q12062327&type=revision&diff=665176582&oldid=665176509 this (now reverted) edit]. See also [[Help:Data_type#Quantity]]. I don't have a good answer for ISO vs DIN tolerance diffs; could be done as 2 items, could be done as 1 item with 2 measurements, each referencing the pertinent standard (and there may be an appropriate additional qualifier for the measurement & other claims, pointing to the standard, such as {{P|642}}?). --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 23:20, 13 April 2018 (UTC)

::Regarding the qualifier, I would not use {{P|3680}} since the standard ''defines'' the tolerances rather than just supporting the statement that they were set this way. I am unsure about {{P|1013}}; I would use it to make clear which measure is meant exactly (e.g., {{P|2048}} (''which'' height?) → {{Q|26970842}}), but in this case, the purpose is to make clear what kind of paper size is meant (namely, A0/A1/… as defined in ISO 216). Is {{P|642}} the way to go? Would love opinions. -- [[User:IvanP|IvanP]] ([[User talk:IvanP|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 09:03, 14 April 2018 (UTC)
::I suggest creating two items both with label "A1", and a description noting which item is for the ISO variant, and which item is for the DIN variant of the paper size specification. Then use {{P|248}} in references on each item, pointing to the specific ISO or DIN standard. Values of properties such as {{P|2048}} and {{P|2049}} would therefore be different on each of the two items due to the variance in tolerances allowed. I would also suggest a third item with label "A1" that is a disambiguation/class item, with the ISO and DIN items being instances of this item. Properties such as {{P|2048}} and {{P|2049}} would not be appropriate to use on this third item.

:::@[[User:Dhx1|Dhx1]] Ah, {{P|248}}! I am not happy with {{P|642}} either, because I would use it in relation to a property value, e.g., {{P|39}} {{Q|382617}} ({{P|642}} {{Q|323644}}), which would mean ''maire of Rochefourchat''. In our case, we have a ''name'' which may have multiple meanings. In the end of May, Wikidata should support [[Wikidata:Lexicographical data|Lexemes]] for lexicographical data, but this is not quite what we need here, since we want to describe the name language-independent. Should we make a disambiguation item for ''kilobyte'', ''megabyte'' etc. as well, then? {{P|2442}} currently has two values in {{Q|79741}}, 1,000,000,000,000 byte and 1,099,511,627,776 byte. The first one concerns the decimal terabyte, the second one the binary terabyte (tebibyte). We already have, e.g., {{Q|41650359}} for the number ''name'', where it says {{P|1269}} {{Q|3115521}} ({{P|3005}} {{Q|19202121}}) and {{P|1269}} {{Q|319582}} ({{P|3005}} {{Q|19202120}}). However, the long and short scale are not geographical objects (cf. value type constraint!). (@[[User:Bigbossfarin|Bigbossfarin]]) Besides, what to do about sitelinks? The German Wikipedia article ''[[w:de:Quintillion|Quintillion]]'' does mention the short-scale value, but its topic is really the long-scale value, conforming to the meaning of the name in German. The article says:
::::Die Bezeichnung ist nicht identisch mit ''quintillion'' im [[w:de:amerikanisches Englisch|US-amerikanischen Englisch]], das unserer [[w:de:Trillion|Trillion]] (10<sup>18</sup>) entspricht.
::::The denotation is not identical to ''quintillion'' in US-American English, which corresponds to our trillion (10<sup>18</sup>).
:::So should the article be linked in {{Q|41650359}} – as it is now – or rather {{Q|3115521}}? In contrast, the Kazakh article ''[[w:kk:Квинтиллион|Квинтиллион]]'' is linked in {{Q|3115521}}, but is actually about the short-scale value ({{Q|319582}}), while also mentioning the long-scale one (it says something like [I do not speak Kazakh]: “Quintillion – a one followed by 18 zeros, i.e., 10<sup>18</sup>. In some countries, a quintillion is 10<sup>30</sup>.”).

== What property is best to use for a "seat number" qualifier? ==

Is there any property that could be used as "seat number" to be used as a qualifier for the property {{P|463}} (and maybe {{P|39}})?
I want to put that as a qualifier for the statement that a {{Q|5}} is {{P|463}} of {{Q|207360}}. {{Q|207360}} has 18 distinct "seats" numbered from 1 to  18, and I want to be able to make a query listing all persons that have been the "holder" of a specific "seat", e.g. seat number 7.
The same could be used for various parliaments that have numbered individual seats.
I guess a possibility is to create 18 separate objects, one per specific "seat", but such a scheme may not be feasible for parliaments with maybe hundreds of individual seats. So I would prefer to use a qualifier.

None of the properties in the following list seems to be a perfect choice, so I would appreciate a recommendation on what to use as "seat number" qualifier.
{| class="wikitable mw-collapsible mw-collapsed"
|-
! Property !! Comment
|-
| {{P|1342}} || style="background:#ff9999;"| No, that is not for a specific seat.
|-
| {{P|1410}} || style="background:#ff9999;"| No, that is not for a specific seat.
|-

|-
| {{P|1545}} || style="background:#99ff99;"| '''This is the "least bad" that I have found''',<br />but it could be confused as a {{P|1545}} for the entire "academy/parliament" and not as the number for a specific "seat".
|-
| {{P|1618}} || style="background:#ffff99;"| Possibly, but a hockey player and a member of an academy/parliament seem rather different.
|-
| {{P|1824}} || style="background:#ff9999;"| No, that would be confusing.

| {{P|2802}} || style="background:#ffff99;"| Possibly, but maybe confusing.

== ICTV taxonomy latest version (Q45362532) ==

Hi all,

I'm using the virus [[Q580606|ICTV]] taxonomy of viruses to reference viruses on a website I'm working on and I was looking for a linked data format that would help me in keeping these taxonomic references up to date.
I was first glad to find on Wikidata a contribution about the ICTV taxonomy ([https://query.wikidata.org/embed.html#SELECT%20%3FICTV_Master_Species_List%20%3FICTV_Master_Species_ListLabel%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%3FICTV_Master_Species_List%20wdt%3AP31%20wd%3AQ45362532.%0A%7D%0ALIMIT%20100 List of ICTV master species list on wikidata]) since till now the ICTV website only provides an annual official release of the virus taxonomy in an Excel sheet format with about 1 thousand updates each year over the last releases (https://talk.ictvonline.org/files/master-species-lists/m/msl).

However, I'm interested in having fixed URIs that would have updated content when the taxonomy of these viral taxons are updated by the ICTV (basically updated labels and parent taxons, the previous label could be put in the "Also known as" section or in a more adapted statement ), but on Wikidata it seems that each release of the ICTV taxonomy exists with a kind of independance which is a kind of duplication of the information (cf: [https://query.wikidata.org/embed.html#SELECT%20%3FICTV_Master_Species_List%20%3FICTV_Master_Species_ListLabel%20WHERE%20%7B%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22%5BAUTO_LANGUAGE%5D%2Cen%22.%20%7D%0A%20%20%3FICTV_Master_Species_List%20wdt%3AP31%20wd%3AQ45362532.%0A%7D%0ALIMIT%20100 List of ICTV master species list on Wikidata]): Even if common terms in the different version of this taxonomy are well linked to the corresponding ICTV versions there is an incoherence when the terms are updated since a new URI with the new term is created. For example according to the ICTV history tracking system on taxonomy we can find that the current taxon officialy named [[Q29004365|Avian avulavirus 7]] was previously named [[Q18907779|Avian paramyxovirus 7]] but there is 2 distinct URIs for these terms on Wikidata (Q29004365 and Q18907779).
https://talk.ictvonline.org/taxonomy/p/taxonomy-history?taxnode_id=20161025


To me, and probably to most of the virologists, it is crutial to know what is the current ICTV taxonomy (ie:latest version) and keep track of the changes made so that we can know what is the current official name for a taxon (even if updated) and what is its current lineage (even if modified)... At the moment Wikidata is somehow providing a biased exhaustive view of all the existing releases of this ICTV taxonomy.   

I'm new to Wikidata and I'm new to Linked data too... so I was wondering if we could ask for a kind of merging contribution named "Latest version of the ICTV taxonomy" that would have fixed URIs for each taxon including the next updates of the ICTV taxonomy without changing the URIs? ... a new URI would only be created for new taxons (not for updates in the taxon names or lineage) and removed taxon in the taxonomy would consequently be marqued as moved to their parent taxon.

::::Thanks Succu. {{ping|D3fk dev}} I think we aspire to the arrangement you suggest - a single stable item for each virus. Right now the way in which ICTV release information is not conducive to us being able to achieve that. Although the website will provide a change history for each virus, the spreadsheets do not provide specific information on the nature of a change made to virus attributes from year to year. Even the URL for the change history of a virus will change from year to year. ICTV seem to lack, or seem not to promulgate, a primary key value for each taxon; and reserve the right to change all attributes of the virus, including its name. Together, that's a data nightmare. It would take some masterful web-scraping to glean the information we need from the ICTV website, which is a shame, because ICTV clearly have the data that we (and others - you - require). I think someone needs to make enquiries with info@ictvonline.org to see if we can get a release of data that ties together the names of viruses in each of the yearly releases, so that we can start to merge items and provide, as properties and qualifiers, their attributes as they vary over time. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 01:29, 14 April 2018 (UTC)

:::::Thanks Succu and Thanks Tagishsimon {{ping|succu}} {{ping|Tagishsimon}} Happy to see that you aspire to fix this problem that way. I've been in contact recently with ICTV poeple through the info@ictvonline.org contact point about having access to possible other formats of the ICTV database (ideally Linked Data)... They are really open to create specific releases of their species spreadsheets (actually they are already providing their data in the form of a slightly modified spreadsheet to a number of taxonomic databases including Species 2000 "Catalogue of Life" and the World Registry of Marine Species). They've said that they were planning to find an alternate way to provide their data to the scientific community and the public... I've already suggested Wikidata as the best solution for this and they said they find number of advantages in using Wikidata (I didn't know at that time that there was already a contribution for the ICTV species list on Wikidata). Could you contact them about the ideal format (e.g.: including an ID for each taxon and the previous known names and parent taxon in case of update) for the succubot so that  this consistency problem on Wikidata could be fixed in short terms? -- [[User:D3fk dev|D3fk dev]] ([[User talk:D3fk dev|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 9:51, 16 April 2018 (UTC)
::::::{{ping|succu}} {{ping|D3fk dev}} I pinged info@ and Prof. Elliot J. Lefkowitz was kind enough to respond ... in short, providing alternate means of access to taxa history data is in their to-do list, but the list is long and the work is done in their free-time. (And they have data gaps in places - e.g. no info in the database as to which of the 1979 taxa were merged, in 1999, into either Human enterovirus C or Poliovirus, in https://talk.ictvonline.org/taxonomy/p/taxonomy-history?taxnode_id=20171985 ) I have not, at this time, asked them to do anything to alleviate our issue; I think we would need to have someone, or a team, ready to work with them before asking them to consider the effort required to provide a special cut of data for us. I'm now thinking that we might be able to make progress with a modicum of web scraping, but need some time to ponder on that. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 20:51, 16 April 2018 (UTC)

:::::::{{ping|succu}} {{ping|Tagishsimon}} good news! However, don't you think that simply having access to a slightly modified version of their ICTV spreadsheet including 1 row per taxon and an additional column for the unique ICTV taxon ID + an additional column for the previous taxon name known + a latest column for the previous parent taxon known... should be sufficient for the succubot to make links within existing data on Wikidata and solve this issue? -- [[User:D3fk dev|D3fk dev]] ([[User talk:D3fk dev|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 7:43, 17 April 2018 (UTC)
::::::::There is certainly a tabular data representation to be had which conveys the information we need. Lefkowitz made the point that they had in the past sought to do exactly that, but ended up with a complex hard to understand spreadsheet which was difficult to maintain. I don't think your 2 -line spec covers all of the complexities of merge, split, rename, reparent; and it is because I don't have the headspace right now to think through the issues (because, IRL) that I chose not to persue a suggestion that the volunteers at ICTV redirect their effort to satisfy our needs. Equally, slow time, I'm still looking at their website with a view to scraping. But right now I have a sash-window to dismantle. Very exciting. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:56, 17 April 2018 (UTC)
::::::::: {{ping|Tagishsimon}} Actually ICTV updates complexity could be resumed by :
:::::::::* New taxon(= a new ICTV unique ID in the spreadsheet = a new URI to create: solved by the ICTV unique ID column)
:::::::::* Renamed taxon (= same ICTV unique ID = same URI on wikidata with changed label and the previous label moved in a "previous/former name" property of the taxon type or in the "also known as": situation solved by the previous taxon name column, the current taxon name and the ICTV unique ID)
:::::::::* Moved taxon= reparent (= Same ICTV unique ID, same taxon name but different previous parent taxon name from the current parent taxon name = same URI but changed parent taxon property of the property of the taxon type statement)
:::::::::* Moved and renamed taxon (=Same ICTV unique ID, different taxon name from the previous taxon name and different parent taxon name from the current parent taxon name)
:::::::::* Deleted taxon (ICTV unique ID not anymore in the taxons list = URI unlinked from ICTV source and marked as deprecated)

:::::::::"Spliting" might be resumed by the creation of new taxon or a new taxon+ a renamed taxon
:::::::::"Merging" seems equivalent to a deletion or a deletion + a renamed/moved taxon 

:::::::::I agree that keeping all historical data in a single file would be a mess but if they continue to work with yearly distinct ICTV release files it should be ok.
:::::::::The main interest of having a dedicated spreadsheets release for Wikidata would be the stability of the data format and the direct implication of ICTV in delivering their data to the scientific comunity and to the public through Wikidata; versus a web scraping only initiated by wikidata that could miss data if ICTV decides to change their web interface.

:::::::::: There is another difference: We accept different taxonomic viewpoints for plants, animals etc. and model them around {{P|225}}. But for virus taxonomy there is only ''one'' taxonomic viewpoint, that of ICTV. So your proposal change labels etc. is not working in the general context how WD handles taxonomic issues. But WD should be able to keep track that the species ''Bovine papilloma virus'' from the [https://talk.ictvonline.org/taxonomy/p/taxonomy-history?taxnode_id=19710051 ICTV 1st Report (MSL #01)] in 1971 evolved into {{Q|18972422}}, {{Q|18972592}} and {{Q|18972997}} today. A additional column for renamed taxa would help ofcourse. --[[User:Succu|Succu]] ([[User talk:Succu|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 15:34, 17 April 2018 (UTC)
::::::::::: {{ping|succu}}  Yes, you're right ICTV represents on the web only 'one' taxonomic viewpoint on the virus taxonomy information available through the web and ICTV with their yearly update system probably works somehow differently than others in the world of taxonomy ... but this ICTV point of view on virus taxonomy is recognized within the complete virologist community as the single '''Official''' taxonomic viewpoint on "virus taxonomy" and all the other taxonomic viewpoints existing on the web at the moment that are different from the ICTV point of view on the virus taxonomy are just late to catch up on the ICTV taxonomy(eg:  Species 2000 "Catalogue of Life", the World Registry of Marine Species, or even the [https://www.ncbi.nlm.nih.gov/Taxonomy/Browser/wwwtax.cgi?id=10239 NCBI taxonomy] that mentions "The NCBI taxonomy database is not an authoritative source for nomenclature or classification - please consult the relevant scientific literature for the most reliable information.").
::::::::::: So trying to retranscribe in Wikidata all existing virus taxonomies through the web at a moment is really confusing since it participates to maintain deprecated nomenclatures in the world of viruses nomenclature. It would be wonderfull if Linked data could make more sense in the world of taxonomy and not simply tending to be exhaustive.
::::::::::: Moreover, if URIs of the ICTV virus taxonomy could be fixed with updated labels on taxon updates by ICTV (as well as updated statements on parent branching and naming history), Wikidata could became a wonderfull tool for spreading an up to date virus taxonomy to the world.... '''Simply imagine how wonderful it would be to simply have to reference a WD taxon URI once and to get the latest known name and lineage for this taxon at each request'''! Wikidata would become for sure the main data provider for most of users of the virus taxonomy. To reach that goal the Wikidata bot used for virus taxonomy could be adapted to handle the virus taxonomy slightly differently from other kingdoms taxonomies... simply in order to make more sense within the data. You're right that WD should also be able to keep track of the evolution of the species/taxon names (history allows to catch up on the current taxonomy), but it could be done by recreating a new URI for the former species/taxon names at each ICTV taxon update. A subclass of {{Q|16521}} like "Former taxon" or "Historical taxon" could be imagined or even a subclass of {{P|225}} like "Former taxon name" could be useful. At the moment on WD we can find several instances of a taxon for a current taxon and all the historical versions of this taxon but in reality it is question of the same taxon that was renamed but WD doesn't link this information for now  -- [[User:D3fk dev|D3fk dev]] ([[User talk:D3fk dev|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 8:22, 19 April 2018 (UTC)

:::::::::::::{{ping|succu}}  I suggest that abolished taxons (deleted names) should simply be considered as moved to their parent taxon (This is how it is handled in the ICTV spreadsheets)... therefore, a WD '''merging''' process should do the stuff (+ creation of a "former taxon" instance with the abolished taxon name for the label in order to maintain history).
::::::::::::: I have no problem in having a "complete" list of the latest master species names entered in WD, tagged with ICTV latest version (a SPARQL request [https://query.wikidata.org/#prefix%20prov%3A%20%3Chttp%3A%2F%2Fwww.w3.org%2Fns%2Fprov%23%3E%0Aprefix%20pr%3A%20%3Chttp%3A%2F%2Fwww.wikidata.org%2Fprop%2Freference%2F%3E%0ASELECT%20%3Ftaxon%20%3FtaxonLabel%20%3FrankLabel%20%3FparentLabel%20%3Fparent%0AWHERE%0A%7B%0A%20%20%20%20%20%3Ftaxon%20p%3AP105%20%3Ftaxonrank.%0A%20%20%20%20%20%3Ftaxon%20p%3AP225%20%3Ftaxonname.%0A%20%20%20%20%20%3Ftaxon%20p%3AP171%20%3Fparenttaxon.%0A%20%20%20%20%20%3Fparenttaxon%20ps%3AP171%20%3Fparent.%0A%20%20%20%20%20%3Ftaxonrank%20ps%3AP105%20%3Frank.%0A%20%20%20%20%20%3Ftaxonname%20prov%3AwasDerivedFrom%20%3Fref.%0A%20%20%20%20%20%3Fref%20pr%3AP248%20wd%3AQ29000566.%0A%20%20%20%0A%20%20%20%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22en%22.%20%7D%0A%7D like this] listing parent taxons would have the power to provide you with the lineage).... the main problem here is that if I'm using a WD URI to reference a taxon name on my website, this URI will be obsolete on the next ICTV update of the taxon name: so all entities in the world(websites, databases, URIs ... ) referencing that URI for the taxon name will display obsolete information since they are using an URI that return a deprecated taxon name that is even not anymore a taxon name (but a former taxon name)... this is not the way linked data should work ... URIs for the latest taxon name should always return the latest taxon name not a deprecated taxon name: Linked data have that power to create consistency with data. 
::::::::::::: So, the second problem you mentioned should be solved by this update labels approach: If the wikidata articles or even the wikispecies host track are using an URI to reference a taxon name, they will be updated in the same time that the label and the statements of that URI: e.g. for now, referencing {{Q|22106453}} should return '''Rotterdam reptarenavirus''' since it was renamed to this taxon name in the latest ICTV release {{Q|51526638}}, but it is not returning this taxon name, '''it is not returning a currently existing taxon name''' and there is no way to have Q22106453 linked with the real data in WD at the moment. -- [[User:D3fk dev|D3fk dev]] ([[User talk:D3fk dev|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 16:00, 22 April 2018 (UTC)

== Quick community survey: notability of family members due to “structural need” ==

There are occasionally items about family members of notable persons (parents, children, siblings, and so on) listed at [[Wikidata:Requests for deletions]] (there are some cases listed these days). When they are linked from the item of the notable person, it is often argued that these family members are also notable due to “structural need”. However, I am not sure whether such relations really create “structural need”. One could easily extend this approach and consider the relatives of the family members also as notable, and very soon each and every human being would be “notable” for Wikidata. We simply don’t have the capacities to manage this appropriately; I have also serious concerns about privacy issues, particularly (but not only) if items about minors are created.

The ongoing [[Wikidata:Requests for comment/Privacy and Living People]] as well as [[Wikidata:Living persons (draft)]] and [[Wikidata:Living people]] do not cover this problem appropriately, to my opinion. What does the community think about the problem? In which situations does the “structural need” criterion justify to have family member items? In which cases not? What’s the use case to equip family members with individual items when their only (notability-relevant) achievement is to be the relevant of someone else? Which minimum sourcing requirements should we have for those cases? What else do you have to add to this survey? I am open for any kind of input here, thus feel free to express your opinion. Thanks, [[User:MisterSynergy|MisterSynergy]] ([[User talk:MisterSynergy|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 10:56, 20 April 2018 (UTC)
: The RFC and living persons policy proposal are not concerned with notability, that's a separate issue. I think if the family members would be indicated in any way on a language wikipedia article about the "notable" person, then we should have (limited) items for them in wikidata.

:The structural need for family members is particularly to establish and show relations.. So fathers, mothers link their children to grand parents.. Genealogy is one structural need.

:: The structural need is that if you want to name somebody's spouse or child you need to create an item for them. The questions are whether their spouse and child really need to be named, and if so, how many additional statements can be added to these spouse/child items. Potentially such additional statements could require the creation of further items for the same structural need, and so on until everybody is on Wikidata.

*There are a lot of historical dynasties in art, politics, local land ownership etc that it is useful to be able to retrieve precisely.  If we have an item for the grandparent and an item for the grandchild, then I think in most cases it would be useful to have an item for the parent in between.  In very many cases the relevant people will probably not be living; but even when they are living, the connection is very likely to be public and generally known, through standard reference sources such as (in the UK) ''Who's Who'', ''Burke's Peerage'', ''Debrett's Distinguished People of Today'', newspaper profiles, etc.  When we have such a source for the information, that is readily publicly accessible, then I think the item ''would'' be appropriate to create.  For more distant relationships {{P|1038}} with {{P|1039}} is available.

*I appreciate the concerns where the newly-created items are themselves living people, and a decision on that might be useful, but I would ''strongly'' urge that we don't make a blanket policy against creating these linking items for non-living people. This sort of thing is massively useful for building relationship links between historical figures, as Jura & Jheald say, and IME the {{P|1038}} approach for "skipping" people doesn't work well compared to a standard family relationship.<br>One approach might be to firm up "structural need" to say that ideally you need the item to be linked from *two* independently notable items, or at least be part of a chain that connects two items. So we would allow, for example, linking someone to their great-grandmother by creating the father and grandmother items, but discourage creating items for all the cousins etc who aren't part of the direct chain.

* For me, as long as you have at least one source, there is no problem to create *all* known familly numbers and it's often much easier and proper to create these items than to use overrefined and convoluted statements. The only exception is maybe living people, a different question that need a different approach.

* I don't think Wikidata need to restrain the rules for dead people. I'm more worried by the property nombre d'enfants {{P|1971}}. There is not a lot of datas on that subject on the Internet except genealogical websites. But but babies and child dead very young are rarely mentioned. When someone change the value of {{P|1971}}, I can't fact-check quickly if it's a vandalism or not.

== Will "applies to part" work well with conversion factors? ==

{{Q|577}} has recently been edited to add several {{P|2442}}, each with a property {{P|518}}, for different kinds of years, such as common year and leap year. Will the various bits of software that automatically interpret conversion factors be able to take into account the {{P|518}} or will the software become confused and only see several contradictory conversion factors? [[User:Jc3s5h|Jc3s5h]] ([[User talk:Jc3s5h|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]])

:On further consideration I have removed the conversion factors because the item contains {{P|1889}} for common year and leap year. [[User:Jc3s5h|Jc3s5h]] ([[User talk:Jc3s5h|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:56, 23 April 2018 (UTC)

===Are "different from" and "subclass of" incompatible?===
{{Q|577}} asserts it is {{P|1889}} {{Q|3186692}}. But "Calendar year" says it is {{P|279}} of {{Q|577}}. Are these statements incompatible? If we decide a year is not different from a calendar year, they we will have to increase the tolerance on the year-to-seconds conversion factor so the tolerance is about a month, since many calendars have "leap months" to keep them roughly in sync with the year. [[User:Jc3s5h|Jc3s5h]] ([[User talk:Jc3s5h|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 16:27, 23 April 2018 (UTC)
: I'm not sure that "different from" is very useful in this context, since subclasses are always different from their parent classes, otherwise they should be merged. Subclasses of {{Q|577}} seem to be done on the principle that {{Q|577}} is any time period roughly based on the period of the Earth's orbit around the Sun; if {{Q|577}} is given a precise definition, it doesn't work.

: When we've got {{Q|577}} {{P|2047}} 31,558,000±1,000 second, it really doesn't make sense that {{Q|3186692}} is a subclass, since {{Q|3186692}} can be a quite different period of time depending on the calendar.

: Likewise, {{Q|2649}} {{P|31}} {{Q|577}} doesn't make sense, because {{Q|2649}} is an instance of a calendar year, specifically a year in the {{Q|12138}}, and wasn't a period of 31,558,000±1,000 seconds. As a non-leap year, before leap seconds were invented, it was 31,536,000 seconds.

:: {{ping|Ghouston|Jc3s5h}} I think {{Q|2649}} and {{Q|25291}} should not be an instance of {{Q|577}}, but an instance of {{Q|3186692}}, because {{Q|25291}} is not an instance of an instance of {{Q|1790144}}, but an instance of {{Q|186081}} or {{Q|186408}}. Maybe we need to remove all "{{P|31}} {{Q|577}}" statements from each specific year items, and make them instances of {{Q|19828}} or {{Q|235729}}, which are subclasses of {{Q|3186692}}.

Currently, the Wikipathways ID is of type String. It is, however, an external identifier. [https://phabricator.wikimedia.org/T192598 It apparently can be changed accordingly] but requires community consensus. Can we reach consensus here? Who supports, who objects and why?

== {{P|P969}} vs. {{P|669}} for japanese address ==

I'm confused about the using of {{P|P969}} and {{P|669}}. I would like to add the street address of the headquarters location {{P|159}} for japanese companys. For instance: 東京都杉並区阿佐谷北1－46－4 友和ビル5階

On the Property Talk Page of P969 you can read:  "Use located on street (P669) and street number (P670) for multilinguage use" BUT on the Property Talk Page of P669 you can read: "In such cases [japanese addresses] you use located at street address (P969)"
Now I don't know which is the right way. Any recommendation?

:: {{ping|Diggr|Liuxinyu970226}} With a very few exceptions, street names are seldom used in postal addresses in Japan. That is because most of the Japanese streets do not have their name. (see [[w:en:Japanese addressing system]]) So we can't use the pair of {{P|669}} and {{P|670}} to express the address of locations in Japan. As you may know, the value type of {{P|P969}} is not item but string, so the values depend on {{Q|8229}}, {{Q|190502}}, etc. I can strongly feel the importance of new system or model to represent Japanese addresses that is independent of languages. --[[User:Okkn|Okkn]] ([[User talk:Okkn|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 15:46, 18 April 2018 (UTC)
::: {{ping|Liuxinyu970226|okkn}} Okay. If I understand you right, I should use {{P|P969}} for now, but it's not the elegant way. It would be better to have a new model. As an example, I edit the japanese company {{Q|Q650867}} and added {{P|P969}} and {{P|281}} (the use of postal code seems unproblematic to me). Are there any objections to that? I think it is really necessary that it is possible to represent addresses (with local characteristics) correctly in wikidata.

::::If you are asking my consideration on both property, I'm afraid that I personally don't like {{P|969}}, because that isn't a monolingual text property, and such contexts on zhwiki are mostly "separated" by languages, but the de facto way seems okay for me. --[[User:Liuxinyu970226|Liuxinyu970226]] ([[User talk:Liuxinyu970226|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 09:07, 25 April 2018 (UTC)

== Trailing space problem ==

{{tracked|T193214}}
Context of this question is values for {{P|2580}}. For whatever reason, BBL *require* a trailing space on some of their URL fragments, so:
* http://www.bbl-digital.de/eintrag/Beggrow-Hartmann-Olga-1862-1922%20/ - works
* http://www.bbl-digital.de/eintrag/Beggrow-Hartmann-Olga-1862-1922/ - does not work
How do we get a trailing space into the BBL value in {{Q|36538626}}? The user interface will not allow a plain trailing space. And using %20 in the P2380 value results in an output of %2520. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:13, 23 April 2018 (UTC)

== Mass corrections to format of property ==

The URLs of an external site changed their formatting and now all property values https://www.wikidata.org/wiki/Property:P3064 for Lepindex need to have the taxonid without a trailing ".0" - is there a way someone could automatically fix this change?

: Isn't it automatically the case that properties are inherited by instances or subclasses?

::{{Ping|Ghouston}} It's not automatic.

:::I was not involved when this was set up and I do not really know the reasons, thus I have to speculate.

The world it quite complex and diverse, and so is the representation of it that we build here …<br>However, with the [//query.wikidata.org/ Wikidata Query Service] it should be possible to investigate and compare all kinds of data sets, also particularly for wrong values/outliers/special cases and so on.

:::::{{Ping|MisterSynergy}} Value inheritance can be assigned to properties (everywhere that property is used, its value is inherited to all item children) or to specific items (the value of some given property of this single item is inherited to his children). Value inheritance for properties is definitely more prone to errors and exceptions, but for single items the exceptions should be a lot less and the fact that the value is visible in many items instead of only one should make easier to spot mistakes.

{{Ping|MisterSynergy}}IMO, the advantages are two:
* don't have to manually repeat the value for every instances/subclasses, especially if there are thousands of them. Probably it could be done with QuickStatements or using the API but it is way more complicate;
* it is easier to spot inconsistencies if an instance/subclass has a different value than the parent item while they should have the same value: it can be determined on a case by case basis if the children represent an exception or the parent item has a wrong value.

::* through a "has value" property similar to "has quality" but for values instead of properties;
::* through an "has quality" qualifier like "value" or "preferred value" (if children items can have different values);
::* through something like the ranking icon.

== Single value constraint and deprecated statement ==

The item {{Q|Q73073}} is flagged in the "single value" constraints violation of {{P|442}} because the value changed in year 2000. However, the item seems correctly represented to me, with "start time" and "end time" properties, as well as using "deprecated" rank for the previous value.

Is there a way to tell the constraint violation checks to ignore past values? I feel like deprecated ranks should be ignored for these checks, or maybe a better management of {{P|580}} and {{P|582}} is needed, which would allow to check for overlapping periods as well?

[[User:Koxinga|Koxinga]] ([[User talk:Koxinga|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 05:56, 23 April 2018 (UTC)

* If was a correct value in the past, it should not be using deprecated rank. Normal rank is just fine, and preferred rank for the currently valid value.
* While it is using deprecated rank at the moment, the covi gadget does not report a violation. KrBot's list does, but the software generating these two reports is completely different.
* There was a related discussion at [[Wikidata talk:WikiProject property constraints#Count best-rank statements in “single value” constraint]] recently. Very likely there will be a new “single best-rank value” constraint type soon that allows to have multiple values, but only one with best rank. The introduction of such a constraint is motivated exactly by the situation you are experiencing.

== Motorways and controlled-access roads ==

{{Q|Q19875}} and other British motorways seem to have {{P|P31}}={{Q|Q46622}}. "Motorway" seems to be an alias for that, and the description is "highway designed exclusively for high-speed vehicular traffic, with all traffic flow and ingress/egress regulated". Except that these motorways are not controlled-access, and don't have regulated ingress/egress. Maybe this is the result of a past-merge-gone-wrong, although I can't easily spot it. Any thoughts?

:{{Q|Q46622}} looks like a euphemism to avoid having to choose between motorway, freeway, expressway ... to stop the English speakers falling out amongst themselves. There are regulations on access to UK motorways, and so 'ingress/egress regulated' is more or less appropriate. The only fault I see with {{Q|Q19875}} is {{P|P31}}={{Q|34442}} since {{Q|Q46622}} is already a subclass of {{Q|34442}}. --[[User:Tagishsimon|Tagishsimon]] ([[User talk:Tagishsimon|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 00:58, 23 April 2018 (UTC)

== Is there a problem renaming a page that has translations, [[Wikidata:Data donation]]? ==

Hi all

I'm thinking about suggesting renaming [[Wikidata:Data donation]] to something like [[Wikidata:Publishing data on Wikidata]], the current title is not a correct description of the page and also suggests people publishing data on Wikidata are giving something up which is not very helpful. The page has 20+ translations, is renaming the page as simple as moving it, or will this break something? Also what do people think about the name change, its an important page to get correct as it is a well used page for partners interested in sharing their content on Wikidata.

Thanks

: So to be clear, external identifiers are most useful when they uniquely identify the item they are attached to.

The [[Wikidata:Notability]] guidelines are significantly looser than those of the English Wikipedia.  The requirement is that an entry {{Tq|refers to an instance of a clearly identifiable conceptual or material entity. The entity must be notable, in the sense that it can be described using serious and publicly available references.}}  For "small businesses", would an entry in a chamber of commerce directory (for example [http://web.saginawchamber.org/Day-Spa-Spa-Services/Ziba-Medical-Spa-6256]) which includes a business website and hours operation be sufficient to meet this threshold?

Hello, I was trying to add wikidata data in sawiki infoboxes, but all the output (numerical) is in english numbers. For example see 476 and 13 June 1992 on [https://sa.wikipedia.org/wiki/%E0%A4%B8%E0%A4%A6%E0%A4%B8%E0%A5%8D%E0%A4%AF%E0%A4%83:Capankajsmilyo/%E0%A4%AA%E0%A5%8D%E0%A4%B0%E0%A4%AF%E0%A5%8B%E0%A4%97%E0%A4%AA%E0%A5%83%E0%A4%B7%E0%A5%8D%E0%A4%A0%E0%A4%AE%E0%A5%8D sawiki].

== What duplicate rates should we tolerate? ==

{{ping project|Duplicates}}

Creation of duplicates is a general problem, especially for mass creating items from external databases. Discussing the most recent and very general case I hope we can find consensus on what to tolerate for future cases!

Since Tuesday, [[User:Reinheitsgebot|Reinheitsgebot]] has [https://tools.wmflabs.org/wikidata-todo/user_edits.php?pattern=wbeditentity-create.*mixnmatch_people_creator%24&user=Reinheitsgebot&doit=Do+it created  more than 3000 human items] with the mixnmatch_people_creator by [[User:Magnus Manske|Magnus Manske]] ([https://bitbucket.org/magnusmanske/mixnmatch/src/669930fd67ce037a098e07069c63d479757cb1f6/scripts/create_new_people.php?at=master&fileviewer=file-view-default source code]). I've reviewed the [https://www.wikidata.org/w/index.php?limit=20&title=Special%3AContributions&contribs=user&target=Reinheitsgebot&newOnly=1&end=2018-04-24 last 20 items of the first run] as a random sample. Of those 5 were duplicates. This is 25%.

I see duplicates as a serious problem and think this is much too high. I propose to complement the first paragraph of [[Wikidata:Bots#Approval process]] after “before the test run is started.” with
<blockquote>{{tq|“A bot task creating items must show not to exceed a duplicate rate of ''THRESHOLD''% demonstrated with a ''REASONABLE'' sample.”}}</blockquote>
and [[Wikidata:Blocking policy]] after “Unauthorised and/or malfunctioning bots” with
<blockquote>{{tq|1=“and users running automated tasks except for those that can be stopped separately ([https://tools.wmflabs.org/quickstatements/#mode=batches QuickStatements batches]). Malfunctioning includes creating items with a duplicate rate higher than ''THRESHOLD''% demonstrated with a ''REASONABLE'' sample.”}}</blockquote>
I'd personally favor a threshold of perhaps 2%. I expect many will think this is too low, but let's see! The qualities of the sample would have to be figured out.

::*Assume that the number of duplicates is given by d

I'd advocate for 5% to 10% as allowable - that cuts the number that might have to be handled manually by a factor of 10 or 20 from the original dataset, so hopefully manageable. A 25% duplicate rate leaves remaining manual work comparable to what you would have to do with no automation at all, so I'd argue the automation is not helpful in such a case. [[User:ArthurPSmith|ArthurPSmith]] ([[User talk:ArthurPSmith|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 21:58, 27 April 2018 (UTC)
* I'm not sure a fixed threshold is helpful here, as it depends on the scale of the import - an import that creates 10 new entries with 5 duplicates is quite different from one that creates a million entries with 50,000 duplicates, particularly if the first is about complex topics but the latter is about very simple ones. It's better to ask people to minimise duplicates as much as possible, but not be afraid to create them in complex cases where a human needs to be involved. Thanks.

::I agree with this. Also, for larger datasets, if the newly made items have over 20 referenced statements and the older items less than 5 unreferenced statements, then it is worth the effort to (manually) merge later in order to enrich the data available in the dataset.

:::{{ping|Mike Peel|Jane023}} Do you think we could address this with stating that it is okay for a single bot to create perhaps 100 items at a time, but that it has to stop for the next 100 before the number of duplicates of the last 100 got sufficiently (yet to define) reduced (manually)? Do you have another suggestion for at least a rough standard? Should we decide case by case beforehand, but then what case size needs previous approval? Or do you think the current situation doesn't need reform? I'd appreciate to prevent mass creation of duplicates, but also give bot owners security on what is admissible to do. --[[User:Marsupium|Marsupium]] ([[User talk:Marsupium|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 12:52, 28 April 2018 (UTC)
::::There are two parts to the problem: 1) reducing duplicates on Wikidata and 2) massaging datasets before data upload to reduce the chance of duplicates. Your subject heading implies we can identify duplicates on creation, which is not the case. At best you need an overnight bot run to reveal the dupes. I think guidelines are in order for uploaders so they can both understand the problem and also how to test their data to get a feel for the duplicates. A max or min rate is just nonsense. [[User:Jane023|Jane023]] ([[User talk:Jane023|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:10, 28 April 2018 (UTC)
:::::{{ping|Jane023}} We can: It would even be better to publish (a part of) a dataset outside the main namespace before uploading it to make public testing possible, but actually I had a test run in mind. ([[WD:Bots]] asks for a “test run of between 50 and 250 edits” after writing a RFP at [[Wikidata:Requests for permissions/Bot]].)
:::::To step back a bit: Do you think the mixnmatch_people_creator upload is desirable? If not, how can we prevent uploads like this one in the future? --[[User:Marsupium|Marsupium]] ([[User talk:Marsupium|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:58, 28 April 2018 (UTC)
::::::To answer your first answer, I disagree. You can only see that there is a constraint violation which is not necessarily the same thing as a dupe. To answer your second question, I think it depends. You cannot just generate them, but you can use that output for a good start. It's like VIAF - we don't base biographies on it, but we do want to link the item to it once the item is done.

===Same old, old arguments ignored===
* The first argument forgotten, ignored; NOT including data means that we can not share the data that we omit because of fear. Data not shared is us being in error because we ignore our objective; sharing the sum of all knowledge.

* Another fallacy is that "their" data is to be be better than our data. We talk about acceptable percentages but as it is, our error rate and Wikipedia's error rate is unknown, ignored. When we accept in new data no more than 2%, it means that with a 3% error rate OUR failure is 97%.

* Now consider 100% quality new data but with 6% duplicates, it means that we can compare existing data with the new data. Even with our data having something like 6% errors, we can find what is similar 

* Now consider our 280+ text databases linked together. With no automated consolidation to show that these links are indeed about the same subject. There is a reasonable opportunity to show the likelihood where the errors are.. Now we consider the acceptable rate of duplication in new data. When are we going to consider an acceptable rate of duplication in our own data?

== United States President ==

If a President servers eight years, can he run again in four years after his term was up?

:No. See the [https://www.law.cornell.edu/constitution/amendmentxxii text of the ammendment] that limits the number of terms a president may serve. [[User:Jc3s5h|Jc3s5h]] ([[User talk:Jc3s5h|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:41, 29 April 2018 (UTC)
== create item constraints ==

Item constraint would allow to check if all instances/subclasses of a certain item satisfy a particular constraint, such as:
* having specific properties or specific values. For example:
** all instances/subclasses of {{Q|Q28693603}} should have a {{P|P1122}} property;
** all instances/subclasses of {{Q|Q15593630}} should have a {{P|P306}} property with an instance/subclass of {{Q|Q1406}} as value; 
* having multiple values on specific properties. For example:
** all instances/subclasses of {{Q|Q174666}} should have a {{P|P400}} property with multiple values.
Actually, something similar already exists - {{P|P1963}} or even {{P|P1552}} - but it doesn't check for constraint violations.
What do you think about it?--[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 17:26, 26 April 2018 (UTC)
: You can use SPARQL queries to extract lists of items not respecting some configurations. No need of specific system to do that. [[User:Snipre|Snipre]] ([[User talk:Snipre|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:18, 26 April 2018 (UTC)
::{{Ping|Snipre}}Yes, but I can do that only if I know SPARQL and it's much more effective have exclamation points warnings whenever there is a constraint violation than have to perform a manual query.--[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 19:51, 26 April 2018 (UTC)
:::But the absence of a property is not really a constraint violation, is it; at least in the form we now know it - as something that's broken.

::::{{Ping|Tagishsimon}} {{Q|Q21503247}} treats the absense of a property as a constraint violation. Furthermore, "item constraints" can indicate also other inconsistencies like wrong values, a wrong number of values, etc (just like property constraints). Thank you for pointing out Recoin - I didn't know it and it's a great tool. However, Recoin is based on common usage of properties and it offers only suggestions, while with "item constraint" we are sure that the item lacks a property or has a wrong value or something else.--[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:10, 27 April 2018 (UTC)
::::: Again, when we see how the constraint violation reports are used, I prefer to avoid creation of a system which will generate reports without any care of them. And one remark about constraint definition is that some contraints have so many exceptions that the constraints don't have any sense. So better manage SPARQL queries in the framework of a project or in an user page. And finally constraint violation reports are currently managed by bots and not by wikibase so this will represent some additional work for the rare bot operators doing that kind of job. Again an individual solution is better because it can be tailor-made with SPARQL or directly wit a bot than a general system which won't be used. [[User:Snipre|Snipre]] ([[User talk:Snipre|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 11:30, 27 April 2018 (UTC)
::::::{{Ping|Snipre}} If I understand correctly, there are two problems:
::::::* not enough bots;
::::::* too many exceptions;
::::::As regards exceptions, IMO they are useful because they allow to understand if the constraint is true or should be deleted. Instead, currently it's much more difficult to understand if a {{P|P1963}} or a {{P|P1552}} is effectively valid for all instances/subclasses.--[[User:Malore|Malore]] ([[User talk:Malore|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:51, 27 April 2018 (UTC)
::::::: {{Ping|Malore}} Currently constraint violation reports are supported by bots and not by Wikibase, so yes, we relying on some bot operators and from what I know only 2 bots maintain the current reports. And since several months, we are reducing the number of constraints because we have too many exceptions. Before creating a constraint, you really have to be sure that that constraint is valid and I am afraid that people will just create constraints without looking at the consequences.

== Six months left before Wikidata's sixth birthday ==

Hello all,

Every year since Wikidata went live, on October 29th, 2012, the Wikidata community celebrates its anniversary all around the world. Local groups organize meetups, workshops, share cake and greetings, to celebrate the work of the editors building up the knowledge base and its ecosystem of tools.

Last year, for the 5th birthday, the [[Wikidata:WikidataCon 2017/Documentation|WikidataCon]], first international conference dedicated to Wikidata was organized in Berlin. Waiting for its return in 2019, the local events continue! We encourage the community to meet up, the chapters and user groups to organize events in order to build a Wikidata group in their area. Even if you're just starting editing, or you've never been organizing an event before, you can be part of the Wikidata's sixth birthday!

The events will take place around October 29th, 2018 (it doesn't have to be on this exact day). You can find a lot of information on this page: [[d:Wikidata:Sixth Birthday|Wikidata:Sixth Birthday]]. You will find the list of events that will take place around the world, ideas of formats, ways to get funded, and documentation about organizing events.

We're excited to see many small or big Wikidata events happening everywhere!

If you have any question or need help, feel free to contact me. [[User:Lea Lacroix (WMDE)|Lea Lacroix (WMDE)]] ([[User talk:Lea Lacroix (WMDE)|<span class="signature-talk">{{int:Talkpagelinktext}}</span>]]) 13:09, 30 April 2018 (UTC)
