{{Q|Q21510860}} specifies that values for a property should be within a certain range or interval. This constraint is available for quantity or date properties.

For example, {{P|P1102}} is always between 0 or 1 (within the interval <math>[0, 1]</math>), and {{P|619}} should not be before {{ISOdate|1957-10-04}}.

WikibaseQualityConstraints normalizes all quantities (applies unit conversion) before checking this constraint.
For example, a mass of 500 g will be considered to lie within the range of <math>[0~\mathrm{kg}, 1~\mathrm{kg}]</math>, although 500 is not within the range <math>[0, 1]</math>, because the range endpoints are converted to <math>[0~\mathrm{g}, 1000~\mathrm{g}]</math>;
on the other hand, a duration of 100 days will be considered to lie outside the range of <math>[0, 5000]</math> (note the missing units) because it is interpreted as 8640000 seconds.

If no {{P|4680}} is specified, this constraint is checked everywhere.

== Możliwe działania ==

There are several possible ways to address a violation of this constraint:

* It’s possible that the value in the statement is incorrect (e. g. due to confusing the thousands separator with the decimal separator) and should be fixed.
* It’s possible that the current item should not have the statement at all, and that the statement should be removed.
* It’s possible that the item is a rare, but legitimate exception to the constraint, and nothing should be done.

== Parametry ==

On “quantity”-type properties, the following two parameters are mandatory:

; {{P|P2313}}: The lower boundary of the permitted range. {{no value}} can be used to specify a range with no lower boundary (<math>(-\infty,n]</math>). {{unknown value}} is not permitted.
; {{P|P2312}}: The upper boundary of the permitted range. {{no value}} can be used to specify a range with no upper boundary (<math>[n,+\infty)</math>). {{unknown value}} is not permitted.

On “point in time”-type properties, following two parameters are mandatory:

; {{P|P2310}}: The lower boundary of the permitted range. {{no value}} can be used to specify a range with no lower boundary (<math>(-\infty,n]</math>). {{unknown value}} means the current date at the time the constraint is checked.
; {{P|P2311}}: The upper boundary of the permitted range. {{no value}} can be used to specify a range with no upper boundary (<math>[n,+\infty)</math>). {{unknown value}} means the current date at the time the constraint is checked.

In both cases, the interval is always inclusive on both ends: the minimum and maximum value are both permitted values.

==Examples==
=== Example 1 ===
Example setting for {{P|P1086}}. 
{{Statement+
|P={{P-|P2302}}
|V={{Q-|Q21510860}}
|V1.q1.p = {{P-|P2313}}
|V1.q1.v1 =0
|V1.q2.p = {{P-|P2312}}
|V1.q2.v1 =155
|reference=close
}}

=== Example 2 ===
Example setting for {{P|P813}}. "15 January 2001" is the day when Wikipedia went online ([[:w:Wikipedia:Wikipedia Day|Wikipedia Day]]). "{{Unknownvalue}}" is added to statements by clicking on the icon beside the value field that looks like this [[File:Wikidata snak icon.png]].  "{{Unknownvalue}}" is interpreted as "now".
{{Statement+
|P={{P-|P2302}}
|V={{Q-|Q21510860}}
|V1.q1.p = {{P-|P2310}}
|V1.q1.v1 =15 January 2001
|V1.q2.p = {{P-|P2311}}
|V1.q2.v1 ={{Unknownvalue}}
|reference=close
}}

==Template==
When the constraint is set to the property, the following template is automatically displayed in the property talk page. The template is created by [[Module:Constraints]] using [[Template:Constraint]], invoked from [[Template:Property documentation]]. Translations are defined at [[Module:i18n/constraints]].
