[[Template:WikidataCheck]] compares a template parameter to a Wikidata property and adds pages using the template to one of three categories: not in, same as, or different from Wikidata. It is powered by the Lua module [[Module:WikidataCheck]].

== Usage ==
To add only [[Wikipedia:What is an article?#Namespace|articles]] to the categories: 

<code><nowiki>{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix}}</nowiki></code>

To add pages in other [[Wikipedia:Namespace|namespaces]] to the categories: 

<code><nowiki>{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|namespaces=0,14}}</nowiki></code>

To prevent adding pages to a "same as" category:

<code><nowiki>{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|nocatsame=1}}</nowiki></code>

== Parameters ==
; Required
* {{para|property}} is the P### of the property. The "P" must be uppercase.
* {{para|value}} is the value to use from the template. This would be something like <code><nowiki>{{{id|}}}</nowiki></code> or <code><nowiki>{{{id|{{{1|}}}}}}</nowiki></code>
* {{para|category}} is the prefix to use in front of the category names. The categories created are "[prefix] not in Wikidata", "[prefix] same as Wikidata", and "[prefix] different from Wikidata".
** It is recommended you create these categories with {{tlx|hiddencat}} before applying this template.
; Optional
* {{para|namespaces}} is a comma separated list of the numerical namespaces to apply the template in. The default is 0, which is just article space.
* {{para|nocatsame}} if set to any value will prevent adding pages to a "same as" category. The "not in" and "different from" categories are still added, where applicable.

== Example ==
For {{tlx|MusicBrainz artist}}, which checks {{property|P434}}, the following code would be added:

<code><nowiki>{{WikidataCheck|property=P434|value={{{mbid|{{{id|{{{1|}}}}}}}}}|category=MusicBrainz artist}}</nowiki></code>

Articles using that template with an ID would be placed in one of the following categories:
* [[:Category:MusicBrainz artist not in Wikidata]]
* [[:Category:MusicBrainz artist same as Wikidata]]
* [[:Category:MusicBrainz artist different from Wikidata]]

== See also ==
* {{tl|Tracks Wikidata}} for use in template documentation
* {{tl|Wikidata tracking category}} for use in hidden tracking categories
