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.

To add only articles to the categories:

{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix}}

To add pages in other namespaces to the categories:

{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|namespaces=0,14}}

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

{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|nocatsame=1}}

To make comparison case insensitive for "different from" category:

{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|ignorecase=1}}

Required

• |property= is the P### of the property. The "P" must be uppercase.
• |value= is the value to use from the template. This would be something like {{{id|}}} or {{{id|{{{1|}}}}}}
• |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 {{hiddencat}} before applying this template.

Optional

• |namespaces= is a comma separated list of the numerical namespaces to apply the template. The default is 0, which is just article space.
• |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.
• |ignorecase= if set to any value will ignore upper/lower case differences between value in template and value in Wikidata when adding pages to a "different from" category.
• |qid= if specified will check a a different Wikidata item than the current article.
• |onlysourced= if set to "yes" will ignore unsourced Wikidata properties, equivalent to Module:WikidataIB's |onlysourced=yes.

For {{MusicBrainz artist}}, which checks MusicBrainz artist ID (P434), the following code would be added:

{{WikidataCheck|property=P434|value={{{mbid|{{{id|{{{1|}}}}}}}}}|category=MusicBrainz artist}}

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

• {{Tracks Wikidata}} for use in template documentation
• {{Wikidata tracking category}} for use in hidden tracking categories
• Category:Wikipedia categories tracking data not in Wikidata
• Category:Wikipedia categories tracking data same as Wikidata
• Category:Wikipedia categories tracking Wikidata differences
