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 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}}

Parameters

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 in. 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.

Example

For {{MusicBrainz artist}}, which checks Sandbox Monolingual text (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:
