ମଡ୍ୟୁଲ:WikidataCheck

This template allows you to compare a template parameter to a property in Wikidata. It is powered by the Lua module Module:WikidataCheck.

You can call it with: {{WikidataCheck|property=p###|value={{{value|}}}|category=Category prefix|namespaces=0,14}}

• |property= is the p### of the property. The "p" should be lowercase.
• |value= is the value to use from the template. This would be something like {{{id|}}}
• |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.
• |namespaces= is a comma separated list of the numerical namespaces to apply the template in. The default is 0, which is just article space.

Example

For {{MusicBrainz artist}}, the following is the code to add:

{{WikidataCheck|property=p343|value={{{mbid|{{{id|{{{1|}}}}}}}}}|category=MusicBrainz artist id|namespaces=0}}
