Module:WikidataCheck
 | This Lua module is used onapproximately 488,000 pages, or roughly 1% of all pages. To avoid major disruption and server load, any changes should be tested in the module's/sandboxor/testcasessubpages, or in your ownmodule sandbox.The tested changes can be added to this page in a single edit. Consider discussing changes on thetalk pagebefore implementing them. |
 | This module issubject to page protection.It is ahighly visible modulein use by a very large number of pages, or issubstitutedvery frequently. Because vandalism or mistakes would affect many pages, and even trivial editing might cause substantial load on the servers, it isprotectedfrom editing. |
 | The following is the documentation forTemplate:WikidataCheck. |
Template:WikidataCheckcompares 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 moduleModule:WikidataCheck.
Usage
To add onlyarticlesto the categories:
{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix}}
To add pages in othernamespacesto 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 comparisoncase insensitivefor "different from" category:
{{WikidataCheck|property=P###|value={{{value|}}}|category=Category prefix|ignorecase=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.
- It is recommended you create these categories with
- 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 toModule:WikidataIB's|onlysourced=yes.
Example
For{{MusicBrainz artist}},which checksMusicBrainz 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
