Category:Commons category link is defined as the pagename

This is a hidden category. It is not shown on its member pages, unless the corresponding user preference 'Show hidden categories' is set.

This is a tracking category. It builds and maintains a list of pages primarily for the sake of the list itself. Pages are added to tracking categories through templates.

Pages are added to this category by Template:Commons category. It tracks cases where the locally defined link to Commons is the pagename, but it's not the same as on Wikidata, or it is not on Wikidata.
