One may also add brand:wikidata=* for tag that is equivalent in function. It adds link that is more likely to not be changing but is not human readable as its tag value. There may be special support to display brand:wikidata=* tag in more readable form, it requires access to Wikidata database to get data from https://www.wikidata.org/wiki/Q703557 )
Comparison with wikipedia tag
There is wikipedia=* tag that can be used to provides a link to Wikipedia's article about the specific feature. Note that it is supposed to be used in cases where Wikipedia article is specifically about a given object. For example adding wikipedia=en:Tree is never correct as it is not an article about a specific tree. In the same way adding wikipedia=en:Walmart to a Walmart supermarket is not correct, because it is not an article about a specific supermarket.
