I have historically mapped the keys “wikidata=” and “name=” of restaurants such as McDonalds. According to the OSM wiki name vs brand is the contributor’s pick in this instance.
However, I have just learned about “brand:wikidata=”. Is there a useful difference to use this key with the keys I normally use or would it be redundant?
Like you said, wikidata refers to all branches. So why would it be more or less accurate to use “wikidata” or “brand:wikidata”? Wouldn’t they both be just as accurate?
As always, there is no clear-cut black or white. At McDonald’s, however, I would definitely be at name=McDonald’s brand=McDonald’s brand:wikidata=Q…
