Support subject:wikidata and subject:wikipedia for historic=memorial and tourism=artwork

[matkoniecz]

It is really popular to misuses wikipedia and wikidata tag for linking to depicted events.

See https://wiki.openstreetmap.org/wiki/Key:wikipedia#Secondary_Wikipedia_links

For example https://www.openstreetmap.org/node/4835533107 is not a synagogue burnt down by Germans (it is not existing anymore) but a memorial.

Unfortunately correct tagging using subject:wikipedia and subject:wikidata is currently not supported by iD.

I'd theoretically be fine with generalizing the Wikidata/Wikipedia fields for use with keys like subject:wikidata and brand:wikidata. My main hesitation is confusing new users with fields with names like "Subject Wikidata", but perhaps that's not a big deal if we put these in "moreFields".

I agree with @quincylvania .. My thought on this is not that it's hard to add them, but more that it's hard to explain to users which ones to use.

Maybe "Wikipedia about artwork subject"/"Wikipedia about memorial subject"?
