Mix'n'match

I have added all people on the OpenPlaque site to Mix'n'match, amd am synchronizing ~3K entries to Wikidata now. Finding and matching more entries should be much easier there than on Wikidata. --Magnus Manske (talk) 15:57, 24 July 2014 (UTC)

Why only humans?

There are plaques for groups of humans, and non-human entities. Why limit it to people? --Magnus Manske (talk) 07:59, 25 July 2014 (UTC)

Shouldn't this property be used on items about the plaques?

The identifier is pointing to a website with information about the plaques, so why attach it here to items about non-plaques? I think using it on items about the plaques would make more sense, and it would address issues of plaques related to groups of people, events and other stuff. --Daniel Mietchen (talk) 13:26, 4 November 2017 (UTC)

Oops — I just noticed that there is Open Plaques plaque ID (P1893) as well, which addresses my point. Sorry for the noise. --Daniel Mietchen (talk) 13:29, 4 November 2017 (UTC)
