[copied from my talk page]

Hi! I have just discovered the existence of Kalliope-Verbund (GND) ID (P9964); just about 100 uses, surely redundant with GND ID (P227) (it was noticed by Jura in the proposal, in fact, but it was nevertheless created). I'm thinking of proposing its deletion ... would I be wrong? Thanks, --Epìdosis 16:01, 1 April 2023 (UTC)

Kalliope uses GND but it's an independent database = de:Vorlage:Kalliope. I don't know why Wikidata property example (P1855) only shows GNDs. There are other identifiers like CH-002121-2-991170522280805501 = Sokrates und das Göttliche von Hans-Georg Gadamer. Imho formatter URL (P1630) (and the values?) needs to be corrected. --Kolja21 (talk) 22:22, 1 April 2023 (UTC)

OK. As of now the property is scoped for humans and organizations; they are all present in GND, right? If so, we could erase all the present values of the property (you could propose in the property talk page) and rescope it for documents. Would you agree? --Epìdosis 13:10, 2 April 2023 (UTC)

Hm. To be honest, I’m struggling to come up with ideas that wouldn’t create more problems than they solve … --Emu (talk) 14:31, 2 April 2023 (UTC)

Possible course of action:

• https://kalliope-verbund.info/gnd/$1 should be changed to https://kalliope-verbund.info/$1
• The values needs to be corrected

Imho we should be able to use this property for humans, organizations and documents. (The German template has two parameters: person and object.) --Kolja21 (talk) 14:41, 2 April 2023 (UTC)
