heirs (Q29902355) is not a valid value

@Hannolans:The values of this property are specific legal persons and heirs (Q29902355) is not a specific legal person. If two people have the same copyright representative (P6275)-value, they are supposed to be owned by the same copyright holder. That assumption is broken when you enter values like heirs (Q29902355). You would need an item like "heirs of XY". ChristianKl ❪✉❫ 10:03, 14 December 2019 (UTC)

many museums use 'heirs'. we could create an item for every artist but that would mean we will end up with 100000s of heirs-items that are not persons but an unknown configuration of family members. We also have 'anonymous' and 'unknown' as creators, we don't create items 'unknown creator of ...'. Heirs could be the same concept in my opinion. It gives some important information without creating those items. --Hannolans (talk) 10:10, 14 December 2019 (UTC)

Ha in this siituation of Naum Gabo (Q309482) I admit you are right, it was not stated as 'heirs' but as 'Nina & Graham Williams'. So that are individuals and we could create items for them. --Hannolans (talk) 11:01, 14 December 2019 (UTC)

Wikidata has a very different data-model then a museum who basically models their data as strings. Wikidata actually has a sane ontology that distinguishes a legal person from a class of legal persons.

When it comes to unknown creators, there's "unknown value" in the Wikidata model. You could use "unknown value" for heirs with the qualifier object has role (P3831) heirs (Q29902355). ChristianKl ❪✉❫ 19:27, 15 December 2019 (UTC)

currently for unknown creators we use anonymous (Q4233718) and there is also a discussion between 'unknown' and 'anonymous' we have to solve. That is also the case for heirs as there identity might be known by the museum but not disclosed because of privacy. --Hannolans (talk) 08:50, 18 December 2019 (UTC)
