 Comment @LinneaKarlberg:, @Eva L Vedin:, @Elinor Rajka:, @Azad Karimi: coordinating support votes with ones colleagues is not helpful, the property proposal process is in place for a reason. Abbe98 (talk) 22:34, 7 April 2022 (UTC)

Sorry, we did not know. LinneaKarlberg (talk) 07:19, 8 April 2022 (UTC)

 Comment Considering that National Historical Museums of Sweden ID (P9495) exists and that other properties from SHM are likely to be proposed in the future(places, events, heritage sites, ect) maybe there should only be one property? As far as I'm aware the UUIDs are unique across the various types and even if that wouldn't be the case one could include the type prefix in the id. Abbe98 (talk) 22:40, 7 April 2022 (UTC)

@Abbe98: Sure, that would probably work. Do you have an example of another external identifier that includes several different types so I can check how it works? Is it possible then to change the name and details of P9495? LinneaKarlberg (talk) 07:22, 8 April 2022 (UTC)

Europeana entity (P7704) would be one example. I would imagine migrating/generalizing National Historical Museums of Sweden ID (P9495) by: 1. updating the formatter URL 2. adding the agent prefix to existing values 3. updating the label/description of the property Abbe98 (talk) 10:08, 8 April 2022 (UTC)

 Oppose Per the discussion above, I would suggest generalizing National Historical Museums of Sweden ID (P9495) rather than creating a new property for each type. I cave created a section on the discussion page. Abbe98 (talk) 10:20, 8 April 2022 (UTC)

Hello Abbe98 , It would then be necessary to differentiate "agents" from "object". How would you like to do? (incorporate it into the identifier as a general property? or use an external URL formatter?) We can also consider that each property will be dedicated to the type (less errors with dedicated constraints). It would be necessary to recontact those who have already voted, as well as the voters of the other property, to find out if your idea appeals to them, but with more information. I don't see a URL leading directly to the correct page without using the type (with only the UUID). Example: type:UUID. Cordially. —Eihel (talk) 03:47, 13 April 2022 (UTC)

Hi! I would imagine we would use one of the seven possible prefixes like agent/<UUID> and object/<UUID>. We could also use a generic resolver but there isn't an official one so I think such a solution is less optimal. Abbe98 (talk) 06:48, 13 April 2022 (UTC)

@Abbe98: @Eihel: @LinneaKarlberg: We just had a discussion about this with the Wikidata team at the National Historical Museums of Sweden. Our conclusion is that this property should not be created, and Abbe98's solution (using prefixes) is better. This will include us (WMSE is supporting the museum in their Wikidata work) generalizing National Historical Museums of Sweden ID (P9495) and removing /person/ from the formatter URL and then adding the person prefix to all the existing uses of the property. --Alicia Fagerving (WMSE) (talk) 12:10, 21 April 2022 (UTC)

@Alicia Fagerving (WMSE) I have pinged all the people who voted on National Historical Museums of Sweden ID (P9495). I think we should leave it over the weekend at least but then if there are no one oposing this I can migrate it early next week. Abbe98 (talk) 12:32, 21 April 2022 (UTC)

We at NHM are all on board with this approach instead of several Properties. LinneaKarlberg (talk) 08:09, 29 April 2022 (UTC)

Sounds like an excellent idea. Many thanks Abbe98 . /André Costa (WMSE) (talk) 08:51, 24 May 2022 (UTC)

Thanks everyone, I've started re-defining National Historical Museums of Sweden ID (P9495) and will migrate the existing items using it. --Alicia Fagerving (WMSE) (talk) 12:19, 9 June 2022 (UTC)
