"Slug" rather than "ID"

Although FragDenStaat actually has numeric IDs, we use this property to enter the slug as it appears in the URL. --Nw520 (talk) 12:19, 4 October 2020 (UTC)

New property for IDs?

Lately, numerical IDs have become part of the canonical URLs for government agencies in FragDenStaat (although they already existed before in the API). Should a new property be proposed to migrate to these numerical (and probably more stable) IDs? --Nw520 (talk) 15:05, 16 December 2021 (UTC)

@Kristbaum: as proposer of this property: Lately, FragDenStaat has changed the format of its URLs such that it now contains both the numerical ID and the slug of government agencies. Should this property be repurposed to use the (probably more stable) numerical ID (formatter URL (P1630) wouldn't have to be changed for this)? If not, then URL match pattern (P8966) should be updated since lately contributors have been addings IDs rather than slugs to Wikidata. --Nw520 (talk) 00:22, 25 January 2022 (UTC)

@Nw520: The numeric ID would probably be more stable in the long run, so we should change the property to prefer them. Is there anyone else that should be consulted, or should we just do it? And is there an official position of FragDenStaat on the long term stability of the slugs?  – The preceding unsigned comment was added by Kristbaum (talk • contribs) at 22:26, 31. Jan. 2022 (UTC).

@Kristbaum: Thanks for the reply! The main developer of FragDenStaat stated that the numerical IDs are to be preferred. He also mentioned that using slugs might lead to problems with stability. Therefore, I propose to:

• rename this property back to FragDenStaat public body ID  Done
• update formatter URL (P1630)  Done
• update URL match pattern (P8966)  Done
• update property constraint (P2302)'s format constraint (Q21502404)  Done
• and most importantly migrate all current slugs in Wikidata to their numerical counterparts.  Done with toollabs:editgroups/b/CB/c090aa53f38
• The Mix'n'Match catalogue will also need to be updated, which I cannot take care of.

I don't know of any other parties which need to be consulted and I highly doubt that there are. This migration is only a breaking change if your using the slugs with FragDenStaat's API. URLs of FragDenStaat work with both types of identifiers. --Nw520 (talk) 12:01, 1 February 2022 (UTC)
