Wikidata:Property proposal/identifier in a register

identifier in a register in Germany[edit]

Originally proposed at Wikidata:Property proposal/Authority control

Done: identifier in a register in Germany (P12012) (Talk and documentation)

Description	identifier in a register located in Germany
Data type	External identifier
Domain	various items represented in various German registers
Example 1	BASF (Q9401) → 6000
Example 2	National Research Data Infrastructure (Q61658497) → 703016
Example 3	Air Berlin (Q156829) → 23373
Example 4	ISC Mannheim (Q1654576) → 700478
External links	Use in sister projects: [ar] • [de] • [en] • [es] • [fr] • [he] • [it] • [ja] • [ko] • [nl] • [pl] • [pt] • [ru] • [sv] • [vi] • [zh] • [commons] • [species] • [wd] • [en.wikt] • [fr.wikt].
Planned use	First, adding them to German companies with qualifiers "type of register" and "XJustiz registration court ID"
Number of IDs in source	more than 5 millions only for German companies, but only 20-30 thousands of them have items at Wikidata. So the plan is adding those 20-30 thousands values of "identifier in a register" with qualifiers "type of register" and "XJustiz registration court ID"
Wikidata project	Wikidata:WikiProject_Authority_control

Motivation[edit]

The same motivation as for Wikidata:Property_proposal/type_of_register:

Germany has many registers. Every register has its own register type which is standardized at https://www.xrepository.de/details/urn:xoev-de:xjustiz:codeliste:gds.registerzeichen. To avoid creating many properties for various German registers and for items they represent, we could create just two properties "type of register in Germany" and "identifier in a German register". Then we could add IDs of German companies from German trade register (Handelsregister) using the property "identifier in a register" with qualifiers "type of register" and "XJustiz registration court ID".

Discussion[edit]

Comment I'd rather continue as outlined at Wikidata_talk:WikiProject_Companies/Archive_2#Missing_identifier_properties, i.e. propose to create specific identifier properties or use one of the existing catalog code (P528) or described at URL (P973). --- Jura 09:38, 22 January 2022 (UTC)[reply]
I've answered at Wikidata:Property_proposal/type_of_register. Let's discuss this issue for both properties there. RShigapov (talk) 10:58, 22 January 2022 (UTC)[reply]

Oppose I would want handelsregister IDs to be stored in a way that allows a formatter URL to make it easy for Wikidata's users to look up the country at the handelsregister. The same goes for many other registers. Formatter urls are usually valuable enough to warrent separate properties. ChristianKl ❪✉❫ 07:33, 21 July 2022 (UTC)[reply]
I am not sure I understood your argument with formatter URL. Could you please elaborate on it? The external identifiers at Wikidata can have no formatter URLs for non-open databases, right?..

We cannot provide formatter URLs for the three-part Handelsregisternumbers (Court + Code + ID) because there is no open public database to refer to (handelsregister.de does not yet provide it openly, but it seems it will change soon, and then may be there will be an opportunity to refer to them. Not now though).

I have explained the problem with identifiers in the German commercial register at https://www.wikidata.org/wiki/Wikidata:Property_proposal/type_of_register, please take a look at it. RShigapov (talk) 07:49, 25 July 2022 (UTC)[reply]

Is there another example of a property like this, where multiple types of identifiers use the same property? Harej (talk) 15:09, 2 July 2023 (UTC)[reply]
