- I could not find a way to link to a relevant page based on the id. This property does not have a URL pattern either. I have removed the URLs, and thus the links, which are now plain text. If you know of a URL pattern I could use, please let me know. --Magnus Manske (talk) 15:15, 20 July 2017 (UTC)
Standards
editThere are two different standards, with two different number series, ISCO08 from 2008 and ISCO-88 from 1988. This property does not say which one it follows. The example for librarian (Q182436) uses 2622 which matches ISCO-08, playwright (Q214917) uses 2451 which matches ISCO-88, stonemason (Q328325) uses 2452 but should be 7113 for ISCO-08 or 7122 for ISCO-88. In short it seems like a mess. Jeblad (talk) 11:22, 14 May 2020 (UTC)
- My intention is to change this property to cover ISCO-88 if/when Wikidata:Property proposal/ISCO-08 occupation code is accepted. Jeblad (talk) 13:31, 26 May 2020 (UTC)
- I've been working down the following query https://w.wiki/5dgM to check every item with an ISCO-88 value and make sure it also has an ISCO-08 value (and that both are correct), and checking the relationships against the official comparison tables available here (downloadable .dcx file).
- Unfortunately Mix'n'match catalogue 148 had data for ISCO-08 but had been associated with this property instead. I hope that misalignment is now corrected, but it has left a lot of clean up to do. I've been finding maybe 50% of current P952 values should actually have been ISCO-08 occupation class (P8283) ones. -- Jheald (talk) 20:23, 29 August 2022 (UTC)
Change data type to identifier
editThe data type of this property is currently "String", but IMO it should be "External identifier". Assuming this is correct, how can I request that change? /cc Teolemon, TomT0m, NMaia (fka Pikolas), and Danrok, from the property proposal discussion. --Waldyrious (talk) 14:40, 20 January 2022 (UTC)
- @Waldyrious: No. Per wikidata's current practices, it is correct that the type of this property is not "external identifier", and that it appears in the main section, not the external identifiers section.
- The reason is that wikidata uses this property as a classification not an identifier. The difference is that (except in rare circumstances) an identifier should identify a single item; other items should not have the same value of the identifier.
- But for P952 this is not the case: the way we use P952 we do not expect different items to have different values. Instead we use P952 as a classification. All items for different occupations in the same ISCO-88 group should have P952 statements with the same value. So potentially there may be many items, all with the same P952 value, and this is fully expected behaviour.
- It is to try to be a clue to users to try to help flag this that P952 appears in the main section, not the external identifiers section; and that it has type 'string' rather than 'external identifier'. Hope this helps, Jheald (talk) 20:35, 29 August 2022 (UTC)
- Thanks for the response, Jheald. The rationale you've described makes sense to me, but perhaps we should use a name for the property that better describes its meaning — "occupation" is generally understood to represent a single profession, not a broad category of professions. Similarly, the "code" at the end of the name creates ambiguity as it's commonly used for identifier-type properties. I would find it more intuitive if this property was named "ISCO-88 occupation class", for example. WDYT? --Waldyrious (talk) 08:30, 30 August 2022 (UTC)
- Makes sense; & keep the existing label as an alias. Jheald (talk) 13:34, 30 August 2022 (UTC)
- Done. We can always revert it if people don't like it. Jheald (talk) 16:19, 30 August 2022 (UTC)
