Wikimedia projects

Should we expand the domain to include Wikipedia language edition (Q10876391)? --Infovarius (talk) 08:39, 10 January 2016 (UTC)

I would say no. This property means the ISO code assigned to a language. Wikimedia projects are not languages and do not have ISO codes assigned to them. The codes they use are based on ISO codes and IETF language tags and we already have Wikimedia language code (P424) for that. In general, we should link to language items where we want to say which language something uses instead of using these properties. The language item will have the ISO codes, IETF language tags, Wikimedia language code and any other information people want. - Nikki (talk) 09:53, 10 January 2016 (UTC)

Allow “reason for deprecation” as qualifier?

Should ISO 639-3 code (P220) be changed to allow reason for deprecated rank (P2241) as a qualifier? See Emilian–Romagnol (Q242648) for an example of a constraint violation that seems legitimate, specifically the statement for P220 on that item. Generally, I’d be interested in people’s thoughts on how to to best model deprecated language codes. See ISO 639-3 deprecations for the full list. There’s five different reasons for deprecating an ISO 639-3 code, and I’m not sure how to model them in Wikidata. Your advice would be appreciated. — Sascha (talk) 16:48, 8 February 2019 (UTC)

• In principle, any property could use that qualifier. The problem with your application is that the "deprecated code" shouldn't have deprecated rank in Wikidata. They would just have normal rank with an "end date" and "end cause". The new code would have preferred rank. If there is none, "no value" could have preferred rank. --- Jura 09:15, 10 February 2019 (UTC)

Like this? It still is getting flagged as a constraint violation. ISO 639-3 code (P220) of Emilian–Romagnol (Q242648) and ISO 639-3 code (P220) of Romagnol (Q1641543) — Sascha (talk) 14:17, 11 February 2019 (UTC)

Yes, more or less. Maybe end cause could be "code split" or something like that, but I'm not really sure about that. I also added "no value" in preferred rank. --- Jura 18:03, 11 February 2019 (UTC)
