Consider making this a Z2 key so that any persistent object can reference a corresponding Wikidata item.

This would effectively be a secondary identity key, which we'd previously hand-waved-for-now and said we weren't yet supporting. Not sure of the implications in our orchestrator code, if any.

I think we'd rather implement this via identity keys with specific semantic intent and a one-to-one mapping, rather than a catch-all "roughly the same as". For instance, Q32043 ("addition") would be the target of many Functions – one that takes two Integers, one that takes five, one that takes two floats, one that takes a vector of hypercomplex numbers, etc..

@Jdforrester-WMF Hmmm… “specific semantic intent” is good, but a link at the Z2 level is a semantic copula. It specifically asserts identity, not “roughly the same as”. Accordingly, it is much more likely to be appropriate for types and identities than for functions, implementations and tests.

I’m not sure I recall the specific hand-waving around secondary identities. In my view, Wikidata is the natural repository for these, so I would expect support for them to grow out of Wikidata integration. However, I consider Wikidata identifiers to be a special case, not least because their status as secondary identifiers is debatable at the WMF level (although they are clearly secondary outside of Wikidata, in the physical sense).

The Z60 case is a special special (special?) case, of course… but one way or another, I continue to agree with @Mahir256.

As part of a backlog review, we’re looking at tasks in the Product Backlog that haven’t had activity in the past 12 months to help keep priorities clear and up to date.

We plan to move this task to “No Current Plans” after 15 May 2026. If you believe this task is relevant right now, please comment and provide context on why before then.

Many thanks!

In Abstract Wikipedia, text that is not in the target language should be accompanied by a reference to the alternative language, for example: as a link, as text or as a footnote. Without a link from the Natural language to its Wikidata item, none of these options is viable. Z29749 is one of the most widely used functions on Abstract Wikipedia (called from over 400 pages but prefixing the Latin script language tag (when required) produces unsatisfactory rendered content in any language. The same approach is also adopted by the Z11 display function, Z21583, leading to unsatisfactory results for any embedded function that returns Monolingual text, when the result is not in the requested language.
