Withdrawn by proposer (too many proposals)

  • Problem: In the following cases, wikidata cannot provide inter language link information:
    • When there are multiple articles (written in different scripts or such) exists in same wiki project, thus cannot be linked into same wikidata entry due to current limitations
    • When one wiki created an article for broader concept however another wiki only created article for smaller subdivided concepts and thus they cannot be linked together directly
    • When one wiki created an article for concept A, and then another wiki created an article for concept A', where each of them are related and the detail of the subject of the other article are more or less introduced in the page, however they cannot be linked into same wikidata entry as both A and A' have their separate wikidata entry
  • Who would benefit:

All wiki users that use interlanguage links

  • Proposed solution:
    • Enable input of multiple values for same language in each wikidata entry
    • When there are wikidata statement that claim close relationship between two different wikidata items, or when there are explicit properties for wikidata items saying it should be the case, display interlanguage link from other wikidata items in wiki UIs
  • More comments:

In case it's not clear enough, the proposal cover the following situation:

    • Enable linking multiple pages for same language for the same wikidata item (possibly with statement about nature of each of those links)
    • Enable display of inter-language link from multiple different wikidata items for any given wiki page
    • Enable relating information of different wikidata entries
  • Phabricator tickets: T54564 and many others

  • I think it would be better (than to allow linking multiple articles on a wiki to the same item) to (1) label pairs or groups of items as not having one-to-one relationships; (2) establish a way to link redirects on the relevant wikis to those items. In general, Wikidata items are supposed to represent singular concepts; (to use the typical example) it wouldn't really make sense to link both qqq:Bonnie Parker and qqq:Clyde Barrow to Bonnie and Clyde (Q219937), because items already exist for Bonnie Parker (Q2319886) and Clyde Barrow (Q3320282). Having three separate items, with one item to represent the pair, makes it much easier to represent data for each of those things in Wikidata (e.g. dates of birth; what those items actually represent – human (Q5) and duo (Q10648343)), at the expense of requiring redirects for interwiki links.

    • If you are talking about the first sub-point, then that is referring to situations when there are multiple articles created on same wiki for exact same concept, unlike what you describe which would fit the other sub points more. I am not saying that a single approach should be adopted for all these situations but that different approaches should be developed to resolve all these different problemsC933103 (talk) 20:12, 30 October 2018 (UTC)
      • @C933103: I forgot about the permanent duplicated items. For those the current solution is clearly not as useful, but I would think it would be best to only allow some number of sitelinks for wikis with multiple versions (e.g. hak-Hant:台灣 and hak-Latn:Thòi-vân), with that number being the amount of language variants.

    • Bonnie and Clyde is not a typical example but an exceptionally clear case. Life isn't that easy. We have en:Concentrated solar power with very few interwiki links and de:Sonnenwärmekraftwerk (solar thermal power) with lots of interwiki links. Both articles are mainly about the same (concentrating) types but the latter also includes non-concentrating designs, which are of low importance and mentioned in the English article only under ==See also==. So it's not the very same concept, but nevertheless, all those articles should be interwiki-linked. --Rainald62 (talk) 20:46, 30 October 2018 (UTC)
      • @Rainald62: In that case I would think the solution (with the current software) would still be to create redirects like w:en:Thermal solar power station and link them to the other item, if both concepts are covered within the same item. However, I have proposed d:Wikidata:Property proposal/also display sitelinks for, which would probably be helpful (I have no idea why this property doesn't exist yet).

      • I think merging en:Concentrated solar power and de:Sonnenwärmekraftwerk into a new item, and marking them with two different colors could be a solution. --Leiem (talk) 15:43, 1 November 2018 (UTC)
        • What about when, for example, if a random small Wikipedia created article for both items already? Do you think it's better to merge both of them together, or do you think it is better to keep them as separate while items in both wikidata items get linked across? Both methods would be helped by improvement requested in this proposal. C933103 (talk) 05:08, 3 November 2018 (UTC)
    • Unlocking the ability to link a Wikipedia redirect to a Wikidata item would really help, but I understand that such a change does not have consensus at Wikidata. enwiki has been forced to implement a workaround, which works when the Wikidata label matches a redirect to the correct topic, but it causes bad links when the label matches an unrelated topic or a disambiguation page or a redirect to either of those.

      @Certes: The RfC on allowing sitelinks to redirects was recently closed with consensus to allow sitelinks to redirects (see d:Wikidata:Project chat#Inclusion of redirects, the post-RfC thread). Jc86035 (talk) 16:11, 8 November 2018 (UTC)
