In order to better address translator coverage for major, non-English sources (T94170), it would help to have lists of the most needed translators for each (major) language Wikipedia. See {T96927} for two-year-old dumps of each language Wikipedia's most referenced domains, sorted descending. (Also re: the Swedish list, see P691 and discussion in T94170#2534552.)
For an example of what this looks like for the Swedish Wikipedia,A research write-up was published [[ https://meta.wikimedia.org/wiki/Research:Citoid_support_for_Wikimedia_references | on Meta ]] and resulted in two comparisons of the most cited domains in need of translators [[https://en.wikipedia.org/wiki/Wikipedia:WikiProject_Fact_and_Reference_Check/Most_cited_domains | on enwp ]] and [[https://fr.wikipedia.org/wiki/Projet:Sources/Sources_les_plus_utilis%C3%A9es | on frwp ]]. see P691 and discussion in T94170#2534552We could use the same treatment for the other languages.
1. Sort most referenced domains, descending
2. Compare list against sites that have active translators (either developed specifically for the website or handled by Embedded Metadata translators)
3. Report back
If if would help develop a template,We either need the most cited lists re-dumped (see research pub on Meta for the methods) or that list analyzed against Zotero translators. it would be helpful to start with a list for the English Wikipedia(Either feed each site into the Citoid citation autocomplete tool, but if you have expertise in another language, we can use that tooor use Zotero browser plugins to determine which translator is triggered for the site and whether Embedded Metadata sufficiently cover the site.) Tables like the enwp and frwp linked above wouldn't hurt.
