See T171143: Allow accessing Wikidata data in Wikitech

Just discovered this wasn't possible when trying to link Commons to Wikitech via Wikidata... (https://wikitech.wikimedia.org/wiki/Clusters and https://commons.wikimedia.org/wiki/Category:Wikimedia_servers should interwiki to each other) Any chance of it being implemented please?

This task was mentioned in the Bug Triage Hour at the Wikidata Data Quality Days 2022.

The relevant question is: are they on the same cluster as the other Wikimedia projects. If yes let's do it.

@LucasWerkmeister do you know?

Wikidata and Wikitech can access each other’s databases, at least (tested in shell.php). I’m still worried about the Wikitech stability concerns raised in T171143, though.

Can this be done now that Wikitech is a SUL wiki? I don't think not having sitelinks on wikitech-static is a big deal.

This requires making Wikitech a Wikidata client.

The issue of wikitech-static is if some pages use data in Wikidata they may be failed to display correctly in wikitech-static. Some potential solution are described in T100313#10194419.

I don't think wikitech-static not displaying interwiki links is a big deal; if we're having to resort to wikitech-static then most of those links would be broken anyway.

@taavi As the Wikidata Integrations in Wikimedia Projects team, we are happy to review any new changes on the topic (although I can't +2 config changes). I can see you have an open mediawiki-config change, but it's difficult to review without knowing what the next steps will be. I can see you've written some changes are pending answers from T171143, what questions are those, and what impact may the answers make?

If I'm reading https://wikitech.wikimedia.org/wiki/WMDE/Wikidata/Enable_Client correctly we could create the entity_usage tables and then deploy that patch to enable site links.

For enabling non-sitelink features, the main concert raised in T171143 at the moment is how that integrates with wikitech-static. T376400 will eventually resolve that issue, but for now I think a good compromise is to enable sitelinks and leave the rest of the features disabled.

what is the status of this patch?
