Wikidata - extending/update allowlist Federation
Open, MediumPublic

Description

Some of the urls in the allowlist for federated queries are no longer working, others seem like good candidates to add to the allowlist. There is currently no way to suggest changes.

We need a procedure to suggest new servers.

Event Timeline

Via a deprecated (?) documentation page I found instructions to create requests via Phabricator like this: T398820: Add RKD to WDQS allowlist (this is a real request)

It would be good to clarify and update https://www.wikidata.org/wiki/Wikidata%3ASPARQL_federation_input (or deprecated and redirect it) and update the procedure so that it's clear what people like us need to do today :-)

Thank you!

@Lydia_Pintscher Do I understand right that the problem in this ticket is that the procedure to suggest changes to the Allowlist is too obscure, which could be addressed by the update of the WIkidata documentation?

Yes plus that the list contains endpoints that don't work any longer.

BTracy-WMF moved this task from Incoming to Wikidata / Wikibase on the Wikidata-Query-Service board.

Update:
The new process for nominating endpoints is live: https://www.wikidata.org/wiki/Wikidata:SPARQL_query_service/Federated_queries/Allowlist
The process for cleaning the list from non-operational endpoints is in development.
