Description

The WDQS docs on mediawiki.org and wikidata.org have some duplicated content about federated queries and endpoints, which is making it a bit confusing to navigate. Below is a brief summary of my ideas for how to combine them:

(keep this section but update it after cleanup work is done) Wikidata:SPARQL_query_service#Federated_queries This section currently links to several different pages. After this task is complete, this section should be able to link to just Wikidata:SPARQL_query_service/Federated_queries, the main page about federated queries. All the other links currently in this section should be linked to from within Wikidata:SPARQL_query_service/Federated_queries.
(keep this page as the main page for the topic) Main federation overview page, with how to and examples: Wikidata:SPARQL_query_service/Federated_queries
(keep this page as-is) Report of endpoint functionality : Wikidata:SPARQL_query_service/Federation_report
(move or delete section content) mw.org User Manual section on federation Verify that the information in this section is covered by Wikidata:SPARQL_query_service/Federated_queries or one of the other wikidata.org pages listed above. After verifying that the information is covered, remove this section from the mediawiki.org page.
(deprecate) mw:Wikidata_Query_Service/User_Manual/SPARQL_Federation_endpoints - Mark this page as {{historical}}. Since it's a manually duplicated version of the config in Gerrit, and Wikidata:SPARQL_query_service/Federated_queries/Allowlist is a more authoritative source for this topic, we shouldn't manually maintain additional data on this page separate from those other pages.

If the above changes are made, then all the information about query federation in WDQS would be on wikidata.org, with all related content moved off of mediawiki.org.

Note that information about federation strategies within the Wikibase software is out of scope for this task, so the following pages should remain on mw.org:

Thank you for tagging this task with good first task for Wikimedia newcomers!

Newcomers often may not be aware of things that may seem obvious to seasoned contributors, so please take a moment to reflect on how this task might look to somebody who has never contributed to Wikimedia projects.

A good first task is a self-contained, non-controversial task with a clear approach. It should be well-described with pointers to help a completely new contributor, for example it should clearly point to the codebase URL and provide clear steps to help a contributor get set up for success. We've included some guidelines at https://phabricator.wikimedia.org/tag/good_first_task/ !

Thank you for helping us drive new contributions to our projects <3

Hi! I would like to work on this task. I will first compare the existing federation documentation on mediawiki.org and wikidata.org, then consolidate the content as described in the task. Is there anything I should be aware of before I start?

Hi! I’d like to take ownership of T436564 and work on this task. I noticed Vanshika has expressed interest as well. If she has not started working on it yet, would it be okay to assign the task to me? I’m ready to start and will coordinate to avoid duplicate work.

Hi,

I’ve completed the following changes for T436564:

Removed the duplicated “Federation” section from the MediaWiki Wikidata Query Service User Manual.
Marked the “SPARQL Federation endpoints” page as historical using {{Historical}}.

The main Wikidata SPARQL query service page is protected, so I’ve posted the proposed cleanup on its Talk page for maintainer review.

Thanks!

Thank you @Karthiktelagi for working on this task! I didn't realize the Wikidata SPARQL query service page was protected; sorry about that. I'm not sure what the requirements are to get autoconfirmed status on Wikidata, but since it might require making edits to Wikidata items (which is far beyond the scope of this task), I'll go ahead and make the changes to the Wikidata SPARQL query service page.

Thanks! No problem at all. I’m glad I could help with the documentation changes. I’ll leave the protected-page update to you.

Please take a look at these edits and if everything looks good to you, go ahead and mark this task as Resolved.

Thanks again!

Thanks! I reviewed both changes and everything looks good. Marking T436564 as Resolved.
