Work on etherpad at: https://etherpad.wikimedia.org/p/2026.03_Wikibase_SPARQL_Prefix_%40_WMHack (the etherpad will likely be removed after a period of time, see below for a copy in a Phabricator paste).

We'd like to end the hackathon with a clearly documented decision about what this should look like so we can then put it in front of @Lydia_Pintscher and/or Wikidata Platform Team.

Notes from the hackathon preserved in P89860.

Sub-tasks that Document Decisions, Motivation and Impact

T419994: Add a `wb` SPARQL prefix-prefix automatically to refer to the current wikibase

More potential decisions have been documented in the etherpad Phabricator Paste but are not complete / decided upon.
