Wikidata

This document registers Wikidata's public SPARQL endpoint as a source Quick Search can query: the canonical example of a Source Definition — what a family member gets when they pick "Wikidata" from a source picker instead of typing a URL.

The endpoint accepts unauthenticated, cross-origin browser requests, so it is registered with sdg:accessMode sdg:DirectAccess: a client queries it straight from the browser, no relay involved.
