260614 — Wikibase / Wikidata deep dive

Deep dive on Wikibase (the MediaWiki extension behind Wikidata) as the entity-statement (RDF) far end of the structure and native-query spectra: items and properties, statements = claim + qualifiers + references + rank, stable opaque IDs, and SPARQL (Wikidata Query Service / Blazegraph) including federated queries.

  • findings.md — data model, RDF/SPARQL surface, storage & history, capability profile, INTENT mapping, UC seeds (UC-73UC-75), architecture notes for SHARD-WP-0002, open questions, sources, traceability.

Catalog yield: UC-73 (attach a typed entity-statement / RDF shard, lossy render to a page), UC-74 (graph query the union via SPARQL + federated SERVICE cross-endpoint query), UC-75 (statement-level provenance — references + rank per assertion). Enriched UC-34/58/52/24. Feeds SHARD-WP-0002 T12 (structured/typed page model) and T16 (stable language-neutral identity ≠ label/placement).
