A small, structurally complete sample of the Biodiversity Heritage Library RDF: whole titles with all their items, pages, parts and creators. Same schema as the full 'bhl' dataset, counts are sample counts. Meant for schema discovery and tools that run whole-graph queries.

Bibliographic metadata from the Biodiversity Heritage Library (biodiversitylibrary.org) — items, titles, creators, parts, subjects, and page-level scientific name mentions, converted from BHL's official data.zip export.

Erdera test set
