Included

A useful public baseline

  • Stable work slug, title, year and type
  • Primary creator and source country
  • Status, public domain date and confidence for six jurisdictions
  • Export date and licence metadata

Not included

The enriched layer

Detailed rule traces, citations, warnings, relationships, bulk updates, change feeds, API convenience and support are not part of the basic export. Those capabilities can support paid products without restricting reuse of the public baseline.

Catalogue provenance

Real records, explicit limits

The catalogue includes 17 hand-curated records and 6,721 imported creative works. Each imported work has a Wikidata structured record with a publication date and a named creator whose death date is recorded. Project Gutenberg identifiers are retained as a second-source cross-check when available; they are not required for inclusion because Gutenberg does not provide original publication dates for every work.

Repeatable exports

Built for scheduled updates

The same verified run prepares 6,738 per-work files, 2,855 creator files, six jurisdiction metadata files, yearly indexes and a 40,428 row database batch covering every work-country pair. Uncertain identity matches are held for review instead of being published automatically.
