Catalogue raisonné — the scholarly foundation

This release opens a second use alongside the photo library: documenting a body of work as a catalogue raisonné, with the rigour that implies for attribution, prints, and provenance.

Added

• Catalogue screen and artwork record: every work carries its catalogue number, titles, dating, and publication status.
• Agents directory — people, institutions, workshops — with authority identifiers (VIAF, ULAN, Wikidata, ISNI, ORCID), so the file is reconcilable from day one rather than retyped later.
• Attribution: who the work is attributed to, with what degree of certainty, and on which sources. This is the scholarly core of the catalogue and is treated as such — one accepted attribution per work, with the others kept on record.
• Prints: physical objects distinct from the work, with real dimensions, process, paper, printer, and edition (3 / 8, artist’s proofs, closed edition).
• Exhibitions, publications, and citations linked to artworks, to rebuild an exhibition history without keeping it in a separate spreadsheet.
• Provenance: chain of custody with normalised counterparties, rather than free text that resists querying.
• Review screen to validate records before publication, and a signed verifiable certificate of authenticity whose integrity can be checked independently of the software.

Changed

• Behaviour change to be aware of. Provenance carried over from the previous data model is now confidential by default and no longer appears in reports until a human has reviewed it. A migration cannot know what a curator considers publishable, and a purchase price or the identity of a living buyer are commercial and personal data.

  To restore those rows: clear the confidentiality flag on reviewed records in the Provenance tab, or tick inclusion with a reason for a given export. An empty section can be fixed; a disclosed buyer cannot.
