Provenance helps collection holders make visual collections easier to find and use while source records stay authoritative.
Start with one collection, one representative sample, and one defined problem.

In a Provenance workflow, a model can propose a caption, labels, and a confidence score from each source record. A curator can review those fields before they are reused. Approved records can then support semantic search and related-image browsing.

Keep the source intact.
Generated fields can support search and research without replacing the source record. Each layer stays separate, reviewable, and traceable.
- 01
// Source
Original files, identifiers, and metadata remain intact.
- 02
// Enrich
OCR, captions, and search details are added beside the source record.
- 03
// Review
People can inspect, correct, accept, or reject generated information.
- 04
// Use
Approved information can support search, research, interfaces, and exports.
Start with a bounded pilot.
Before a larger implementation, we work with a representative slice of the collection and one clearly defined problem.
