Museums publish two different things about the same artwork: whether the work is in copyright, and whether their picture of it is. OpenPlate reads both, does the arithmetic on the published term, and shows you the sentence behind every point of the score.

live1. Pin the work
Choose the record and say what you are actually going to do with it. The product re-reads the work live and stores a snapshot, so your docket records what the institution said today.
2. Read the arithmetic
Six weighted factors: the institution's own claim, the creator's term, the publication-age rule, the restrictions in their statement, your use, and whether a credit line is even possible.
3. Seal and export
Record the decision into a SHA-384 chain, then export a dated docket as JSON, CSV or Markdown with the credit line and the seal a colleague can re-verify.
