01
Physical identity
Craft marks, serial references, material documentation, production records, and atelier information may contribute to the physical identity of an object. The relevant signals depend on the object category.
02
Documentary and historical identity
Certificate information, creation date, collection, commission reference, authorized documentation, restoration history, and archive references connect an object to its story.
03
Digital evidence with limits
Digital records can complement physical evidence. They should not automatically replace it, and a ledger cannot make unsupported physical information true.
