How to build an artwork provenance timeline
Turn scattered ownership references into a dated, source-linked timeline without inventing continuity between records.
Normalize dates without erasing precision
Store the source wording alongside earliest and latest possible dates. Distinguish an exact transaction date from a publication date, an exhibition range, an undated recollection, or a later inventory snapshot.
Store the source wording alongside earliest and latest possible dates. Distinguish an exact transaction date from a publication date, an exhibition range, an undated recollection, or a later inventory snapshot. Use a source ledger and claim identifiers so another researcher can reproduce the decision, challenge an assumption, and distinguish evidence from interpretation.
Model gaps explicitly
Do not draw an uninterrupted ownership line when the evidence supplies only endpoints. Add a gap row describing the last supported custody, next supported custody, interval, searches attempted, and evidence still needed.

Separate ownership from custody
Dealers, shippers, restorers, museums, repositories, and agents may possess an object without owning it. Record roles precisely rather than translating every appearance into an ownership claim.

Record the boundary of the evidence
End the research record by separating documented facts, supported interpretations, unresolved questions, and disconfirmed leads. A gap is not proof of wrongdoing, and a repeated statement is not independent corroboration when every repetition traces back to the same source.
Retain the source URL or call number, access date, quoted passage, page or image reference, and a file hash when a stable local copy is permitted. This makes the conclusion reproducible and makes later correction possible without rewriting the history of the research.
