What a Passport Really Contains
A robust passport moves beyond glossy brochures and stores structured, verifiable fields: exact material identifiers, quarry or forest of origin, harvest dates, certification IDs, emissions data, finishing recipes, care guidance, and chain‑of‑custody events. Photographs with time and location stamps anchor the story, while signatures from suppliers, inspectors, and ateliers add legal weight. Add batch and lot numbers tied to packaging, and you gain a single source of truth that supports specifications, insurance appraisals, restoration planning, and future resale without guesswork or missing paperwork.
