Methodology

Acquisition & Provenance

Available ownership records are reviewed; gaps and unresolved claims remain explicit.

All objects are evaluated against known databases of illicit cultural property, including INTERPOL and the Art Loss Register. Ownership history must be documented to the earliest verifiable point. Gaps are explicitly noted and not inferred, with particular scrutiny applied to gaps between 1933–1945 and post-1970.

Objects are accepted only where legal title is demonstrable. All acquisitions are assigned accession numbers and recorded prior to intake.

Imaging Protocol

Standardized imaging ensures consistency across the archive.

Objects are photographed against neutral backgrounds with calibrated color targets. A minimum of four views are recorded alongside detail images of marks or inscriptions.

Color accuracy is maintained through calibrated workflows, and images are produced in both archival and access derivatives. File naming follows accession-based conventions to ensure traceability.

3D Capture

Selected objects are recorded as three-dimensional data.

Photogrammetry and structured-light scanning are used depending on material conditions. Output models are processed for geometric accuracy and stored alongside source datasets.

Scale is validated against physical measurement. Tolerances are documented. Source datasets are retained alongside processed outputs to preserve evidentiary integrity and allow future reprocessing as technologies evolve.

Cataloging

Records follow established cultural object standards.

Records conform to CCO with mapping to CIDOC-CRM and Dublin Core. Required fields include identification, material, dimensions, and condition.

Descriptions are restricted to observable attributes and documented context. All interpretive content is clearly distinguished and recorded separately to maintain evidentiary clarity.

Preservation

Environmental control and storage protocols are enforced.

Environmental control and storage protocols are enforced to ensure long-term material stability.

Storage environments are maintained within controlled temperature and relative humidity ranges appropriate to material class. Fluctuations are minimized to prevent mechanical stress, corrosion, desiccation, and biological growth. Light exposure is regulated, with ultraviolet and high-intensity illumination restricted to prevent fading and photochemical degradation.

Objects are housed using inert, conservation-grade materials. Direct contact with reactive substances (acids, unstable plastics, untreated wood, or metals prone to off-gassing) is avoided. Supports, mounts, and enclosures are selected to distribute weight evenly and prevent stress on fragile components.
