Reference corpus and data sources

Every image in the corpus was pulled from a public open-access collection. Each one was checked against a licence allow-list, vetted automatically and by a person, and normalised and vectorised on a workstation at build time. The deployed app contacts none of these sources. It ships the curated result. This page is the working draft of the SOW Task 3 Data Sourcing and Curation Summary.

Data gaps and caveats
What the prototype corpus cannot yet support, and what Task 3 data-sharing agreements should close.

Scythian gold and bronze ornament

Scythian material circulated across the Pontic steppe. Visual category only; the corpus does not assert Ukrainian find-spots.

Cucuteni–Trypillia painted ceramics

The Cucuteni–Trypillia culture spans present-day Ukraine, Moldova and Romania. Open-licensed images come mainly from Romanian collections via Europeana, so the corpus uses them as visual stand-ins. Obtaining Ukrainian museum data under data-sharing agreements is a priority for Task 3.

Eastern-rite icons and ecclesiastical objects

Few open-licensed images of Ukrainian icons exist. The category is filled out with stylistically close Eastern-rite icons, which is a known data gap.

Black- and red-figure painted pottery

Many Greek-style vases were made in Italian workshops. Italy has separate restrictions (CBP Dec. 11-03), so a match here does not by itself indicate a source country.

The corpus holds 40 images or fewer per category, and one designated list covers hundreds of object types. Full-scale use would need institutional data-sharing agreements (e.g. with Ukrainian national museums), 3D models, and find-spot metadata. Photographs of looted material seized in enforcement cases are not public and are deliberately excluded.
