• •Developer released Ex Situ to visualize the movement of cultural artifacts from origin sites to Western institutions.
• •The index maps specific collections categorized as Islamic or Asian art using interactive arcs and hyperlinks.
• •The project currently lacks a clear roadmap for data verification or a formalized process for origin-site partners to contribute corrections.

Ex Situ is a new open-source spatial index that maps the provenance of cultural artifacts held by Western and Euro-American institutions. Unlike traditional museum databases that prioritize current inventory, this tool emphasizes the geographical trajectory from an object’s site of origin to its current repository. The project remains in its early stages with a narrow focus on Islamic and Asian art collections, though the scale of data integration is currently undocumented. Its utility for historians and repatriation advocates depends on the developer's ability to transition from a single-author technical proof-of-concept to a standardized, peer-verified platform.
