Show HN: Ex Situ – open-source spatial index of displaced cultural artifacts

A new Show HN project called Ex Situ is serving up one of the internet’s favorite combos: maps, museums, and moral discomfort. The site tracks 145,387 cultural artifacts from 9 museum collections and shows where they originally came from versus where they are now. On paper, it’s a searchable catalog. In the comments, though, it quickly became a giant public airing of historical grudges, missing context, and fascinated doom-scrolling.

The loudest reaction was basically: this is amazing, but where are the rest of the receipts? One commenter immediately wanted to use it to measure artifacts taken from Korea by Japan, only to hit a wall when provenance details for Japanese institutions weren’t there. Another pushed harder, saying the map should show “much more lines” to Moscow too, especially for places like Crimea, accusing the project of focusing mainly on Western and Euro-American institutions. That’s where the drama lives: people loved the idea, but they also wanted the map to go broader, deeper, and hit more politically sensitive targets.

Then came the dark comedy. One user casually dropped that they should read their ancestor’s diaries to see how he “justified bringing back so much stuff to the UK,” which is an absolutely elite way to say, my family may have receipts from the empire era. Meanwhile, another commenter was fully spiraling in the most wholesome way possible: “i’ve been toggling around this site for a good 40 minutes... arrrgggh, i love the internet.” So yes, the vibe was equal parts education, accusation, and online goblin-mode curiosity.
