Politecnico di Milano Open Data
The university's own open data portal. It is not CKAN, Socrata or a data.json endpoint — all three 404 — but a DCAT-AP_IT catalogue serialised as RDF Turtle at /opendata_polimi.ttl, declaring 25 datasets each with a CSV and a JSON distribution at a stable, unauthenticated URL. All 25 JSON distributions were fetched successfully on 2026-09-01, returning 38,255 rows in total. Every distribution is CC BY 4.0. JSON bodies are UTF-8 with a byte-order mark and wrap rows in a single `recordset` array. An earlier profile of this institution recorded "no documented programmatic API" here; that was a probe-vocabulary failure, not an absence.
