Regione Lombardia Open Data publishes 100 open datasets for Italy. Browse them live in Vizzie and turn any one into a map or chart.
Regione Lombardia Open Data is the open-data portal for Italy, covering Lombardy. It runs on Socrata, Tyler Technologies' open-data platform. You can browse it directly at dati.lombardia.it.
On Regione Lombardia Open Data, most datasets here are clearly licensed — only a small share are undeclared. It's important to know that "no licence declared" is not the same as public-domain or free-to-use. Undeclared data carries no explicit permission to copy, adapt, or redistribute it — so reusers should treat it cautiously and check with the publisher before relying on it. Vizzie flags each dataset's licence (or its absence) so you can see this before you build.
Of the 97 datasets here whose licence Vizzie can identify, essentially all of them can be used commercially. Attribution is required by almost every open licence — Vizzie writes the attribution line for you when you export or publish.
4270 datasets, 100 sampled live 19 Sep 2026.
Regione Lombardia Open Data doesn't expose a machine-readable breakdown of who publishes what, so there's no reliable publisher ranking to show here. Vizzie still surfaces each dataset's own publisher as you browse.
