CKAN is the Comprehensive Knowledge Archive Network, a non-profit registry of open data. CKAN prepares data and provides access to data in ways that make that data more discoverable and usable.
The government of Italy makes some datasets available through CKAN, including data on immigration; real-time parking in the city of Turin; National Energy Balance; tourist accommodations in various cities; Italian state schools; museums; and more.
The CKAN API provides access to this data. The API is RESTful and returns responses in JSON and JSONP.
