Supported by Etalab, data.gouv.fr hosts the French government's open datasets. The state, local authorities, and private entities pursuing a public mission may upload their datasets as well. Therefore, data recorded in conjunction with a public service mission is the type that may be uploaded into the system for others to browse. The data spans a wide array of French societal information, including tax, demographic, budgets, grants, planning, crime, housing renovations, tourism, elections, agricultural data, and more. As a public service, groups are encouraged to share their datasets so that innovative applications may interpret the data. The data.gouv.fr API requires an API key for access, and all HTTP calls return JSON formatted responses.
