Open data is structured data made publicly available for download and reuse under specified licensing conditions. Its reuse rights, limitations, and permitted purposes depend on the applicable licence and should not be assumed from mere public accessibility.
The term refers to the public availability, by download, of structured databases. These data may be re-used in a non-monetary way under the conditions of a specific licence, which may in particular specify or prohibit certain purposes of re-use. Open data is not to be confused with unitary public information available on Internet sites, the entire database of which cannot be downloaded (for example case law databases). It does not replace the mandatory publication of certain administrative or judicial measures or decisions already enacted by certain laws or regulations.
