Pourquoi n'y a-t-il pas de consensus sur une licence open data en France

By September 2011, the French open-data movement had its national portal — data.gouv.fr launched the previous year under Etalab, the cross-government mission led by Séverin Naudet inside the Premier Ministre's office. What it didn't yet have was a single licence everyone agreed on. Etalab had drafted the Licence Ouverte / Open Licence v1.0 explicitly modelled on the UK's Open Government Licence; the OpenStreetMap-derived Open Database Licence (ODbL) had partisans who argued for share-alike copyleft on the data layer; and Creative Commons advocates were pushing CC-BY for cultural-heritage data.

The fragmentation mattered because France's regional and local governments — Rennes, Paris, Nantes, Toulouse — had each begun publishing portals with their own licence choices, and downstream reusers building cross-département applications were facing licence-compatibility math the publishing institutions hadn't thought through. The French open-data community was particularly attentive to OpenStreetMap-style aggregation and to what would later become the Wikidata project, both of which forced share-alike questions to the surface earlier than in jurisdictions where most reuse was commercial.

The eventual settlement — Licence Ouverte for most government data, ODbL where mapping data was involved — emerged over the following two years and was effectively codified by the 2016 Loi pour une République numérique. But in late 2011 it was a genuinely contested space, with policy researchers at the Berkman Center, Open Knowledge, and the European Public Sector Information Platform watching to see how France would resolve it.
