*"Géocommun"* `[ʒeokɔmɛ̃]` : is it the latest buzzword in France or a large movement towards more openness in the geospatial realm ? The French National Geographical Institute (IGNF) recently started communicating its vision towards the development of Geo-commons. This sounds like a strategical change in the way the institute apprehends geo-data and geo-software production. In this presentation, we first try to give a definition of what a "geocommon" is. Then we review the initiatives currently being deployed by various actors in France to transform this word into a reality. We study the roots of these actions and their links to opendata, opensource and opengov movements. We also try to provide a mindmap of involved actors, and how they interact together : administrations, data-oriented communities or software-oriented communities. Then we anticipate the impact on free and opensource software for geomatics, and how it could affect technologies and communities in this area.
