See https://en.wikipedia.org/wiki/Nicolas_Pettiaux & https://fr.wikipedia.org/wiki/Nicolas_Pettiaux (more precisions). I like to talk about Open in general, that I would rather like to replace by Libre or Free : source, access, education, data, publication, educationnal resources, science, representative committments ... Also OpenForum. be a discussion and meeting place to discuss "Open something", every 2nd Thursday of the months at 18h30 in Brussels, and MediVisu, a libre universal medical images viewer and management program and OpenEcho, a project to build a cheap portable echograph.
