General information about the Joinup platform.
F/OSS licences are (too) numerous. Facing this proliferation, the Open-Source Initiative (OSI) is the main organisation maintaining a list of "approved licenses". The European Union Public Licence (EUPL) was created by the European Commission to comply with the European legal context: it is currently the sole licence which has official value in 22 linguistic versions. The EUPL was approved by OSI. The EUPL reduces the impact of license proliferation by providing a compatibility list, which includes the GPL.
