Which project can be hosted on Joinup? My program licensed under the EUPL uses components licensed under the GPL! Can I modify the EUPL? Are Joinup hosted projects “non-commercial” (program downloaded “for free”, free of licensing charges)? Does “Open source” require that source code of any modified versions be posted to the public? What to do if I discover a possible violation of the licence or of the Joinup principles? Is the use of the EUPL licence compulsory? Are there other Free/OSS licences? What about the EUPL? What is changed with the EUPL v1.2 published on 19 May 2017? Does the EUPL v1.2 applies to works licensed under the EUPL v1.1? Is the EUPL compatible with the GPL? Is the EUPL v1.2 copyleft weaker than before? Is the EUPL v1.2 convenient for licensing libraries? Report abusive content Share
