Software constitutes an important share of PP developments. Open Source Software (OSS) licences are generally the preferred conditions for users and developers to access the PP community’s codes because these licences offer a suitable environment for the development of large and complex software with appropriate reliability and robustness. However, in terms of commercial exploitation, the OSS scheme suffers from several critical aspects. In order to analyse the situation, the TT Network organises a workshop at CERN on October 21 addressing issues related to the use of open source software for academic and commercial purposes on the basis of practical cases presented by the Nodes. Industry representatives are invited to present their experience in using OSS, engineers from important software institutions to present their experience in TT with OSS and legal experts to address the different OSS licences as well as the mechanisms for doing business with this software. Conclusions and key lessons learned will be the subject of a report to be circulated to the KTT Offices of the PP community.
