The European Commission's Joinup platform has launched a new service: the so called "compatibility checker". It allows to check compatibility issues between Open Sources licences when you plan to use third party source code in your project. The objective of this functionality is to determine how far and on which licences a work using or combining data or software components licensed under two different licences can be distributed and (if it can be distributed) under which licence(s).

Following the Joinup Licensing Assistant that aims to help people to choose the right Open Source licence according to their needs, the compatibility checker is the latest addition to the extensive portfolio of solutions provided by the Joinup team to enable public administrations, businesses and citizens to share and reuse IT solutions and good practices, and facilitate communication and collaboration on IT projects across Europe.
