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).
In other words, how far the planned outbound licensing terms are compliant with the inbound licensing terms of the used source code.
Select ONE inbound licence (covering the third party source code that you plan to use in your project), and ONE outbound licence (already covering your main project source code and/or planned for the distribution of your project).
