Compatibility of Liberal Licenses
Compatibility with each other and with other licenses
Compatibility with each other
If you are going to combine a material which is licensed under a Liberal License with other material licensed under another Liberal License to a larger work, then you can enjoy a perfect compatibility, because all Liberal Licenses are compatible with each other. Thus, for a larger work which consists of materials under Liberal Licenses only you can find always at least one Liberal License that you can use to license that larger work. Be aware that the compatibility is strictly unidirectional in order to prevent any loop hole in certain protection features provided by particular Liberal Licenses. For instance a larger work that contains material licensed under a LL-AS and a LL-PS can be licensed as a whole under a LL-PS, but not under a LL-AS, because otherwise a licensee could misuse that compatibility to annul the protection given by the LL-PS and to gain rights the licensor is not willing to grant.
Furthermore, all Liberal Licenses are compatible with any higher version (future version) of the respective license. And also when a Liberal License admits another Liberal License as a umbrella license for a larger work, then it always admits any higher version of that admitted license as well.
Please find examples of license combinations in larger works in the table below (the green cells show the possible Liberal Licenses for the respective combination).
