Here are the proposals: For schematics symbols and for complete symbol libraries: "This work is licensed under the Creative Commons CC-BY-SA 4.0 License. To the extent that circuit schematics that use Licensed Material can be considered to be ‘Adapted Material’, then the copyright holder waives article 3.b of the license with respect to these schematics." For footprints and libraries of footprints: "This work is licensed under the Creative Commons CC-BY-SA 4.0 License. To the extent that circuit layout that uses Licensed Material can be considered to be ‘Adapted Material’, then the copyright holder waives article 3.b of the license with respect to this layout." This assumes we want a "weak copyleft" regime for libraries, i.e. we want modifications to symbols/footprints/libraries to be published under the same license, but we don't want to force people to publish their complete designs under CC-BY-SA just because they used the KiCad libraries. Then there is the issue of how to embed this information in symbols, symbol libraries, footprints and footprint libraries. I am not competent to comment on that. Cheers, Javier
