They are written by a lawyer, and I don't see how they could be misinterpreted. Incidentally, geda does the same, except taking GPL as a basis instead of CC-BY-SA: http://wiki.geda-project.org/geda:license Again, for me the question is: do we want to *explicitly* allow people to take components of a library, improve them and not share the improvements back? If yes, CC0. If not, CC-BY-SA with the proposed paragraphs to clarify that the license provisions do not extend to the whole schematics, layout or circuit model. Cheers, Javier
