I think you need to ask: What is copyright? I was told that it's a right, a property created by creative work. It is attached to the output of that action (what we usually call "the work" here), but it is not that output: it's intangible itself. At http://www.eff.org/IP/?f=copyright_law.paper.txt there's a bit about "What is copyright?" which is along these lines. So, you can license your copyright, the result of any creative work you put into the software, with any compatible license, but the copyright to the original work remains under its original licence, no matter what you do. You still have to satisfy any conditions for accessing the copyright to that work, and people can take that bit and discard the stuff covered by your copyright if they want. See the GPL FAQ question about extracting a public domain part from a GPL-covered work. I think that covers your next two questions too. How clear you have to be about which parts have which copyrights attached depends on the licences, I think. Interpretations are often a bit dangerous to rely upon, so I won't answer the last two questions. I'm not a lawyer. Find better advice before doing anything which might even possibly be copyright infringement. ;-) -- MJR/slef My Opinion Only: see http://people.debian.org/~mjr/ Subscribed to this list.
