It's a somewhat complicated question: If the extension isn't a derived work of the GNOME Shell code, then it's fine to distribute the extension code under whatever license you want - BSD, proprietary, whatever. Because it's not a derived work of GNOME Shell, the license of GNOME Shell can't matter. Now, the combination of GNOME Shell and the extension wouldn't be distributable. So as a _policy_ thing (not a legal thing), we we probably in any case want to require all extensions on extensions.gnome.org to be at least GPL compatible - to be under GPL, LGPL, BSD, MIT, etc. But are extensions derived works of the GNOME Shell code? If you copy code from GNOME Shell, obviously that makes your code a derived work. If you don't copy any code - if all the code is written from scratch, then there is still an argument that since you had to look at the GNOME Shell code to write your extension, you had to test your code with the shell, etc, it might still be a derived work. (This is something that has been discussed at great length with respect to the kernel modules; I don't think there's a definitive answer.) To me, the simplest thing is that we require authors to agree to distribute their code under the GPL v2 or later when they upload an extension to extensions.gnome.org, and that's the license we use when distributing extensions. If an extension author wants declare in a README file or code comments that their extension code is also available under more permissive terms, that's their call, and it's not up to us to check that assertion or prevent them from making it. - Owen _______________________________________________ gnome-shell-list mailing list gnome-shell-list@gnome.org http://mail.gnome.org/mailman/listinfo/gnome-shell-list
