Since April 2005 Creative Commons has been working on versioning up its core licensing suite. The Creative Commons licenses (For an overview of the licenses see: [1]) serve as an important vehicle by which many millions of creators clearly signal to the world that they are happy for members of the public to engage in some of the exciting new uses of content that are made possible by digital technologies. Using a CC license an artist can for example invite the public to share their work or mash it up (on certain conditions).
