Five years after the launch of the first Creative Commons licensing suite, Creative Commons and Science Commons invite the community to expand the framework through new tools, or protocols: CC+ to signal external transactions, CC0 to waive rights, and Science Commons Open Data Protocol. Are user communities invited to appropriate, extend and customize the licenses, creating a participatory code? Should musicians self-organize and create their own structures complementary to Creative Commons licensing to collect remuneration, or can collective society schemes accommodate a possible paradigm change from public performance vs private use to commercial vs non commercial rights? How can scientific communities and government develop models to open scientific data? Is online distribution for music, and the semantic web for science, shifting legal paradigms toward “commercial rights reversed” and “no rights reserved”?
