Creative commons: nova generació de llicències 4.0
The 4.0 licenses are extremely well-suited for use by governments and publishers of public sector information and other data, especially for those in the European Union. This is due to the expansion in license scope, which now covers sui generis database rights that exist there and in a handful of other countries.
[...] new features are improved readability and organization, common-sense attribution, and a new mechanism that allows those who violate the license inadvertently to regain their rights automatically if the violation is corrected in a timely manner.
[...] CC marks the most permissive of its licenses as “Approved for Free Cultural Works.” When you apply these licenses to material you create, it meets the Freedom Defined definition of a “Free Cultural Work.” Free cultural works are the ones that can be most readily used, shared, and remixed by others, and go furthest toward creating a commons of freely reusable materials.
