CC0 use for data - Creative Commons

CC0 (read “CC Zero”) is a universal public domain dedication that may be used by anyone wishing to permanently surrender the copyright and database rights (where they exist) they may have in a work, thereby placing it as nearly as possible into the public domain. CC0 is a legal tool that improves on the “dedication” function of our earlier, U.S.-centric public domain dedication and certification.
