CC0

Summary

CC0 is a protocol that enables people to:

(a) ASSERT that a work has no copyright or neighboring rights restrictions attached to it.

OR

(b) WAIVE any rights associated with a work so it has no copyright or neighboring rights restrictions attached to it.

CC0 improves and extends the current CC public domain dedication. Key additions:

1. A protocol facilitating the conveyance of norms with a waiver or assertion statement.
2. Infrastructure for internationalizing the tools.
3. The assertion that content is in the public domain will be vouched for by users, so that there is a platform for reputation systems to develop. People will then be able to judge the reliability of content's copyright status based on who has done the certifying.

A beta version of the protocol, including the traditional components of the CC architecture -- legalcode, human-readable explanation, machine-readable metadata, and tools, has been launched for public discussion on January 15, 2008.
