CC0

Summary

CC0 is a protocol that enables people to WAIVE to the fullest extent possible under applicable copyright law all rights they have and associate with a work so it has no (or minimal) copyright or neighboring rights restrictions attached to it. To the extent the waiver is not legally effective in any jurisdiction, then the protocol takes the form of a nonexclusive worldwide license to exercise all copyright and neighboring legal rights in the work.

• A list of use cases is also available at CC0 Use Cases.

Overview

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

1. A protocol facilitating the conveyance of norms with a waiver statement.
2. "Universal" rather than U.S.-centric.

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 2008-01-15, a second beta on 2008-04-16, and a third beta on 2008-08-29.
