Creative Commons Unveils Machine-Readable Copyright Licenses

Creative Commons, a nonprofit dedicated to promoting the creative reuse of intellectual works, launched its first product today: its machine-readable copyright licenses, available free of charge from creativecommons.org. The licenses allow copyright holders to easily inform others that their works are free for copying and other uses under specific conditions. These self-help tools offer new ways to distribute creative works on generous terms - from copyright to the public domain - and are available free of charge.

"Many copyright owners are willing to share their works with others without charging a fee," said Stanford Law Professor and Creative Commons Chairman Lawrence Lessig. "Public exposure benefits both the copyright owners and the users and creators who want access to existing works. But how can a creator describe the terms on which he or she is sharing a creative work? That's where the Creative Commons licenses come in. Our licenses promote the innovative reuse of all types of intellectual works, unlocking the potential of sharing and transforming others' work."

Creative Commons licenses help people express a preference for sharing their work - on their own terms. Copyright holders who decide to waive some of their rights but retain others can choose a license that declares "Some Rights Reserved" by expressing whether they require attribution or allow commercial usage or modifications to their work. Additionally copyright holders may select to waive all their rights and declare "No Rights Reserved" by dedicating their work to the public domain. After the copyright holder chooses their license or public domain dedication, it is expressed in three formats to easily notify others of the license terms:

1. Commons Deed. A simple, plain-language summary of the license, with corresponding icons.

2. Legal Code. The fine print needed to fine-tune your copyrights.

3. Digital Code. A machine-readable translation of the license that helps search engines and other applications identify your work by its terms of use.

"Our model was inspired in large part by the open-source and free software movements. The beauty of their approach is that they're based on copyright owners' consent - independent of any legislative action - and motivated out of a wonderful mixture of self-interest and community spirit," explained Creative Commons Executive Director Glenn Otis Brown. "One of the great lessons of these software movements is that the choice between self-interest and community is a false choice. If you're clever about how you leverage your rights, you can cash in on openness. Sharing, done properly, is both smart and right."

Cyberlaw and intellectual property experts James Boyle, Michael Carroll, Molly Shaffer Van Houweling, and Lawrence Lessig, MIT computer science professor Hal Abelson, lawyer-turned-documentary filmmaker-turned-cyberlaw expert Eric Saltzman, and public domain Web publisher Eric Eldred founded Creative Commons in 2001. Fellows and students at the Berkman Center for Internet & Society at Harvard Law School helped get the project off the ground. A non-profit corporation, Creative Commons is based at and receives generous support from Stanford Law School and the school's Center for Internet and Society.
