[nexa] CC Public Domain Mark

Improving Access to the Public Domain: the Public Domain Mark Today, Creative Commons announces <http://creativecommons.org/press-releases/entry/23755> the release of its Public Domain Mark <http://creativecommons.org/publicdomain/mark/1.0/>, a tool that enables works free of known copyright restrictions to be labeled in a way that allows them to be easily discovered over the Internet. The Public Domain Mark, to be used for marking works already free of copyright, complements Creative Commons' CC0 public domain dedication <http://creativecommons.org/about/cc0>, which enables authors to relinquish their rights prior to the expiration of copyright. http://creativecommons.org/weblog/entry/23830 Ciao, Paolo
