The Fedora Project, a global community leading the advancement of free, open software and content, today finalized the conversion of the licensing of its documentation and wiki to a Creative Commons Attribution-Share Alike 3.0 Unported License, also known as CC-BY-SA. This content was formerly licensed under the Open Publication License. Every six months, the Fedora Project produces a Linux distribution, as well as supporting documentation for each release. A project of this size has a large amount of process, boilerplate, and useful content beyond technical documentation. Moving to CC-BY-SA allows for wider reach of this documentation and content as more people understand that they can share and remix it in the same ways they can the software included in Fedora.

Today, the Docs team finalized the conversion of the licensing of our documentation and project content from the Open Publication License (OPL) to a Creative Commons Attribution-Share Alike 3.0 Unported License (CC-BY-SA). Docs originally reached a consensus to change the license in June 2009, and after answering questions raised by the community, the Docs team decided to go ahead with the transition. While OPL is a free and open documentation license, moving to a more widely known and adopted license and the one used by the likes of Wikipedia and GNOME Project helps us share our content more easily with the rest of the Free software community. We'd like to thank Tom 'spot' Callaway, Fedora's legal ninja, and Richard Fontana of Red Hat Legal for their help with the conversion. We look forward to continue working with the community and share our documentation freely.
