From Fedora Project Wiki
This stuff is totally a work in progress and you should help make it better. Thanks!

The Fedora Project, a global community leading the advancement of free, open software and content, today finalized the conversion of its documentation and wiki to the Creative Commons Attribution-Share Alike 3.0 United States License, also known as the CC BY-SA. This content was changed from the Open Publication License (OPL). Every six months, the Fedora Project produces a Linux distribution, as well as supporting documentation for each release. Moving to the CC BY-SA allows for wider reach of this documentation as more people understand that they can share it in the same ways they can share the software included in Fedora.

Today, the Docs team finalized the conversion of our documentation from the Open Publication License (OPL) to the Creative Commons Attribution-Share Alike 3.0 United States License (CC BY-SA). Docs originally reached a consensus to change the license in June 2009, and after answering any questions raised by the community, the Docs team decided to go ahead with the transition. 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 hope it brings greater interoperability with free documentation.
