CC BY 4.0 and CC BY-SA 4.0 added to our list of free licenses

by Joshua Gay Contributions Published on Feb 13, 2015 10:29 AM
The Creative Commons Attribution 4.0 International and Attribution-ShareAlike 4.0 International licenses are now on our list of free licenses for works of practical use besides software and documentation.

We have updated our list of Various Licenses and Comments about Them to include the Creative Commons Attribution 4.0 International license (CC BY 4.0) and the Creative Commons Attribution-ShareAlike 4.0 International license (CC BY-SA 4.0). Both of these licenses are free licenses for works of practical use besides software and documentation.

CC BY 4.0 is a noncopyleft license that is compatible with the GNU General Public License version 3.0 (GPLv3), meaning you can combine a CC BY 4.0 licensed work with a GPLv3 licensed work a larger work that is then released under the terms of GPLv3.

Creative Commons has begun a public discussion process for license compatibility evaluation in order to determine whether or not GPLv3 should be added to the list of CC BY-SA 4.0 Compatible Licenses. If GPLv3 is added to this list, then CC BY-SA 4.0 will be deemed one-way compatible with GPLv3, which means that a person can adapt a CC BY-SA 4.0 licensed work and release the adapted version under the terms of GPLv3.

Throughout the drafting process of both of these licenses, the FSF, with the help of the Software Freedom Law Center, provided feedback and suggestions to Creative Commons. We thank Creative Commons for giving us the opportunity to provide feedback and for incorporating many of our suggestions.

The FSF will continue to provide feedback throughout the current compatibility evaluation discussion process. We will also make updates to our list when have new information regarding compatibility between these CC licenses and other GNU licenses, such as GNU GPLv2 and the GNU Free Documentation License (GFDL).
