Creative Commons has a big fat ZERO ready for anybody that would like to fully release their works to the public. The Zero license option under Creative Commons is as follows:
The person who associated a work with this document has dedicated this work to the Commons by waiving all of his or her rights to the work under copyright law and all related or neighboring legal rights he or she had in the work, to the extent allowable by law.
If you aren’t familiar with Creative Commons:
Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright licenses known as Creative Commons licenses. These licenses allow creators to communicate which rights they reserve, and which rights they waive for the benefit of recipients or other creators [wikipedia]
Under Creative Commons there are a few options to release your content:
There are 4 major permissions that are contained in Creative Commons licenses:
* Attribution (by) requires users to attribute a work’s original author. All Creative Commons licenses contain this option, but some now-deprecated licenses did not contain this component.
* Authors can either not restrict modification, or use Share-alike (sa), which is a copyleft requirement that requires that any derived works be licensed under the same license, or No derivatives (nd), which requires that the work not be modified..
* Non-commercial (nc) requires that the work not be used for commercial purposes.
As of the current versions, all Creative Commons licenses allow the “core right” to redistribute a work for non-commercial purposes without modification. The Non-commercial and No derivatives options will make a work non-free.
