Using software licenses for other content
Some free software licenses, including the GNU General Public License (GPL) and European Union Public Licence, can also be used to license content other than software. However, the FSF has recommended against using the GPL for educational works.
- CC0 is technically not a license, although it is often called one. The legal code of CC0 does contain a "Public License Fallback" clause, which will act as a free content license when a jurisdiction does not recognizes the 'waiving your rights' part for some reason. See also the CC0 FAQ.
