Current draft
Tentatively, the following licenses are known to meet the criteria set out by the definition:
- Creative Commons Attribution License (not free for Debian)
- Creative Commons Attribution/Share-Alike License (not free for Debian)
- GNU Free Documentation License when no invariant sections are specified (this is important)
- Free Art License (not free for Debian)
- Against DRM 2.0
- All free software licenses. While many of them are specific to software, some are worded so as to apply to all kinds of digital works. For example, the GNU GPL is often applied to non-software works (such as computer graphics, game scenarios...).
In addition, works in the public domain are also free content as per the definition.
To be verified:
Controversial:
- IANG license - seeks to enforce lots of things that are outside of the copyright realm (like organization scheme, right of developers to have a voice in the development process, etc.)
