==== GPL-Compatible, Free Software Licenses ====

The GNU General Public License, or GNU GPL for short. http://www.fsf.org/licenses/gpl.html 
This is a free software license, and a copyleft license. We recommend it for most software packages.

The Clarified Artistic License http://www.statistica.unimib.it/utenti/dellavedova/software/artistic2.html 
This license is a free software license, compatible with the GPL. It is the minimal set of changes needed to correct the vagueness of the Original Artistic License.

==== Free Documentation Licenses ====
The GNU Free Documentation License http://www.fsf.org/copyleft/fdl.html 
This is a license intended for use on copylefted free documentation. We plan to adopt it for all GNU manuals.

The FreeBSD Documentation License http://www.FreeBSD.org/doc/en_US.ISO8859-1/books/handbook/ln15.html 
This is a permissive non-copyleft Free Documentation license that is compatible with the GNU FDL.

==== Licenses For Works Besides Software and Documentation ====
The Design Science License http://dsl.org/copyleft/dsl.txt 
This is a free and copyleft license meant for general data, not particularly for software.

Note, though, that the GNU GPL can be used for general data which is not software, as long as one can determine what the definition of "source code" refers to in the particular case. As it turns out, the DSL also requires that you determine what the "source code" is, using approximately the same definition that the GPL uses.
