Open source license
<legal> Any document that attempts to specify open source
usage and distribution of software.
These licenses are usually drafted by experts and are likely to be more legally sound than one a programmer could write.
However, loopholes do exist.
Here is a non-exhaustive list of open source licenses:
1. Public Domain
- No license.
License - An early open source license
3. General Public License
(GPL) - The copyleft
license of the Free Software Foundation
Used for GNU
software and much of Linux
4. Artistic License (http://www.my-opensource.org/Artistic.txt) Less restrictive than the GPL, permitted by Perl
in addition to the GPL.
5. Mozilla Public Licenses (http://www.mozilla.org/MPL/). (MPL, MozPL) and Netscape Public License (NPL).
