Open Content License

The Open Content License is a copyleft license designed for distribution of open content material. This license is not compatible with the any other license in that it requires derivative works to be licensed under the Open Content License.

The Open Content License, dated July 14, 1998, predates the GNU Free Documentation License and other non-software public licenses, though discussions were held between David A. Wiley, creator of the Open Content License, and Richard Stallman, leader of the Free Software Foundation, who created the GNU General Public License for software and would create the GFDL.^[1] The license text is titled "Open Content License (OPL)" and the license is published at http://opencontent.org/opl.shtml. "OPL" stood for OpenContent Principles License.^[2] Another license released a year later, also by the Open Content Project is called the Open Publication License.
