The Open Content License is a share-alike public copyright license which can be applied to a work to make it open content. This license is not compatible with any other license in that it requires derivative works to be licensed under the Open Content License. With the exception of media and handling costs, it forbids charging for copies of a licensed work, but does not otherwise forbid commercial use.
The Open Content License, dated July 14, 1998, predates the GNU Free Documentation License (GFDL) 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. The license text is titled "OpenContent License (OPL)" and the license is published at http://opencontent.org/opl.shtml. "OPL" stood for OpenContent Principles and License. Another license released a year later, also by the Open Content Project is called the Open Publication License.
Famous quotes containing the words open, content and/or license:
“Observe decorum, and it will open a path to morality.”
—Mason Cooley (b. 1927)
“I could be content that we might procreate like trees, without conjunction, or that there were any way to perpetuate the world without this trivial and vulgar way of coition.”
—Thomas Browne (1605–1682)
“I go out of my way, but rather by license than carelessness.... It is the inattentive reader
who loses my subject, not I. Some word about it will always be found off in a corner, which will not fail to be sufficient, though it takes little room.”
—Michel de Montaigne (1533–1592)
