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:
“Parents’ accepting attitudes can help children learn to be open and tolerant. Parents can explain unfamiliar behavior or physical handicaps and show children that the appropriate response to differences should be interest rather than revulsion.”
—Dian G. Smith (20th century)
“Now they express
All that’s content to wear a worn-out coat,
All actions done in patient hopelessness,
All that ignores the silences of death,
Thinking no further than the hand can hold,
All that grows old,
Yet works on uselessly with shortened breath.”
—Philip Larkin (1922–1986)
“It would much conduce to the public benefit, if, instead of discouraging free-thinking, there was erected in the midst of this free country a dianoetic academy, or seminary for free-thinkers, provided with retired chambers, and galleries, and shady walks and groves, where, after seven years spent in silence and meditation, a man might commence a genuine free-thinker, and from that time forward, have license to think what he pleased, and a badge to distinguish him from counterfeits.”
—George Berkeley (1685–1753)
