Licensing Resources

GPL

Richard Stallman (Free Software Foundation) describes "copyleft" as the opposite of copyright. Copyright protects a creator's right to control copies and changes to a work, whereas copyleft (also known as the GPL license) protects a user's right to copy and change a work.

It is a license that allows free re-use and modification of creative work so long as the derivative work remains available on the same terms.

(See Free Software Foundation and the CopyLeft page on the GNU.org site)

Creative Commons Licensing

These licenses all grant certain baseline rights, such as the right to distribute the copyrighted work on file sharing networks.

The rest of the license depends on the version, and is comprised of a selection of four conditions:

  • Attribution (by): Permit others to copy, distribute, display, and perform the work and derivative works based upon it only if they give you credit.
  • Noncommercial or NonCommercial (nc): Permit others to copy, distribute, display, and perform the work and derivative works based upon it only for noncommercial purposes.
  • No Derivative Works or NoDerivs (nd): Permit others to copy, distribute, display and perform only verbatim copies of the work, not derivative works based upon it.
  • ShareAlike (sa): Permit others to distribute derivative works only under a license identical to the license that governs your work. (See also copyleft.)
