GFDL is the GNU Free Documentation License, the copyright under which Wikipedia formerly published.
|As of July 15, 2009,[update] Wikipedia has moved to a dual-licensing system that supersedes the previous GFDL-only (GNU Free Documentation License–only) licensing. In short, this means that text licensed under the GFDL-only licensing can no longer be imported into Wikipedia, retroactive to November 1, 2008. Additionally, Wikipedia text might or might not now be exportable under the GFDL, depending on whether or not any content was added and not removed since July 15, 2009. See Wikipedia:Licensing update for further information.|
