Wikimedia Foundation Announces Licensing Change

May 29, 2009


The Wikimedia Foundation Board of Trustees passed a resolution that will bring about changes to the way the content of the Wikimedia Foundation projects, including Wikipedia, will be licensed. This resolution follows a vote among the international Wikimedia community. The decision will result in all of the Wikimedia Foundation's projects moving from the GNU Free Documentation License (GFDL) to the Creative Commons Attribution/Share-Alike License (CC-BY-SA) as their primary content license. The GFDL, which has served Wikipedia since its inception, will continue to be supported where possible. The licensing change means that all Wikimedia project content will be more interoperable with existing CC-BY-SA content. With the dual-license system in place, content can be further re-used under either the GFDL or the CC-BY-SA license, but the GFDL will be dropped from content objects where this is necessary to support remixing it with existing CC-BY-SA content.
