It was developed and is maintained by The National Archives. It is compatible with the Creative Commons Attribution (CC-BY) licence.
History
Since 2001, some works of the UK government had been made available under the Click-Use Licence. This was replaced by the first version of the OGL when it was released on 30 September 2010. The OGL was developed by The National Archives.
The OGL was developed as part of the UK Government Licensing Framework, which also includes a non-commercial Government licence that restricts the commercial use of licensed content, as well as a charged licence for situations where charging for the re-use of content is deemed appropriate.
The first version was designed to work in parallel with other licences such as those released by Creative Commons, mirroring the Creative Commons Attribution (CC-BY) licence and the Open Data Commons Attribution Licence.
