The OGL is a licence developed by the National Archives as a tool to enable information providers in the public sector to license the use and re-use of their information under a common open licence. So this will apply to much of the documentation published by government departments and other public sector bodies. For example, the GOV.UK website states that all content, which is Crown copyright, is made available under the Open Government Licence v3.0, except where otherwise stated. The OGL allows users to copy, publish, distribute, transmit and adapt the information, including for commercial purposes. It is important to read the full licence to ensure that you are abiding by all the required terms and conditions, particularly in relation to the correct attribution of material. There are also some categories of content that are exempt from coverage of the OGL, including personal data, logos and crests, identity documents, and other intellectual property rights such as patents and trade marks.
