Hyperlinks to the Open Government Licence

It is helpful to tell search engines that the link to the Open Government Licence is to a licence. To do this in HTML, use the rel=”license” attribute.

This will enable automated systems to identify that the information is subject to a licence with particular terms and conditions which can be found by following the link.

Where possible, information providers should point to the permanent identifier for the Open Government Licence by embedding the following link:

<a href=”http://reference.data.gov.uk/id/open-government-licence” rel=”license”>Open Government Licence</a>

Alternatively, where information providers do not use the rel=”license” attribute, they can put in a simple hyperlink:

<a href=”http://www.nationalarchives.gov.uk/doc/open-government-licence/”>Open Government Licence</a>

Specifying attribution statements

The OGL requires that users attribute the information provider and source of the information they use. Where you require a specific form of attribution, you should include a statement with the above copyright notices, such as the following example:

When you use this information under the Open Government Licence, you should include the following attribution: [Insert name of information resource, information provider and/or rights owner, date of publication], licensed under the Open Government Licence [insert link].
