Open Data

The internet has changed the way we access, use, and share information. As a public sector body which makes laws for Wales and looks at the work of the Welsh Government, we produce a lot of information. This includes some datasets which are provided as open data. Making our work transparent and accountable are key priorities for the Welsh Parliament. We are opening up our content, because it is your content.

What data is currently available?

The following datasets are currently available for re-use under the Open Government Licence. For further information on licencing please read about Re-using public sector information.

In many places, we use XML (eXtensible Markup Language) to ensure that the information that we publish is open, transparent and not in a proprietary format. In computing terms, XML is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. XML was designed to make information sharing and data interpretation easier. Fundamentally, it helps different people, computers and systems understand each other on a digital platform. For further information on how to use XML please visit
