Stakeholder Engagement

The set of data catalogue requirements was created through engagement with data analysts and business users in the UK Power Networks Distributed Network Operator (DNO) and System Operator. This was shared with other DNOs who have similar tools or were in the process of procurement to validate the list, resulting in additional requirements being added. Through the data shared on the CLEO and Open Data projects, we have added additional metadata to our standard as requested by data users, including data update frequency and data themes.
