Thanks @Mat. I’ll connect you with the Hira architects for further discussion. Totally agree that we need to learn from others both in terms of what they have done and where they are heading.
One clarification on the managed data layer. While we expect the data to be federated (ie multiple trusted sources rather than one repository) the data governance and management will be a crown function either directly or via commercial relationships. In essence the outcome is the same, secure and trusted data.
