Digital curation and data publishing

Our approach to data preparation and curation, and the standards we use, mean that data can be accessed now and in the future.

Our organisation is a Trusted Digital Repository with a mission to provide reliable, long-term access to managed digital resources now and in the future. Information security is at the heart of the UK Data Archive's work. We are certified to ISO 27001, the highest international security standard, which informs our work every day and helps us establish and maintain trust.

We help to define, meet, and support the adoption of, appropriate and universal standards in this area, and have made many of our own policies and procedures available. Find out more:
