The UK's largest digital collection of social sciences and population research data

Data preservation and trust

We ensure the authenticity, reliability and logical integrity of all our data, so we can provide usable versions for research, teaching or learning.

Our preservation policy is based on years of good practice and helps us meet legislative and accountability requirements and our users' expectations. We align our activities with the OAIS Reference Model, with additions and alterations which are specific to the materials we hold.

Our policy is regularly revised, and based on open and available file formats, data migration and media refreshment. It lays down strict requirements for our digital preservation activities, together with how these can best be achieved in relation to regulatory requirements, archival best practice, information security and available resources.

We are a Trusted Digital Repository and a member of the Digital Preservation Coalition. We hold and make accessible authentic and reliable versions of data through long-term preservation and provide continuous access. We also offer reliable information on how the reproducibility of research results based on our data might be affected by changes to the data.
