The UK's largest collection of digital research data in the social sciences and humanities

Digital preservation

The UK Data Archive follows a policy of active preservation to ensure the authenticity, reliability and logical integrity of all resources entrusted to our care, while providing usable versions for research, teaching or learning, in perpetuity.

Our Preservation Policy is the codification of long-standing good archival practice at the Archive, and helps us meet legislative and accountability requirements and our user communities' expectations. It generally conforms to the OAIS Reference Model, with additions and alterations which are specific to the materials held in the Archive. Our policy lays down strict requirements for our digital preservation activities, together with how these requirements can best be achieved in relation to regulatory requirements, archival best practice, information security and available funds. The Archive's Preservation Policy is regularly revised, and based on open and available file formats, data migration and media refreshment.
