The CT Digital Archive (CTDA) is a digital preservation program that sustains and provides access to over 500,000 digital assets from the University of Connecticut and more than 30 other Connecticut institutions. It uses open-source technologies like Fedora Commons, Islandora, and Drupal to store, manage, and preserve digital files and records in a way that maintains their authenticity, reliability, and reusability over the long term. While participants retain ownership of their assets, the CTDA provides services and support for all aspects of digital preservation and management through policies, documentation, training, and technical infrastructure supported by the UConn Library.
