Chronopolis and MetaArchive: Preservation Cooperation

This paper will examine ongoing work between two major preservation systems, the Chronopolis Digital Preservation Program, [6] and the MetaArchive Cooperative. [13] In the past year, these two systems have begun work on bridging their technical underpinnings to create a more robust, reliable, longlived preservation community for their users. The main emphasis of this work is moving data between a LOCKSS-based system (MetaArchive) and an iRODSbased one (Chronopolis). This work also involves several other emerging preservation micro-service tools and practices, and the expertise of the University of North Texas (UNT) Digital Library [21] in deploying them. The final result of this work is intended to be of three-fold benefit: 1) directly improving the services offered by Chronopolis and MetaArchive to their constituents; 2) offering specific technical findings which will be of benefit to other systems using LOCKSS and iRODS; and 3) contributing to the larger preservation community through the examination of organizational best practices for preservation system interactions.
