Distributed digital preservation networks have been growing in popularity among institutions that wish to collect and preserve materials of high importance to specific communities. This project briefing will include discussion of a multi-institutional project to develop an open-source platform for distributed multi-institutional asymmetric replication of archival content. The goal of the project is to support policy-driven replication of large collections of research data, where the partners in the replication network differ significantly in the size of their collections and in the resource commitments they are able to contribute to the network. We have built a prototype system by using a core of Private LOCKSS Networks (PLN) technology, developing a schema to encapsulate inter-archival replication commitments, building an automated schema-driven service that audits PLN’s, and by adapting Open Archives Initiative (OAI) harvesting clients to harvest data collections from the Dataverse Network (DVN) and other repositories using the Data Documentation Initiative (DDI) schema. This work is conducted by Data-PASS, a partnership of five major archives, and it is supported by the Library of Congress (National Digital Information Infrastructure and Preservation) NDIIPP program.
