About the Project
The Data-PASS partners have built a prototype syndicated storage platform for redundant backup of digital holdings. This prototype system is built around a core of Private LOCKSS Networks (PLN); a schema to encapsulate inter-archival replication commitments; an automated schema-driven service that audits PLN's; and Open Archives (OAI-PMH) clients to harvest data collections from the Dataverse Network (DVN) and other repositories using the Data Documentation Initiative (DDI) schema.
