The Digital Preservation Network (DPN) is a nationwide initiative to create a preservation backbone for digital information of interest to the academy. DPN comprises a handful of large-scale preservation repositories, which together form a heterogeneous network of secure, trustworthy digital archives, each operated under diverse geographical, organizational, financial, and technical regimes. Robust (bit) auditing and repair functions ensure the integrity and security of content over time. Intellectual property agreements among depositors, repositories and the university members of the Network ensure succession of rights to use content in the event of the dissolution of the original depositor or archive. Since late 2012, a technical team from the five initial nodes has been working on an initial implementation of the network. This presentation will present that group’s work, which includes basic design principles, functional requirements and system specifications; the Network’s high level architecture and protocols for content replication and auditing; and framing of detailed service and policy questions that will drive the Network’s overall design and operation. DPN members and digital preservation experts are especially encouraged to attend and participate in this interactive session.










  1. […] Work from DPN’s Technological Team work was featured at the CNI Spring Member Meeting in San Antonio, Texas in early April. The presentation featured a review of DPN’s design and specification, and in depth review of the messaging architecture. A full description of the presentation as well as a download of the PowerPoint can be found here.
