The DPN Vision

DPN will ensure that the complete scholarly record is preserved for future generations. It will be the long-term preservation solution shared collectively across the academy that protect local and consortia preservation efforts against all types of catastrophic failure. The supporting ecosystem enables higher education to own, maintain and control the scholarly record throughout time. While commercial entities may partner with us to contribute to this effort at different points in time depending on priorities and business models, final control must reside with the academy.


In the DPN ecosystem, local repositories become contributing nodes, which ingest new forms of scholarship and new collections. DPN creates several federated, replicating nodes, which are digital repositories for the contributing nodes with a specific focus on long-term preservation. The replicating nodes contain redundant, dark copies of all deposits that can be brightened in cases of catastrophic loss. The diversity of the DPN nodes mitigates the risk of a single point of failure. Objects and metadata are replicated across nodes that embody organizational, technical, physical, and political diversity. A single point of failure cannot jeopardize centuries of scholarship.

The DPN Team

The individuals and organizations that are leading DPN are the most knowledgeable in the preservation community. The team is incredibly deep and most have been working on preservation challenges for many years. We invite you to meet our veteran team members highlighted below.

Current Work

DPN is actively progressing three important projects that will create a working proof of concept of the core components. The DPN node sub-group is defining the technical architecture for the replicating nodes. The governance sub-group is defining a governance and sustainability model. The data partnerships sub-group is completing an environmental scan of research data preservation.

Business Model Working Group Show Members

A viable business model must be established which is practical, sustainable, scalable and able to support DPNs preservation mission to indefinitely preserve the academic record. The Business Model Working Group is charged to identify the appropriate economic model to fund the initial development and launch of DPN and be one that can scale with demand. Initial discussions have been divided into three sub-groups: Policy, Expense, and Revenue.

Succession Rights Working Group Show Members

This working group was appointed to advance DPNs interest in securing succession rights for the data deposited within the system. The work has focused on identifying best practices among the organizations focused on data preservation, and on developing templates that can be used to define the license agreement between a data depositor and a repository and between the repository and DPN.
