The Digital Preservation Network (DPN) will officially close February 28, 2019

The Digital Preservation Network (DPN) will officially close February 28, 2019.  Over the past few months, we have been in communication (either via e-mail or phone/video call) to discuss the disposition of the content deposited into DPN.  Many institutions have transitioned to establishing ongoing relationships with former DPN Nodes. Other institutions indicated that they are examining options but did not need copies of their content returned to them. Only one institution needed a copy of their content returned to them, and that has been done.


DPN staff are in the process of writing a final report which all DPN members will receive. This report will present as clear a picture as possible of the project and will include a description of what was accomplished, what was not accomplished, and what we learned from this work. Aspects of our work (such as the DPN Bag specification, the workflow curriculum, etc.) that was developed over the last six years will live on and will be accessible to those interested in pursuing work in long-term digital preservation. The DPN website will be preserved in the Wayback Machine, the archived documents and presentations will be deposited in Deep Blue at the University of Michigan and the curriculum and software in the Open Science Framework https://osf.io.


Thank you for your support of the work of DPN over the past six years. It has been a privilege working with you in advancing the thinking around long-term digital preservation.



Digital Preservation Network is no more - blog by David Rosenthal

The point of DPN was to use organizational and technological diversity to mitigate monoculture risk. Unfortunately, as Brian Arthur's 1994 Increasing Returns and Path Dependence in the Economy described, technology markets have increasing returns to scale. Thus as services scale up diversity becomes an increasingly expensive luxury, and monoculture risk increases. Fortunately, the winner then acquires too-big-to-fail robustness (see Amazon).


Why Is the Digital Preservation Network Disbanding?

Information Update

Dear colleagues,

Yesterday, we announced to members and depositors of the Digital Preservation Network that we are winding down and sunsetting the organization.  It was a difficult decision for the DPN board and staff, but after examining the options, it was determined to be the best path to ensure an orderly transition for depositors. Since the beginning of DPN over five years ago, the organization has operated in an environment of rapid change.  We--the organization and the community--have learned many valuable lessons. The DPN board and staff expect these lessons will contribute to future efforts to preserve valuable digital content and will also inform continuing work to sustain community-based organizations.

The following may serve to provide context for the decision to wind-down DPN.

The model of preservation storage provision under which DPN currently operates is not a match for a sufficient number of institutions in today’s environment to be economically sustainable. DPN’s financial model assumed a critical mass of member institutions making large preservation storage deposits. Both the membership numbers and the scale of storage deposits have fallen below the critical mass needed.

  • The general environment for preservation storage has changed since DPN was founded, and the current DPN model is not perceived to be a sufficiently cost-efficient complement to other campus arrangements.  For example, institutions that already have secure preservation storage in one or more cloud-based sites may not elect to pay for a service that maintains three additional copies in dedicated locations.

  • The succession agreements and 20-year term conditions of DPN do not match the planning cycles and ownership expectations at many institutions.

  • Many institutions do not have the digital preservation workflows necessary for routine deposit to an external preservation repository.

DPN’s work has been an important, constructive learning process for the digital preservation community and will lead to new models of collaborative digital storage services.

  • The investment in research and development work with the Nodes (AP Trust, Chronopolis, HathiTrust, and the Texas Digital Library) benefitted all in areas such as replication, ingest, and registry and metadata management.  This activity has proven its value and will continue and expand in other services and the work of the Nodes.

  • With the benefit of DPN research and experience, future models should be able to optimize centralized coordination services and reduce costs.

  • The investigation into succession planning and long-term commitment illuminated what is actually feasible in the institutional context.  While research universities and cultural heritage institutions are innately long-running, they operate on that implicitly rather than by making explicit long-term plans.  This needs to be incorporated into digital preservation planning.

  • Services requested by (and provided to) DPN members have identified a significant need for operational development in the areas of selection for and workflow management of digital preservation. It is important that the community keep that work going.

  • Many institutions have better understood their own workflows and requirements by exploring the DPN model.

Although DPN, in its post-research and development phase, was not able to sustain sufficient scale to establish its desired 20 year “endowed” model, all digital data are secure and will, as needed, be returned to depositors.  DPN is working with each depositor to determine if content needs to be returned and is developing a timetable and process for any necessary returns. Most depositors have their own preservation copies of content in addition to the DPN copies and are not expected to seek a return. Three of the DPN nodes (AP Trust, Chronopolis, and TDL) are positioned to provide digital preservation services to current DPN depositors.  DPN will assist in that transition.

Finally, we would like to thank the community, especially the DPN members and the Node partners for the support of DPN and the progress we have made in digital preservation.



Community Announcement - DPN Sunset

After careful analysis of the Digital Preservation Network’s membership, operating model, and finances, the Board of Trustees of DPN passed a resolution to affect an orderly wind-down of DPN.  The DPN Board carefully considered potential changes to DPN’s current preservation and membership models and determined that it is not feasible to design and implement changes that would ensure sustainability.

The Digital Preservation Network has provided innovative digital preservation services and leadership to the cultural heritage community for the past six years.  At its largest, DPN had 62 members and deposits from 27 institutions. However, membership has fallen to 31, a number insufficient to maintain the organization. The landscape of digital preservation services has changed considerably in the past six years, as have the community’s preservation needs.

Our highest priority is to affect an orderly sunset for the organization’s operations and for the disposition of its deposits.

Recently, DPN stopped accepting new deposits. As DPN implements sunset of the organization and services, each depositing member will work with DPN staff to plan for the disposition of their content. DPN staff will also assist with referral and data movement workflows.

We appreciate the community’s support of DPN.  We are grateful to the many knowledgeable and dedicated staff at member and node organizations who contributed to advancing the field of digital preservation through our collective work. The DPN board, staff, and nodes are committed to a graceful shutdown and to working with our members to assure that deposited content is transitioned successfully.  We are also committed to the larger community in discussing lessons learned.

It is clear that there are numerous unforeseen challenges with our community-based organizations that need to be addressed.  A number of organizations formed by our community are facing sustainability challenges, despite initial momentum. The DPN board and staff hope that the community enters into conversations that may help other organizations in the challenge of sustainability.
