From the Article:
Currently in its start-up phase, DPN [Digital Preservation Network] is building a digital preservation backbone that connects five existing (or soon to exist, in the case of APTrust) preservation-oriented repositories: the Academic Preservation Trust (APTrust), Chronopolis, HathiTrust, Stanford Digital Repository (SDR), and the University of Texas Digital Repository (UTDR). Collectively, these five are known as the DPN nodes. The five nodes are located in different parts of the United States, and each brings with it a distinct architecture, hardware platform, and organizational/financial structure.
By linking the repositories and developing frameworks around audit, transport, and intellectual property management, DPN will make it possible to create “dark” copies (i.e., no end-user access) of the content across the various nodes while maintaining high confidence in the integrity and retrievability of that content.
DPN is designed to preserve digital information for the academy by establishing a network of heterogeneous, interoperable, and trustworthy digital repositories (DPN nodes) to provide preservation services under a coordinated and diverse technical, service, and legal framework. DPN nodes will operate in a secure manner to protect the integrity of the processes, transport, and content that DPN holds. As such, the creation of DPN provides multiple benefits to society, the academy, and DPN members.
