Joint initiative boosts academic preservation options
Winchester, MA The DuraSpace and Chronopolis teams have partnered to offer an end-to-end solution for long-term access and preservation services for academic and scholarly data. The offering is part of a larger project called the Digital Preservation Network (DPN). Users will be able to ingest and manage their content in DuraCloud for easy-to-use offsite cloud backup and archiving, and also push a copy of their content into the Digital Preservation Network for long-term preservation.
The DuraCloud software enables users to upload their content and create a snapshot of that content at any point by simply clicking a button in the user interface. The snapshot created in DuraCloud is transferred to Chronopolis, where checksums for each content item are verified, a manifest is generated, and the snapshot is moved into Chronopolis storage. Chronopolis is a preservation node in the DPN network. Once content is in Chronopolis, copies are replicated to a minimum of two other nodes in the network and monitored for life.
As an added benefit, a listing of the content that comprises each snapshot is accessible in the DuraCloud interface. Users can retrieve content from Chronopolis by requesting a stored snapshot in DuraCloud. Content can then be transferred out of Chronopolis storage and restored to the DuraCloud content staging area in DuraCloud. DuraCloud also provides the option of keeping snapshotted content to Chronopolis available for immediate download using another DuraCloud storage provider.
The Chronopolis digital preservation network (https://chronopolis.sdsc.edu) has the capacity to preserve hundreds of terabytes of digital data-data of any type or size, with minimal requirements on the data provider. Chronopolis comprises several partner organizations that provide a wide range of services. The partners include the UC San Diego Library, the San Diego Supercomputer Center (SDSC) at UC San Diego, National Center for Atmospheric Research (NCAR), and the University of Maryland Institute for Advanced Computer Studies (UMIACS).
The project leverages high-speed networks, mass-scale storage capabilities, and the expertise of the partners in order to provide a geographically distributed, heterogeneous, and highly redundant archive system. Features of the project include: three geographically distributed copies of the data; curatorial audit reporting; and the development of best practices for data packaging and sharing. A Center for Research Libraries (CRL) audit has certified Chronopolis as a "trustworthy digital repository" that meets accepted best practices in the management of digital repositories. The TRAC criteria includes organizational infrastructure, digital object management, technologies, technical infrastructure, and security. These criteria represent best current practices and thinking about the organizational and technological needs of trustworthy digital repositories.
