About SafeArchive

SafeArchive is a solution for archival storage and replication management. Designed by the Data-PASS partners, it is a storage platform for policy-driven, distributed replication of digital holdings. The current version of SafeArchive is a self-contained system that can be installed, used and maintained by institutional staff without technical expertise. The set of open source tools can easily be used by libraries, museums and archives that wish to replicate their own content.

SafeArchive allows collaborating institutions to monitor peer-to-peer replication. Participating institutions expose content on their web sites, or  through their institutional repositories such as the Dataverse Network (DVN) digital library system or DSpace. Replication harvesters, such as LOCKSS nodes, collect this content through web crawling or the  OAI-PMH protocol.  The SafeArchive system monitors and manages these replicas.

SafeArchive is policy-driven. Institutions participating in the network will then choose which of their own and which of the other partners' content to replicate by creating policies (or rules), which will be formalized in a machine-readable schema. Since partners vary in size and technology, the policy commitments will be able to scale to the participants' resources.

The latest SafeArchive version, in development, automatic provisioning. When new collections are added to the preservation network, the system will provide a way to automatically identify collaborating peers with the required resources and initiates regular harvesting by those peers. Previous versions of the replicated content will be maintained, as well.

Although the SafeArchive system was tested with a core LOCKSS network, the team has plans to test the system on other types of networks.

The SafeArchive project is a collaborative effort of the Data-PASS Partners:  The Inter-university Consortium for Political and Social Research, University of Michigan; the Roper Center for Public Opinion Research, University of Connecticut; the Howard W. Odum Institute for Research in Social Science, University of North Carolina at Chapel Hill; U.S. National Archives & Records Administration (NARA); and the Institute of Quantitative Social Science, Harvard University.  It is managed through the Institute of Quantitative Social Science and works in collaboration with the LOCKSS project at Stanford University.

The project is sponsored by the Institute of Museum and Library Services, under award #LG-05-09-0041-09. The Institute of Museum and Library Services is the primary source of federal support for the nation’s 123,000 libraries and 17,500 museums. The Institute's mission is to create strong libraries and museums that connect people to information and ideas.

SafeArchive also received funding from Library of Congress National Digital Information Infrastructure and Preservation Program (NDIIPP).
