Abstract: The preservation of digital information for long periods of time is becoming feasible through the integration of archival storage technology from supercomputer centers, data grid technology from the computer science community, information models from the digital library community, and preservation models from the archivist''s community. The supercomputer centers provide the technology needed to store the immense amounts of digital data that are being created, while the digital library community provides the mechanisms to define the context needed to interpret the data. The coordination of these technologies with preservation and management policies defines the infrastructure for a collection-based persistent archive. This paper defines an approach for maintaining digital data for hundreds of years through development of an environment that supports migration of collections onto new software systems.
