Research and Development Plan and Schedule for the Research Project on Application of Distributed Object Computation Testbed Technologies to Archival Preservation and Access Requirements

摘要

The San Diego Supercomputer Center is developing prototypes for collection-based persistent archive infrastructure in collaboration with the National Archives and Records Administration. The prior work under the fiscal year 1999 NARA extension to the DOCT project demonstrated the technology needed to assemble a collection-based persistent archive. An initial prototype defined a migratable information architecture and a scalable data archive. The key concept developed in the prototype was the provision of separate information descriptions for the digital object structure, collection organization, and presentation interface. This allowed the: Separation of data archiving from data accessioning; Separation of management of the collection organization from storage of digital objects; Separation of presentation and querying of the collection from collection management. The distribution of functionality into separate components was made possible through the use of a data handling system (the San Diego Supercomputer Center Storage Resource Broker) that connected data flows across all of the systems.
