Preservation, metadata and the OAIS
information model: A metadata framework to support the preservation of digital objects.
(3.) The OAIS
reference model was developed b v the Consultative Committee for Space Data Systems (http://ssdoo.gsfc.nasa.gov/nost/wwwclassic/documents/pdf/ CCSDS-650.0-B-1.pdf); it defines the components of a digital archive and the functions each component supports, as well as an abstract data mad metadata model for digital content.
While created for space data, OAIS
is widely accepted as being applicable to a broad range of data types.
By the time NEDLIB had created the first draft of a generic model for a depository for electronic publications, the OAIS
Reference Model White Book 1998 was published.
The paper builds on the foundations laid down in "Preserving Digital Information: Report of the Task Force on Archiving of Digital Information" (1996), a watershed paper (http://www.rlg.org/ArchTF/index.html) commissioned by RLG and the Commission on Preservation and Access, as well as on the more recent Open Archival Information System (OAIS
) reference model advanced by the Consultative Committee for Space Data Systems (a 148-page July 2001 Adobe PDF document that's available at http://www.ccsds.org/rpa117/CCSDS650.0-R-2.pdf).
Their report, A Metadata Framework to Support the Preservation of Digital Objects (OCLC/RLG, 2002), expanded the conceptual structure for the Open Archival Information System (OAIS
) information model (Consultative Committee, 2002) and mapped preservation metadata elements to that conceptual structure.

Figure 1 presents an idealized repository workflow based on the Open Archival Information System (OAIS
) reference model (International Organization for Standardization, 2003).
Stanford University Libraries expects to use the TEAMS software as a core element of its "Dark Cave" project, which is intended to create a production implementation of the Open Archival Information System (OAIS
) reference model.
