Description / Abstract:
This International Standard defines the reference model for an
open archival information system (OAIS). An OAIS is an archive,
consisting of an organization, which may be part of a larger
organization, of people and systems that has accepted the
responsibility to preserve information and make it available for a
designated community. It meets a set of such responsibilities as
defined in this International Standard, and this allows an OAIS
archive to be distinguished from other uses of the term "archive".
The term "open" in OAIS is used to imply that this International
Standard, as well as future related International Standards, are
developed in open forums, and it does not imply that access to the
archive is unrestricted.
This International Standard
-provides a framework for the understanding and increased
awareness of archival concepts needed for long term digital
information preservation and access,
-provides the concepts needed by non-archival
organizations to be effective participants in the preservation
process,
-provides a framework, including terminology and concepts,
for describing and comparing architectures and operations of
existing and future archives,
- provides a framework for describing and comparing different
Long Term Preservation strategies and techniques,
-provides a basis for comparing the data models of digital
information preserved by archives and for discussing how data
models and the underlying information may change over time,
-provides a framework that may be expanded by other
efforts to cover long term preservation of information that is not
in digital form (e.g. physical media and physical samples),
-expands consensus on the elements and processes for long
term digital information preservation and access, and promotes a
larger market which vendors can support, and
-guides the identification and production of OAIS-related
standards.
The scope and field of application are furthermore detailed in
subclauses 1.1 and 1.2 of the enclosed CCSDS publication.
