8、2012ISO 14721:2012(E) ISO 2012 All rights reserved iiiForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.
9、Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Internat
10、ional Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Stand
11、ards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subjec
12、t of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14721 was prepared by the Consultative Committee for Space Data Systems (CCSDS) (as CCSDS 650.0-M-2, June 2012) and was adopted (without modifications except those stated in Clause 2 of this Inte
13、rnational Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfer systems. This second edition cancels and replaces the first edition (ISO 14721:2003), which has been technically revised. BS ISO 14721:2012BS ISO 14721:2012INTER
14、NATIONAL STANDARD ISO 14721:2012(E) ISO 2012 All rights reserved 1Space data and information transfer systems Open archival information system (OAIS) Reference model 1 Scope This International Standard defines the reference model for an open archival information system (OAIS). An OAIS is an archive,
15、 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
16、 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 unrestric
17、ted. 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 proce
18、ss, 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 da
19、ta 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 an
20、d 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 furth

30、721:2012CCSDS RECOMMENDED PRACTICE FOR AN OAIS REFERENCE MODEL CCSDS 650.0-M-2 Page ii June 2012 STATEMENT OF INTENT The Consultative Committee for Space Data Systems (CCSDS) is an organization officially established by the management of its members. The Committee meets periodically to address data
31、systems problems that are common to all participants, and to formulate sound technical solutions to these problems. Inasmuch as participation in the CCSDS is completely voluntary, the results of Committee actions are termed Recommendations and are not in themselves considered binding on any Agency.
32、CCSDS Recommendations take two forms: Recommended Standards that are prescriptive and are the formal vehicles by which CCSDS Agencies create the standards that specify how elements of their space mission support infrastructure shall operate and interoperate with others; and Recommended Practices tha
33、t are more descriptive in nature and are intended to provide general guidance about how to approach a particular problem associated with space mission support. This Recommended Practice is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommended Practice is enti
34、rely voluntary and does not imply a commitment by any Agency or organization to implement its recommendations in a prescriptive sense. No later than five years from its date of issuance, this Recommended Practice will be reviewed by the CCSDS to determine whether it should: (1) remain in effect with
35、out change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or (3) be retired or canceled. In those instances when a new version of a Recommended Practice is issued, existing CCSDS-related member Practices and implementations are not negated or deemed t
36、o be non-CCSDS compatible. It is the responsibility of each member to determine when such Practices or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new Practices and implementations towards the later version of the Recommended Practice.

38、 permanent, or indefinite Long Term, preservation of digital information. This Recommended Practice establishes a common framework of terms and concepts which make up an Open Archival Information System (OAIS). It allows existing and future archives to be more meaningfully compared and contrasted. I
39、t provides a basis for further standardization within an archival context and it should promote greater vendor awareness of, and support of, archival requirements. CCSDS has changed the classification of Reference Models from Blue (Recommended Standard) to Magenta (Recommended Practice). Through the
40、 process of normal evolution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Practice is therefore subject to CCSDS document management and change control procedures, which are defined in the Procedures Manual for the Consultative Committee for
41、Space Data Systems.
