14、andards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. 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 o
15、rganizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules giv
16、en in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least
17、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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 21961 was prepared by the Consul
18、tative Committee for Space Data Systems (CCSDS) (as CCSDS 647.1-B-1, June 2001) and was adopted (without modifications except those stated in Clause 2 of this International Standard) by Technical Committee ISO/TC 20, Aircraft and space vehicles, Subcommittee SC 13, Space data and information transfe

32、 The Committee meets periodically to address data 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 no
33、t considered binding on any Agency. This Recommendation is issued by, and represents the consensus of, the CCSDS Plenary body. Agency endorsement of this Recommendation is entirely voluntary. Endorsement, however, indicates the following understandings: o Whenever an Agency establishes a CCSDS-relat
34、ed standard, this standard will be in accord with the relevant Recommendation. Establishing such a standard does not preclude other provisions which an Agency may develop. o Whenever an Agency establishes a CCSDS-related standard, the Agency will provide other CCSDS member Agencies with the followin
35、g information: The standard itself. The anticipated date of initial operational capability. The anticipated duration of operational service. o Specific service arrangements shall be made via memoranda of agreement. Neither this Recommendation nor any ensuing standard is a substitute for a memorandum
36、 of agreement. No later than five years from its date of issuance, this Recommendation will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to reflect the impact of new technologies, new requirements, or new directions; or, (3) be retired
37、or canceled. In those instances when a new version of a Recommendation is issued, existing CCSDS- related Agency standards and implementations are not negated or deemed to be nonCCSDS compatible. It is the responsibility of each Agency to determine when such standards or implementations are to be mo
38、dified. Each Agency is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommendation.

39、1 FOREWORD This Recommendation is a technical Recommendation that provides a model and language to increase the standardisation of the expression of semantic concepts that are to be carried with data. These semantic concepts are given standard names, and a standard way of expressing them is also pro
40、vided. The semantic information may be conveyed either in a computer- processable manner or via conventional (e.g., paper) documentation. Through the process of normal evolution, it is expected that expansion, deletion or modification to this document may occur. This Recommendation is therefore subj
41、ect to CCSDS document management and change control procedures defined in reference C1. Current versions of CCSDS documents are maintained at the CCSDS Web site: http:/www.ccsds.org/ Questions relative to the contents or status of this document should be addressed to the CCSDS Secretariat at the add
