11、nal standards 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. Internati
12、onal organizations, 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 rul
13、es given 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
14、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 subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 13527 was prepared by the Consultative Committee
15、for Space Data Systems (CCSDS) (as CCSDS 661.0-B-1, September 2008) 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 transfer systems.

This International Standard also provides a detailed specification of core packaging structures and mechanisms, which accommodate the current computing environment and m

This International Standard is applicable to the entire space informatics domain, from operational messaging to interfacing with science archives. 2 Requirements Requirements are the technical recomm

29、CCSDS) is an organization officially established by the management of its members. 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
30、 voluntary, the results of Committee actions are termed Recommended Standards and are not considered binding on any Agency. This Recommended Standard is issued by, and represents the consensus of, the CCSDS members. Endorsement of this Recommendation is entirely voluntary. Endorsement, however, indi
31、cates the following understandings: o Whenever a member establishes a CCSDS-related standard, this standard will be in accord with the relevant Recommended Standard. Establishing such a standard does not preclude other provisions which a member may develop. o Whenever a member establishes a CCSDS-re
32、lated standard, that member will provide other CCSDS members with the following 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. N
33、either this Recommended Standard nor any ensuing standard is a substitute for a memorandum of agreement. No later than five years from its date of issuance, this Recommended Standard will be reviewed by the CCSDS to determine whether it should: (1) remain in effect without change; (2) be changed to
34、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 Standard is issued, existing CCSDS-related member standards and implementations are not negated or deemed to be non-CCSDS compatible. It
35、is the responsibility of each member to determine when such standards or implementations are to be modified. Each member is, however, strongly encouraged to direct planning for its new standards and implementations towards the later version of the Recommended Standard. BS ISO 13527:2010ISO 13527:201

37、ocument or message) to facilitate information transfer and archiving. It provides a detailed specification of core packaging structures and mechanisms that meet current CCSDS agency requirements and that augment the current CCSDS packaging and language Recommended Standards to accommodate the curren
38、t computing environment and meet evolving requirements. This Recommended Standard leverages the wide community acceptance and usage of XML technologies by making the packaging manifest an XML document defined by the XML Schema specified in this Recommended Standard. Through the process of normal evo
39、lution, it is expected that expansion, deletion, or modification of this document may occur. This Recommended Standard is therefore subject to CCSDS document management and change control procedures, which are defined in the Procedures Manual for the Consultative Committee for Space Data Systems.

The complete and ruling XML Schema for the XFDU Manifest can be found in section 11. b) Each XML Schema section contains both an XML Authority schema diagram and the W3C XML Schema Language specification of a high-level type. The developers of XML Authority Schema diagrams have decided on
49、 the following specific XML visualizations: Expand declared attribute groups that are specified once and referenced many times in the W3C XML Schema Language Specification. For this reason it may appear that the XML Schema Diagrams have more specified attributes than the corresponding W3C XML Schema language specifications. #wildcard is used by XML Authority schema diagrams to indicate open content and is the diagrammatic form of #any in the
