18、ion for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technical committees established by the respect
19、ive organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work. In the field of information
20、 technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodie
21、s casting a vote. International Standard ISOAEC 14863 was prepared by ECMA (as Standard ECMA-208) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of IS0 and IEC. Annexes A to
22、 C form an integral part of this International Standard. Annexes D and E are for information only. ISO/IEC 14863:1996 (E) = 4853903 Ob42325 58b o ISO/IEC Introduction The System Independent Data Format Association (SIDF) was formed in early 1993 by a consortium of industries. ECMA TC15 adopted the w
23、ork of this committee in early 1994 and developed Standard ECMA-208 on the basis of the SIDF specification. vi = 4853903 0642326 Y12 m INTERNATIONAL STANDARD OISfiEC ISO/IEC 14863:1996 (E) Information technology - System-Independent Data Format (SIDF) Section 1 - General 1 Scope This International S
24、tandard specifies a logical format for information interchange and secondary data storage. The format provides a System-Independent Data Format (SIDF) for the representation of primary file system information. This information includes, among other things, data, attributes and characteristics. This
25、International Standard specifies - the organization of the information on target media, - requirements for originating and receiving systems for the processing of the information. 2 Conformance 2.1 Conformance of Media Volumes A Volume shall be in conformance with this International Standard if all
26、information recorded on it meets the relevant requirements of sections 2 and 3 for the level of partition claimed. 2.2 Conformance of an originating system An originating system shall be in conformance with this International Standard if it meets the requirements of 14.2. 2.3 A receiving system shal
27、l be in conformance with this International Standard if it meets the requirements of 14.3 for the Level of conformance claimed. Conformance of a receiving system 3 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this Int
