34、 system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committe

35、es collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International S

36、tandards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Public

37、ation as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this part of ISO/IEC 15476 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying an

38、y or all such patent rights. ISO/IEC 15476-1 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and system engineering.

40、oping mechanisms for interchanging information. This standard specifies an element of a family of related standards. When used together, these standards specify a mechanism for transferring information between tools. ISO/IEC 15474-1:2002, Information technology CDIF framework Part 1: Overview, and I

41、SO/IEC 15474-2:2002, Information technology CDIF framework Part 2: Modelling and extensibility, should be read first when initially exploring CDIF. The first explains the overall CDIF architecture and how the family of standards fits together. The second explains the scope, and modelling approach in

42、 CDIF. The CDIF meta-metamodel and extensibility mechanism are also defined in that document. This standard explains the Foundation subject area of the CDIF semantic metamodel, which is used to ensure that the information held by tools communicating using CDIF express the information they pass with

43、an agreed meaning. This subject area contains the basic objects on which all others, including extensions, must be based. This standard has been developed with the wide support and participation of vendors, users, academia and government involved in or familiar with the CASE industry, its products a

44、nd the general requirements associated with interchanging information between these products. This document is organized into the following Clauses: Clauses 1 to 5 are prescribed ISO/IEC Clauses Clause 6: Subject area overview This Clause gives an overview of the coverage of this subject area. Claus

45、e 7: Subject area summary This Clause gives an overview of the content of this subject area. Clause 8: Subject area definition This Clause gives the formal specification of all the objects defined in the subject area, and the formal reference to those used, but not defined in the subject area.

46、NATIONAL STANDARD ISO/IEC 15476-1:2002(E) ISO/IEC 2002 All rights reserved 1Information technology CDIF semantic metamodel Part 1: Foundation 1 Scope The CDIF family of standards is primarily designed to be used as a description of a mechanism for transferring information between modelling tools. It

47、 facilitates a successful transfer when the authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for the transfer format also has applicability as a general language for import/export from repositories. The CDIF sema

48、ntic metamodel defined for CASE also has applicability as the basis of standard definitions for use in repositories. The standards which form the complete family of CDIF standards are documented in ISO/IEC 15474-1:2002, Information technology CDIF framework Part 1: Overview. These standards cover th

49、e overall framework, the transfer format and the CDIF semantic metamodel. 15476 CDIF semantic metamodel 15474 CDIF framework Part 1 : Overview Part 2 : Modelling and extensibility Part 1 : Foundation Part 6 : State/event models Part 3 : Data definitions Part 4 : Data models Part 5 : Data flow models 15475 CDIF transfer format Part 1 : General rules for syntaxes and encodings Part 2 : Syntax SYNTAX.1 Part 3 : Encoding ENCODING.1 Part n : .
