35、O/IEC 15474-1:2002(E) ISO/IEC 2002 All rights reserved vForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in t
36、he development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-g
37、overnmental, 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 Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. The main ta
38、sk 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. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a
39、 vote. Attention is drawn to the possibility that some of the elements of this part of ISO/IEC 15474 may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 15474-1 was prepared by Joint Technical Committee ISO/IEC JTC 1,
40、Information technology, Subcommittee SC 7, Software and system engineering. ISO/IEC 15474 consists of the following parts, under the general title Information technology CDIF framework: Part 1: Overview Part 2: Modelling and extensibility ISO/IEC 15474-1:2002(E) vi ISO/IEC 2002 All rights reserved I
41、ntroduction This standard will assist the vendors and users of modelling tools and meta-data repositories in developing mechanisms for interchanging information. This standard specifies an element of a family of related standards. When used together, these standards specify a mechanism for transferr
42、ing information between tools. This document, ISO/IEC 15474-1:2002, Information technology CDIF framework Part 1: Overview, describes the architecture of the CDIF family of standards and provides an overview to all the current standards that form the CDIF family of standards. The document ISO/IEC 15
43、474-2:2002, Information technology CDIF framework Part 2: Modelling and extensibility, explains the scope, and modelling approach in CDIF. It also defines the CDIF meta-metamodel and extensibility mechanism of CDIF. This document and the Framework for Modelling and Extensibility should be read first
44、 when initially exploring CDIF. 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 and the general requirements associated with interchanging information between these produc
45、ts. This document is organized into the following Clauses: Clause 1 to 5 are prescribed ISO/IEC Clauses Clause 6: CDIF Overview and architecture This Clause describes the scope, purpose, architecture, and fundamental concepts of CDIF. This Clause also describes the major components of the CDIF archi
46、tecture: the framework, the transfer format, and the semantic metamodel. Clause 7: CDIF Family of standards overview This Clause describes the components of the CDIF semantic metamodel. These components are presented as a series of subject areas that serve to address key areas of the Systems Develop
47、ment Life Cycle. INTERNATIONAL STANDARD ISO/IEC 15474-1:2002(E) ISO/IEC 2002 All rights reserved 11 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 facilitates a successful transfer when the
48、authors of the importing and exporting tools have nothing in common except an agreement to conform to CDIF. The CDIF family of standards includes a semantic metamodel and a transfer format definition. It also includes the specification of a meta-metamodel and associated rules that define a framework
49、 for the semantic metamodel and the transfer format. The language that is defined for the transfer format also has applicability as a general language for Import/Export for repositories. The CDIF semantic metamodel also has applicability as the basis of standard definitions for use in repositories. The diagram in Figure 1 depicts the various standards that comprise the CDIF family of standards. The shaded box depicts this Standard and its position in the CDIF family of standards. F
