40、dization) and IEC (the International Electrotechnical Commission) form the specialized 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 organizatio
41、n 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-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, IS
42、O 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 task of the joint technical committee is to prepare International Standards. Draft International Standards adopted
43、 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 vote. Attention is drawn to the possibility that some of the elements of this part of ISO/IEC 15476 may be the
44、subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 15476-2 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and system engineering. ISO/IEC 15476 consists of the follow

This standard specifies an element of a family of related standards. When used together, these standards specify a mechanism for transferring information between too
47、ls. ISO/IEC 15474-1:2002, Information technology CDIF framework Part 1: Overview, and ISO/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 fami
48、ly of standards fits together. The second explains the scope, and modelling approach in CDIF. The CDIF meta-metamodel and extensibility mechanism are also defined in that document. This standard explains the Common subject area of the CDIF semantic metamodel, that defines information common to all o
49、ther objects in the semantic Meta-model. The CDIF semantic metamodel is used to ensure that the information transferred by tools communicating using CDIF is expressed with an agreed meaning. 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 products.
