Foreword

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 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 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, 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, 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. 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 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 following parts, under the general title Information technology — CDIF semantic metamodel:

• Part 1: Foundation
• Part 2: Common
• Part 3: Data definition
• Part 4: Data models
• Part 5: Data flow models
• Part 6: State/event models

Introduction

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 transferring information between tools.

ISO/IEC 15474-1:2002, Information technology — CDIF framework — 1: Overview, and ISO/IEC 15474-2:2002, Information technology — CDIF framework — 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 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 other 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.

This document is organized into the following Clauses:

• Clauses 1 to 5 are prescribed ISO/IEC Clauses
• Clause 6: Subject area overviewThis Clause gives an overview of the coverage of this subject area.
• Clause 7: Subject area summaryThis Clause gives an overview of the content of this subject area.
• Clause 8: Subject area specificationThis 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.

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 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 semantic 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 — 1: Overview. These standards cover the overall framework, the transfer format and the CDIF semantic metamodel.

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.

This standard defines the Common Subject Area of the CDIF semantic metamodel. This subject area contains meta-objects that are used as the basis of the other subject area standards, and also meta-relationships and meta-attributes that are applicable to all meta-objects.

This document is intended to be used by anyone wishing to understand and/or use CDIF. This document provides a definition of a single subject area of the CDIF semantic metamodel. It is suitable for:

• Those evaluating CDIF,
• Those who wish to understand the principles and concepts of a CDIF transfer, and
• Those developing importers and exporters.

This document, ISO/IEC 15474-1:2002, Information technology — CDIF framework — 1: Overview, and the Framework document ISO/IEC 15474-2:2002, Information technology — CDIF framework — 2: Modelling and extensibility, should be read first when initially exploring CDIF and before attempting to read other documents in the CDIF family of standards.

While there are no specific prerequisites for reading this document, it will be helpful for the reader to have familiarity with the following:

• Entity-Relationship-Attribute modelling;
• Modelling (CASE) tools;
• Information repositories;
• Data dictionaries;
• Multiple meta-layer modelling.
