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 modelling tools 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 the overall framework,

the transfer format and the CDIF semantic metamodel.

Figure 1 Position in the CDIF family of standards

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 document describes the standard CDIF transfer syntax. No encodings for SYNTAX.1 are specified in this

document. ISO/IEC 15475-3:2002, Information technology — CDIF transfer format — Part 3: Encoding

ENCODING.1, specifies one standard encoding for this syntax.

This document is intended to be used by anyone wishing to understand and/or use CDIF. This document provides

an introduction to the entire CDIF family of standards. 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.

The documents 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 and before attempting to read other documents in the CDIF family of

standards.

This document should be read in conjunction with ISO/IEC 15475-1:2002, Information technology — CDIF transfer

format — Part 1: General rules for syntaxes and encodings.

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;

— Formal grammars;

— Transfer formats.
