<p>The CDIF family of standards is primarily designed to be used as a description of a mechanism for transferring</p>
<p>information between modelling tools. It facilitates a successful transfer when the authors of the importing and</p>
<p>exporting tools have nothing in common except an agreement to conform to CDIF. The language that is defined for</p>
<p>the transfer format also has applicability as a general language for Import/Export from repositories. The CDIF</p>
<p>semantic metamodel defined for modelling tools also has applicability as the basis of standard definitions for use in</p>
<p>repositories.</p>
<p>The standards, which form the complete family of CDIF Standards, are documented in ISO/IEC 15474-1:2002,</p>
<p><i>Information technology — CDIF framework — Part 1: Overview. </i>These standards cover the overall framework,</p>
<p>the transfer format and the CDIF semantic metamodel.</p>
<p/>
<p><b>Figure 1 </b>− <b>Position in the CDIF family of standards</b></p>
<p>The diagram in Figure 1 depicts the various standards that comprise the CDIF family of standards. The shaded box</p>
<p>depicts this Standard and its position in the CDIF family of standards.</p>
<p>This document describes the standard CDIF Transfer Encoding for the standard CDIF Transfer Syntax as defined</p>
<p>in ISO/IEC 15475-2:2002, <i>Information technology —CDIF transfer format — Part 2: Syntax SYNTAX.1</i>.</p>
<p>This document is intended to be used by anyone wishing to understand and/or use CDIF. This document provides</p>
<p>an introduction to the entire CDIF family of standards. It is suitable for:</p>
<p>— Those evaluating CDIF,</p>
<p>— Those who wish to understand the principles and concepts of a CDIF transfer, and</p>
<p>— Those developing importers and exporters.</p>

<p>ISO/IEC 15474-2:2002, <i>Information technology — CDIF framework — Part 2: Modelling and extensibility </i>should be</p>
