<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.</p>
<p>The CDIF family of standards includes a semantic metamodel and a transfer format definition. It also includes the</p>
<p>specification of a meta-metamodel and associated rules that define a framework for the semantic metamodel and</p>
<p>the transfer format. The language that is defined for the transfer format also has applicability as a general language</p>
<p>for Import/Export for repositories. The CDIF semantic metamodel also has applicability as the basis of standard</p>
<p>definitions for use in repositories.</p>
<p>The standards that form the complete family of CDIF Standards are documented in ISO/IEC 15474-1:2002<i>,</i></p>
<p><i>Information technology - CDIF framework - Part 1: Overview</i>. These standards cover the overall framework, the</p>
<p>transfer format and the CDIF semantic metamodel.</p>

<p><b>Figure 1 </b>− <b>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>This document (ISO/IEC 15474-2:2002<i>, Information technology - CDIF framework - Part 2: Modelling and</i></p>

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