General

The Computer Graphics Metafile provides a file format suitable for the storage and retrieval of picture information. The file format consists of a set of elements that can be used to describe pictures in a way that is compatible between systems of different architectures and devices of differing capabilities and design.

The Model Profile, described in this part of ISO/IEC 12071, defines a subset of CGM elements, sets limits and generation and interpretation behaviour according to the rules for profile definition defined in ISO/IEC 8632. The Model Profile defines a version 3 CGM suitable for use in basic presentation and visualization, such as graphics arts, high end desktop publishing.

Position within the taxonomy

The Model Profile is one of four core profiles defined within the taxonomy for CGM profiles. These are shown in Figure 1 in diagramatic form. The diagram uses the following conceptual framework to define profiles:

• CGM version — this is a part of the standard and describes the group of elements available to the profile
• complexity of the problem

The four core profiles (as indicated in Figure 1) are:

This part of ISOLIEC ISP 1207 1 adopts the Model Profile defined in ISO/IEC 8632/Amd. 1.

User requirements and scenario

This part of ISO/IEC ISP 12071 provides a CGM version 3 profile suitable for basic presentation and visualization, such as graphics arts, high end desktop publishing. This ISP is equivalent to the Model Profile defined in ISOLIEC 8632/Amd. 1.
