This clause:
a) defines the concept of profiles of ISO/IEC 8632;
b) provides rules for defining profiles of ISO/IEC 8632;
c) provides conformance criteria for profiles of ISO/IEC 8632;
d) provides conformance criteria for metafiles, metafile generators, and metafile interpreters;
e) defines criteria on which to evaluate profiles of ISO/IEC 8632;
f) provides a Profile Proforma (PPF) and Model Profile.
This clause addresses the CGM data stream and implementation requirements. Implementation requirements address the latitude allowed by CGM generators and interpreters. This clause does not directly address the environmental, performance, or resource requirements of the generator or interpreter.
This clause does not define the application requirements or dictate application functional content of a profile — the latter is the purview of application constituencies.
The scope of this clause is limited to rules for valid profiles for open interchange of graphical picture metafiles.
