This document defines the requirements for the long term digital preservation of the Semantic Representation of Product and Manufacturing Information (PMI) with their possible links to the 3D explicit shape and geometry of single CAD parts. The goal is to preserve this 3D information, without loss, with respect to the geometry produced by the original CAD system, following the principles laid down in EN 9300-003 “Fundamentals and Concepts”.
The requirements of EN 9300-110 concerning the preservation of the 3D explicit shape shall apply within this Part.
The term “semantic representation” is defined in Clause 3 “Terms, definitions and abbreviations”.
