scope:

This document defines a set of metadata to support the audit trail of the transformation of a geometry definition, while it is distributed and shared in supply-chains, to ensure the traceability of geometric model data. It also defines a set of web services based on the utilisation of these metadata. The following are within the scope of this document: -     metadata definitions for geometry transformation audit trail: -     syntax for storing these metadata in geometry data sets in various formats; -     conformance level for implementers and business processes; -     definitions of web services to query the geometric model data set and its associated metadata. The following are outside the scope of this document: -     service specifications for CAD operations; -     specifications of a cybersecurity infrastructure to enable web services; -     the technical implementation of a STEP geometry services client or server; -     any geometric model definition; -     any product and manufacturing information (PMI) definition; -     archiving.
