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.
