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.
