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.
