ISO/TS 23301:2021

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.
