In scope

This document is applicable to:

- machine-interpretable PMI "Semantic Representation" (Refer to Clause 3 for definition);

- the association of the above with 3D geometric shapes;

- the possible association of the above with Presentation of 3D Product and Manufacturing Information (PMI), and 3D annotations as specified in EN 9300-120.

In EN 9300-121, the technology used to preserve this 3D information is based on semantic representation. The main use cases are Certification, Product Liability and Design re-use.

For the purpose of this document, the semantic definition is at the level that supports associative "Cross-highlighting" for the purpose of human readability.

Out of scope

This document is applicable to:

- PMI presentation (specified in EN 9300-120);

- User defined attributes that are assigned to 3D geometric entities or at the part level. The archiving of the UDA is specified in EN 9300-120.

- How to preserve additional information:

- property rights;

- form features;

- CAD Assemblies.

- The semantics of special Notes outside the scope of PMI: ITAR/EAR, proprietary, and title block information, etc.
