Annotation of standard text ČSN EN 9300-121 (310450):
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. 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
