1.1 In scope This document defines a Recommended Practice for Product Structure validation. The objective is to validate the product structure of data ingested, extracted or re-used by the archive. This document defines a method to uniquely identify each node in the product structure and to uniquely define the structure of each assembly node. 1.2 Out of scope This document will not provide validation properties for documents; CAD or other.

The following is in scope of this document: - business specification for long term archiving and retrieval of CAD 3D explicit geometry (see Clause 5); - essential information of CAD 3D explicit geometry (solids, curves, surfaces, and points) to be preserved (see Clause 6); - data structures detailing the main fundamentals and concepts of CAD 3D explicit geometry (see Clause 7); - verification rules to check CAD 3D explicit geometry for consistency and data quality (see Clause 8); - validation rules to be stored with the CAD 3D explicit geometry in the archive to check essential characteristics after retrieval (see Clause 9). NOTE 1 This document includes the geometrical external shape resulting from CAD 3D domain elements (e.g. 3D Structural components, 3D Tubing, 3D electrical harness, 3D composite, etc.). The following is outside the scope of this document: - the formal definition of validation and verification rules to check 3D explicit geometry for consistency and data quality using a machine-readable syntax; - implicit or parametric geometry; - Geometric Dimensioning and Tolerancing (GD&T), Product and Manufacturing Information (PMI); N0TE 2 For long term archiving of the GD&T and PMI see EN 9300 120, EN 9300 121 and EN 9300 125. - assembly structures and PDM product structures; NOTE 3 For long term archiving of assembly structure see EN 9300 115 and for product structure see EN 9300 2xx series. - model styling and organization of explicit geometry.
