BS EN 9300-004:2013

This standard BS EN 9300-004:2013 Aerospace series. LOTAR. Long Term Archiving and Retrieval of digital technical product documentation such as 3D, CAD and PDM data is classified in these ICS categories:

• 35.240.60 IT applications in transport
• 01.110 Technical product documentation
• 35.240.30 IT applications in information, documentation and publishing
• 49.020 Aircraft and space vehicles in general

This European Standard presents methods which are divided into four main categories: 1) scope and scenario description; 2) process description; 3) data; 4) system architecture. For scope and scenario description, the modelling methods are based on Unified Modelling Language (UML) Use Case diagrams. The process descriptions are done using Simplified Activity diagrams. Data modules are described by Express G diagrams. Rules and constraints are described via Express-Where-Rules. Further descriptions, for example, for a data dictionary, are based on tabular forms. To support the development of a system architecture, the modelling method of UML Package diagrams is used.
