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.

This document has been declared "Stabilized" and will no longer be subjected to periodic reviews for currency. Users are responsible for verifying references and continued suitability or technical requirements. New technology may exist. This document specifies the CLARA interfaces of the CLAR Truth Data Generator. The objective for the CLAR Truth Data Generator is to produce impact data sets to be used in the CLAR Coefficient Generator first to score and form LAR boundaries, and then to generate coefficients. A model of the weapon system that predicts weapon delivery performance to a predefined accuracy is to be used for this purpose. The model can be the Six-Degree-Of- Freedom (6DOF) equations of motion or another mathematical representation that meets the objective for the weapon system LAR.
