Validation Testing System Reusable Software Component Design



KC Morris, David A. Sauder, Sanford P. Ressler


The ISO STandard for the Exchange of Product model data (STEP) addresses the need to share data across multiple enterprises and hardware platforms by providing information models which clearly and unambiguously describe data. The validity of these information models is essential for success in sharing data in a highly automated business environment. The design of software, which supports the testing of these information models of validity and correctness, is described in this document. This design follows requirements and an architecture described in previously published documents about the validation Testing System (VTS) project. The collection of these documents provide a basis for software development within the National PDES Testbed. The software libraries described in this document may be reused in a number of STEP applications. The Testbed is used to validate information models for STEP. The scope of this document is limited to the design of those components of VTS software scheduled for development in the initial phase of the project.
