In the manufacturing industry Product Data Management (PDM) systems are backbone systems. As such they have to support the collaborative creation, management, dissemination, and use of product definition information across the extended enterprise from concept to end of life -integrating people, processes, business systems, and information. A drawback is that today's PDM systems are focussed on mechanical engineering. There is however an increasing need, for instance from aerospace industry, for an extended PDM system, which covers systems engineering product aspects.For storing information in a PDM system a data base schema is necessary. Most of PDM systems base on something like the "PDMschema". It is only restricted suitable for a systems engineering environment. STEP ISO 10303 -AP233 provides an appropriate approach for integrating systems engineering needs into PDM systems, specifically future modularised STEP ISO 10303 application protocols will make it possible to construct the required PDM schema extensions at reduced customisation effort. A framework for a systems engineering PDM system is proposed and data exchange aspects discussed. A demonstrator for the proposed solution was build using AP233 gateways for systems engineering CASE tools coupled to an appropriate PDM system.

Abstract. In industry, product data exchange via STEP ISO 10303, is an established method. In case of heterogeneous CASE Tools, e.g. in Systems Engineering applications, it is very often difficult to guarantee a defined level of data quality. This paper analyses the state of data transformation and exchange as well as offering a solution for schema mapping and integration by means of a transformation report which can be used in systems engineering. The report records individual transformation steps, during the exchange, between two different tools. It supports the understanding of the data exchange process and helps to rectify incomplete or incorrect transformed data. The proposed framework was validated using gateways between the Statemate and Teamwork CASE tools.
