Abstract

This paper addresses the data modeling aspect of an integrated product data-sharing environment (IPDE) based on the international standard STEP. The IPDE involves multiple design and analysis applications that require data from several STEP Application Protocols (AP203, 209, 214, 224) and integrated resources from different parts of STEP. Issues that were addressed include data granularity, interoperability of STEP-AP's, partitioning the AP's into units of functionality (UoF), and resolving inter-object references among UoFs. The consolidated data model used for progressive implementation of several prototypes is presented in this paper. Because of limitations of STEP, extensions beyond STEP were necessary for data related to aerodynamic analysis, parametric geometry and constraints. The latter were imported from the ENGEN (ENGEN is a DARPA supported collaborative project managed by PDES, Inc.) Data Model and a new STEP-compliant model was created for CFD. This paper may be regarded as a study of issues related to the synthesis of an integrated data schema from multiple independent topical models.
