CPM 2: A Revised Core Product Model for Representing Design Information



Steven J. Fenves, Sebti Foufou, Conrad Bock, Roger Bouillon, Ram D. Sriram


This report presents a revised version of the Core Product Model (CPM) initially reported in [1]. The objectives of the report are: (1) to document the changes in the CPM relative to the first version; (2) to describe in detail the revised CPM, represented as a Universal Modeling Language (UML) class diagram; (3) to show, throughout Java and eXtensible Markup Language (XML) implementations, how the CPM can be used as the basis, or organizing principle, of a product information-modeling framework that can support the full range of product design information; and (4) to present a rational, model-based process for converting a CPM supporting early conceptual phases of design into an implementation-level operational database support system. UML, XML and Java representations of the model are presented so as to provide interoperability with other models. A case study example is discussed and its XML representation is presented and analyzed to illustrate the principal elements of the revised CPM.
