CPM 2:

Abstract

This report presents a revised version of the Core Product Model (CPM) initially reported in [1].The initial CPM was intended to provide a base-level product model that is: not tied to any specific application or software; open; non-proprietary; simple; generic; expandable; independent of any product development process; and capable of capturing all product information shared throughout the product's lifecycle.The revisions presented continue to support these intentions.The objectives of the report are: (1) to document the changes in the CPM relative to the initial version; (2) to describe in detail the revised CPM, represented as a UML class diagram; (3) to show, through Java and 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 the 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.
