Collaborative product commerce (CPC) is a newly emerging technology to support inter-enterprise collaboration through the product life-cycle. From the point of view of information technology, CPC is a software technology to integrate products, processes and resources of different enterprises using web technologies. In this paper, we propose a framework for integrating product information across enterprises, which is being developed by the Electronics and Telecommunications Research Institute (ETRI) as a part of a CPC project. The product metadata represented by an XML schema, which is compatible with the ISO STEP PDM (product Data Management) schema standard, is presented to semantically and schematically integrate distributed product information. Web services technologies are discussed to support the interoperability of application systems related to the product development, such as computer-aided design (CAD) and PDM, where most of these applications run in a distributed environment. Finally, we implement the framework to integrate distributed product information and application systems.

It is apparent that the development or implementation of a collaborative product development management (CPDM) system in an enterprise should be based on the right understanding of core domain objects, their main attributes, and their relationships to other objects in the product development domain. For this purpose, an object-oriented conceptual model of a CPDM system based on a top-down approach is presented in this paper. For building the conceptual model systematically, this paper proposes the 4P2C modeling views, which are multifaceted views of engineering information that provides an integrated and consistent perspective on engineering information. The 4P2C stands for product, process, project, participant, cost, and collaboration. Based on the 4P2C modeling views, six submodels are constructed that eventually constitute a complete conceptual CPDM model. In each sub-model, the decomposition of core domain objects, their main attributes, and their relationships to other objects are represented in detail. A prototype application program along with an illustrative cost calculation example is also presented to demonstrate that the proposed CPDM model will enable enterprises to maintain consistency in product data efficiently throughout the product life cycle.
