This paper addresses two fundamental aspects of concurrent engineering processes. It suggests the integration of component and product data. On the one hand, the Parts Library standard, denoted P-Lib, has been described for exchanging part libraries between CAD systems, which use a big amount of heterogeneous data related to components or parts. Its data model allows the capability to exchange complex data between library management systems: data schemas, queries, constraints, domains and methods are described in this P-Lib data model. On the other hand, Product Data Management systems, denoted PDM, have been defined, in the last decade, in order to manage thousands of heterogeneous data (CAD/CAM data, BoM etc.) related to products. Technical data management permits the management of the all-informational patrimony of a product starting from its design until its discharge. Products are essentially composed of pre-existing components stored in component or part libraries. This paper presents the approach we developed to integrate component data and product data. This approach has been applied with the particular standardised P-Lib data model for representing components and a particular PDM system namely SmarTeam. It will allow the automatically storage of component data in a PDM and the easy referencing of these data in the products during their whole lifecycle
