Dynamic data sharing in a collaborative design environment

Based on expert engineering and collaborative work tools, the digital modelling of product development should now be realized in the context of life-cycle management. The objective is to develop a collaborative engineering design system and this paper focuses on the support of the dynamic sharing of design information as the main structuring element of collaboration. To enable information multi-representation, granularity expression, semantic encapsulation, updating and reuse, the design environment connects existing engineering tools and the specifically developed missing element able dynamically to share the data among designers.
