Capturing and sharing design concepts is necessary if we want to support the design process by means of Information & Communication Technology (ICT). Standardized concepts are important for support at the end of the design process when designs need to conform to set standards and norms, and in order to enable communication, but are less useful in the early design stages. We propose an approach that takes into account a more developmental attitude that will be better suited for design support and the sharing of design concepts. In this approach, design concepts are formalised by means of a technology called concept modelling. Capturing and exchange of concepts are based on a multi-agent approach. The whole of concepts that are used in a domain or for a design task can be considered a design ontology. In this paper we outline the motivations for the research, outline the basic approach in the research work, and identify the major challenges and research problems that need to be tackled.
