This presents a systematic approach to the organisation of early stage design information, and the associated interactions among various types of representation. Scene-level representations are introduced as the complement of traditional object-level representations in an integrated information system. A cross-representational approach is proposed. The advantage of this approach is in the support of both user-definable representations, and cross-representational manipulations, including organisational transformation, information filtering, information aggregation, and simulations, which are essential for designers to dig into raw data. A prototype program called NetworkBuilder is being developed in order to explore the approach.
