Capturing design knowledge in formal concept definitions

For support of creativity in architectural design, design systems must be provided with information models that are flexible enough to follow the dynamic way of designers in handling early design information. This paper discusses a framework for information modelling using Features that answers this need. One of the characteristics of the framework is that designers can define the formalisation of their own design concepts into types of Features. The defmition of these Feature Types can be done in different manners; three scenarios for this procedure are presented and discussed
