Description grammars: A general notation

Abstract

A description grammar, in conjunction with a shape grammar, serves to generate verbal descriptions of designs, next to the spatial descriptions. These verbal descriptions can also assist in guiding the generative process. This paper presents a general notation for descriptions and description rules that accounts, extensively if not entirely, for many of the applications of description grammars found in literature. Specifically, a review of the notation with respect to these description schemes supports the explication of its strengths and limitations and the identification of future work. A follow-up paper revisits selected applications of description grammars and demonstrates the applicability of this general notation to these case studies.
