Executive Summary

Early validation of requirements is crucial for the rigorous development of software. Without it, even the most formal of the methodologies will produce the wrong outcome. One successful approach, popularised by some of the so-called lightweight formal methods, consists in generating (finite, small) models of the specifications. Another possibility is to build a running prototype from those specifications. In this paper, the authors show how to obtain executable prototypes from formal specifications written in an object oriented notation by translating them into logic programs. This has some advantages over other lightweight methodologies. For instance, they recover the possibility of dealing with recursive data types as specifications that use them often lack finite models.
