Mappings for integrating design tools

The ability to integrate a range of disparate design tools has been an area of intense research throughout the world. One of the hardest tasks in this research has been to define the correspondences between the model of a building used by a design tool and the integrated data model. This paper presents a method of defining mappings between different models of a building. The implementation of a mapping management system which controls the flow of data between the varíous models and guarantees the consistency of the models is also described.
