Ontological Modularity and Spatial Diversity

In this paper we propose that adequate treatments of space need to be multiperspecti- val and related to sound foundational ontologies. To support this, we show that natural spatial descriptions commonly appeal to diverse theories of space and these need to be formally combined to be fully interpreted. Our account draws particularly on the foundational ontology DOLCE and the algebraic specification language CASL. We show how the structuring mechanisms of CASL suggest mechanisms for both build- ing and combining multiperspectival ontologies of space. We also suggest that these mechanisms provide a natural link both with currently emerging cognitive principles such as blending and with developments in ontology mediation and mapping.
