The chapter shows how minimal assumptions on difficult philosophical questions suffice for an engineering approach to the semantics of geospatial information. The key idea is to adopt a conceptual view of information system ontologies with a minimal but firm grounding in reality. The resulting constraint view of ontologies suggests mechanisms for grounding, for dealing with uncertainty, and for integrating folksonomies. Some implications and research needs beyond engineering practice are discussed.
