The following paper is a prepublication version of a paper that is to appear in the journal Spatial Cognition and Computation in one of the 2007 issues. It contains our first published detailed example of using structured ontology modules for ontology construction and their application for spatial ontology.
Comments and suggestions are very welcome.
