Abstract
The complexity and richness of geospatial data and the difficulty
of their representation create specific problems for geographic
information systems interoperability. This paper proposes the
creation of software components from ontologies as a way to share
knowledge and data. These software components are derived from
ontologies using an object-oriented mapping. The translation of
ontologies into active information system components leads to
ontology-driven geographic information systems. The combined use of
diverse ontologies and multiple inheritance leads to a discussion
of implementation issues, such as the use of Ontolingua as an
ontology editor, and CORBA, and Java as object platforms.
