A dependency modeling approach for the management of ontology based integration systems

Ontology-based information integration systems have been proposed to solve the problem of combining data residing at autonomous and heterogeneous sources. For such ontology based solutions to succeed in an industrial context, the ontologies and mappings need to be managed to allow them to evolve as the data sources evolve. This paper describes a dependency modeling approach to the management of mappings in the integration system. A dependency model and tool have been prototyed within the context of a chellenging logistics based industrial systems integration problem.
