Abstract

The compositional approach where several existing ontologies are connected to form a large modular ontology relies on the representation of mappings between elements in the different participating ontologies. A number of languages have been proposed for this purpose that extend existing logical languages for ontologies in a non-standard way. In this chapter, we compare different proposals for such extensions on a formal level and show that these approaches exhibit fundamental differences with respect to the assumptions underlying their semantics. In order to support application developers to select the right mapping language for a given situation, we propose a mapping metamodel that allows us to encode the formal differences on the conceptual level and facilitates the selection of an appropriate formalism on the basis of a formalism-independent specification of semantic relations between different ontologies by means of a graphical modelling language.
