The vision of the SemanticWeb can only be realized through proliferation
of well-known ontologies describing different domains. To
enable interoperability in the Semantic Web, it will be necessary to
break these ontologies down into smaller, well-focused units that
may be reused. Currently, three problems arise in that scenario.
Firstly, it is difficult to locate ontologies to be reused, thus leading
to many ontologies modeling the same thing. Secondly, current
tools do not provide means for reusing existing ontologies while
building new ontologies. Finally, ontologies are rarely static, but
are being adapted to changing requirements. Hence, an infrastructure
for management of ontology changes, taking into account dependencies
between ontologies is needed. In this paper we present
such an infrastructure addressing the aforementioned problems.
