Ontology formalism transformation

This article deals with the problem how to transform an ontology between different formalisms. The presented methodology requires defining meta-models of the source and the target formalisms and defining a mapping between them. This allows us then to convert any ontology encoded in the source formalism to the target one. It is further shown that an extension of the SumatraTT system can be used to implement such transformations easily. The research presented in the paper has been motivated by the needs of the CIPHER research project (Communities of Interest Promoting Heritage of Europian Regions).
