Semantic mapping: ontology-based vs. model-based approach Alternative or complementary approaches?

Model transformation and semantic mapping are enabling technologies for new, advanced solutions to address enterprise software interoperability. Such technlogies are nowdays tackled by two different disciplines: software architectures, with the MDA approach, and semantic interoperability, with an ontology-based approach. This paper briefly compares the model-based (MB) and the ontology-based (OB) approaches and draws some preliminary conclusions on similarities and differences, in the perspective of combining these approaches in a value-adding way.
