Talk:Ontology-based data integration

I think, it's wrong, that "It is one of the multiple data integration approaches and may be classified as Local-As-View (LAV)" - I think, using of ontologies in data integration system doesn't say that it uses GAV, LAV, GLAV or some other approach. As I understand, SIMS, for example uses GAV approach to data integration and Piazza - GLAV. Am I wrong?
