Using a layered approach for interoperability on the semantic Web
I.F. Cruz, Huiyong Xiao · 2004
In this paper, we further develop a proposed layered approach for the semantic Web. Our objective is to build a specific solution to the problem of providing data interoperability among different databases, so as to allow for schematic data integration. In particular, we solve the problem of translating queries on a database schema into queries on another database schema, using their relationship with an ontology. We use RDF schema to model the databases and the ontology. A common vocabulary expresses the mappings between each database schema and the ontology.
