Ontological representation of heterogeneous datasources integration knowledge for the semantic Web

To make the integration knowledge of heterogeneous datasources sharable on the Semantic Web, an impor tant aspect to be fulfilled is related to the capabil ity of organizing such a knowledge as an ontology for the considered datasources. In this paper, we describe the integration knowledge organization for the Seman tic Web with reference to the integration process per formed by the artemis tool environment. We address the problem of deriving a Semantic Web-compatible representation of the integration knowledge using the DAML+OIL ontology.
