Data Exchange is the problem of inserting data structured under a source schema into a target schema of different structure (possibly with integrity constraints), while reflecting the source data as accurately as possible. Our work presents an ontology-based method to exchange data among heterogeneous data sources. We use an extended DLs knowledge base to describe the data source schema, through adding constraint rules to maintain data integrity, and use an inferential way to exchange data instances between source schema and target schema. We also introduce an ebXML component to manage the data sources schema ontologies, in this way, our system has the ability of exchanging data instances among multi-kinds of data sources.
