Mapping Relational Database into OWL Structure with Data Semantic Preservation

This paper proposes a solution for migrating an RDB into Web semantic. The solution takes an existing RDB as input, and extracts its metadata representation (MTRDB). Based on the MTRDB, a Canonical Data Model (CDM) is generated. Finally, the structure of the classification scheme in the CDM model is converted into OWL ontology and the recordsets of database are stored in owl document. A prototype has been implemented, which migrates a RDB into OWL structure, for demonstrate the practical applicability of our approach by showing how the results of reasoning of this technique can help improve the Web systems.
