This paper proposes a solution for migrating an RDBMS into an appropriate structure for the Semantic Web (i.e., RDF). The solution takes an existing RDBMS 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 record sets of database are stored in an OWL document. A prototype has been implemented to demonstrate the practical applicability of the approach and show how the results of reasoning can help improve Web systems.

- Knows methods such as Direct Mapping of Relational Data to RDF (2012) for transforming data from the relational model (keys, values, rows, columns, tables) into RDF graphs.
- Knows Web Ontology Language, or OWL (2004), as a RDF vocabulary of properties and classes that extend support for expressive data modeling and automated inferencing (reasoning).
