Relational database mapping to Resource Description Framework (RDF) is a hot topic in semantic web study. Database reconstruction in relational database is often unavoidable. Database administrator often uses SQL view mechanism to maintain data logical independence in reconstructed database. This paper proposes a method of mapping to RDF from reconstructed relational database based on RDF view, which describes SQL view of reconstructed database and other base tables not involved with the view as RDF view supporting SPARQL-to-SQL query rewrite and conversion of SQL query result to RDF data.
