Mapping relational databases to RDF is a fundamental problem for the development of the Semantic Web. We present a solution, inspired by draft methods defined by the W3C where relational databases are directly mapped to RDF and OWL. Given a relational ...
D2RQ is a popular RDB-to-RDF mapping platform that supports mapping relational databases to RDF and posing SPARQL queries to these relational databases. However, D2RQ merely provides a read-only RDF view on relational databases. Thus, we introduce D2RQ/...
This paper presents a feature-complete translation from SPARQL, the proposed standard for RDF querying, into efficient SQL. We propose "SQL model"-based algorithms that implement each SPARQL algebra operator via SQL query augmentation, and generate a ...
