SQuaRE: A Visual Approach for Ontology-Based Data Access

We present the SPARQL Query and R2RML mappings Environment (SQuaRE) which provides a visual interface for creating mappings expressed in R2RML. SQuaRE is a web-based tool with easy to use interface that can be applied in the ontology-based data access applications. We describe SQuaRE’s main features, its architecture as well as implementation details. We compare SQuaRE with other similar tools and describe our future development plans.
