OPTIQUE: Ontology−Based Data Access Platform

Abstract

Abstract. Ontology-Based Data Access (OBDA) is an approach to query rela-tional data via a unified semantic access point powered by an ontology that is ‘connected ’ to the underlying databases via mappings. OPTIQUE is an end-to-end OBDA platform. It offers support for semi-automatic bootstrapping of ontologies and mappings from relational databases thus facilitating system deployment, an intuitive interface to pose queries over a deployed system, and a query processing and optimisation module that allows to efficiently answer user queries. In this demonstration attendees will be able to experience OPTIQUE with data from the oil and gas industry and data from the music domain. 1
