MASTRO STUDIO: Managing Ontology-Based Data Access applications

Ontology-based data access (OBDA) is a novel paradigm for ac-cessing large data repositories through an ontology, that is a formal description of a domain of interest. Supporting the management of OBDA applications poses new challenges, as it requires to provide effective tools for (i) allowing both expert and non-expert users to analyze the OBDA specification, (ii) collaboratively documenting the ontology, (iii) exploiting OBDA services, such as query answer-ing and automated reasoning over ontologies, e.g., to support data quality check, and (iv) tuning the OBDA application towards op-timized performances. To fulfill these challenges, we have built a novel system, called MASTRO STUDIO, based on a tool for auto-mated reasoning over ontologies, enhanced with a suite of tools and optimization facilities for managing OBDA applications. To show the effectiveness of MASTRO STUDIO, we demonstrate its usage in one OBDA application developed in collaboration with the Italian Ministry of Economy and Finance
