The goal of this project is to develop a robust platform Ontology Based Data Access (OBDA) and to demonstrate the potential of this technology by deploying it in specific nanotechnology use cases relevant to industry and the research community.

The basic idea of OBDA is to use a lightweight ontology to provide a uniform conceptual model to improve access to data stored in one or more (typically relational) data stores. The assumption is that the schemas of these data stores will be heterogeneous and not intuitive for users; in contrast, the ontology will provide a single user oriented conceptual model. The research issues to be addressed in OBDA mainly relate to scalability and query formulation.

As opposed to the Ontolution project, OBDA explicitly does NOT plan to develop ontology engineering infrastructure, nor is it anticipated that much effort will be spent developing ontologies. Instead, partners in OBDA plan to adapt ontology as required for query answering. Hopefully this process will be at least semi-automatic, and when “old fashioned” ontology engineering is required partners in OBDA expect to exploit existing tools such as Protege.

Thus OBDA and Ontolution might be complementary, or even orthogonal. In particular, the OBDA platform should be of interest in any Ontolution data access application, and ontology engineering tools and techniques developed in Ontolution should be of interest in the OBDA platform.
