Dear All, Having listened to the requests for scalable ontologies and ontology-driven information systems, we—at the universities La Sapienza and Bolzano, as participant and leader of the EU FP6 TONES Project [1]—have developed such tools. That is, we know that both in theory and with test data, the tools for Ontology-Based Data Access (OBDA) perform significantly better, but we would like to examine that against real data—the bigger the amount of data and ontology you have, the better. While at this time we’ll not disclose the precise hypotheses, they obviously revolve around the practical aspects of the trade-off between expressiveness of the ontology language and efficient, scalable computation. To this end, we have set up a questionnaire [2] about usage and feature requests, of which we hope you will take the 5 minutes to complete, and we will test with bio-ontologies that are—or wish to be—linked to databases to assess things like performance of (conjunctive) query answering and instance classification. An informal description with links to the main references of some of the tools and their theoretical foundations is available at [3]. Interested readers may like to play with the OBDA tools in their own lab already; a pre-release can be downloaded from [4]. Also, if you would like to be involved in the testing, please do not hesitate to contact undersigned and/or Mariano Rodriguez (mrodriguez@inf.unibz.it).
