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).
