The following may be of interest to those of you who are, or have been,
directly involved in development of /real/ domain ontologies (not just
toy ontologies and examples).
From the ontology development communities, there have been many
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 ---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
To this end, we have set up a questionnaire  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 . Interested
readers may like to play with the OBDA tools in their own lab already; a
pre-release can be downloaded from .
Also, if you would like to be involved in the testing, please do not
hesitate to contact undersigned and/or Mariano Rodriguez
