2.  The name of your system, a URL for its website (if any), and a one-sentence

QuOnto - http://www.dis.uniroma1.it/~quonto/
QuOnto is an OWL 2 QL and DLLite reasoner.

3.  Which profile(s) it implements (DL, EL, QL, RL, or Full).  We
   would appreciate some brief commentary about why you chose those
   profiles, and what sort of implementation techniques you are

QuOnto was originally born as a DLLite implementation. Since the OWL 2
QL profile is based on DLLite, we built a version of QuOnto
specifically tailored for OWL 2 QL.

4.  Which semantics you implement (direct or rdf-based), and
   (optionally) why.

We implement direct semantics.

5.  Do you believe your system currently conforms to the OWL 2
   Candidate Recommendation?  Does it pass all the test cases for
   your profile?  If not, which features does it lack and/or which
   test cases does it not yet pass?  Do you have plans to make it
   conformant, and make it pass all the test cases?

We believe that QuOnto is fully conformat, for a restricted set of
datatypes. It passes all required
tests and extra credit tests. Notice that tests actually marked with
*not reported* on the public test case page [1], have been added after
we sent the first results; anyway, we succesfully performed also that

6.  Did you implement the "at risk" features, owl:rational and
   rdf:XMLLiteral?  If not, do you intend to, or do you think we
   should remove them from OWL 2?

QuOnto does not support rationals and rdf:XMLLiteral, but we intend to.

7.  Finally, we'd appreciate your evaluation of whether the OWL 2
   Candidate Recommendation is ready to proceed along the standards
   track toward being a W3C Recommendation.  If not, please be sure
   to tell us what problems you think we need to address.

We see no problems with proceeding to Recommendation.
