** OWL 2 Implementation report - QuOnto **

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

QuOnto - http://www.dis.uniroma1.it/~quonto/ <http://hermit-reasoner.com>
QuOnto is an OWL 2 QL 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[_A] implementation. Being the OWL 2 QL profile 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.

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.
