OWL 2 Implementation report for OWLlink


we would be happy if OWLlink could be listed under the category APIs  
at <http://www.w3.org/2007/OWL/wiki/Implementations>.

OWLlink (<http://www.owllink.org/) is an implementation-neutral  
protocol for communication
between OWL 2 components. It specifies how to manage reasoning engines  
and their
knowledge bases, how to assert axioms, and how to query inference  
results. OWLlink is
extensible and allows to add required functionality to the protocol on  

We are currently in the process of revising the OWLlink specification  
as of October 2008 (based on the OWL 2 Specification of April 11th  
2008) and plan to release an update this October, which will be fully  
aligned with the final OWL 2 Specification.

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

Name: OWLlink
Link: http://www.owllink.org

The OWLlink is an extensible protocol defined on top of OWL 2 for the  
communication among OWL 2 aware systems intended to replace the  
outdated DIG protocol.

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

Covers all of OWL 2.

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

Supports all OWL 2 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?

Does not apply here. However, OWLlink was carefully designed to fully  
conform with the latest OWL 2 specification.

     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?

Does not apply.

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

We believe OWL2 is ready to proceed to Recommendation.
