Today the OWLlink Working Group announces the publication of the final OWLlink 
protocol specification <http://www.owlink.org>. The OWLlink interface provides an 
implementation-neutral mechanism for communication between OWL 2 components. It is a 
refinement of the outdated DIG protocol, fully aligned with the just released Web 
Ontology Language OWL 2. A key feature of OWLlink is its extensibility w.r.t the 
language and its flexibility in supporting multiple transfer protocols.

The OWLlink core specification consists of the following 3 parts:

o Structural Specification <http://www.owllink.org/owllink/>
o HTTP/XML Binding <http://www.owllink.org/owllink-httpxml>
o HTTP/Functional Binding <http://www.owllink.org/owllink-httpfunctional>

OWLlink has already been implemented in a set of tools:

o The RacerPro Reasoner v2.0 <http://www.racer-systems.com/>
o The Prolog OWL 2 API Thea <http://wiki.github.com/vangelisv/thea>
o An OWLAPI connector <http://owllink-owlapi.sourceforge.net/> that allows:
  - OWLAPI clients to access OWLlink aware reasoners and
  - OWLAPI reasoners to be accessed via OWLlink

Best Regards,
The OWLlink Working Group
