The “OWLlink Protocol” specification has been published as a W3C member submission, co-authored by experts from Clark & Parsia LLC, Creative Commons, Daimler Chrysler Research and Technology, Free University of Bozen-Bolzano, German Research Center for Artificial Intelligence (DFKI) GmbH, NTT DOCOMO, Stanford University, University of Aberdeen, Computing Science, University of Manchester, and Vrije Universiteit. The specification

defines a general, implementation-neutral protocol to access the functionalities of a reasoner acting as

an (OWLlink) server. This general mechanism is defined in term of UML; separate documents define bindings of this general protocol with different syntaxes that can be used to communicate with reasoners over HTTP. Using one of these concrete protocol bindings clients can control and query reasoners using the terms defined in the general OWLlink Structure.
