Dear all,

The following is a resolution to an issue raised by Frederick
Giasson [5] with regard to the "OWL DL prune" of the SKOS
specification.  

The changes described herein will shortly become visible in
the RDF representation [1] and recorded in the SKOS Errata note
[12].

RESOLVED

That http://www.w3.org/2009/08/skos-reference/skos-owl1-dl.rdf [1]
be edited to add the triple:

     <http://www.w3.org/2004/02/skos/core>
         <http://www.w3.org/2002/07/owl#versionIRI>
             <http://www.w3.org/TR/skos-reference/skos-owl1-dl.rdf>   .

DISCUSSION

-- Section C.3 of the SKOS Reference [2] says that the
   informative (non-normative) OWL 1 DL Sub-set should be
   cited with [3], which redirects to [4].

-- The issue was originally posted on the public-esw-thes 
   list on 23 November 2010 on behalf of Frederick Giasson [5], who 
   argued that because the formal representation of the "DL prune" 
   of SKOS [6] had no version IRI, it was (fixably) breaking a 
   rule specified in the 2009 OWL2 recommendation [7]:

       If an ontology has an ontology IRI but no version IRI,
       then a different ontology with the same ontology IRI
       but no version IRI /SHOULD NOT/ exist.

-- A resolution was proposed on 23 November [8] and finalized on
   4 February 2011 on the basis of support by Mike Bergman [9],
   Rinke Hoekstra [10], and Uli Sattler [11], with no negative
   opinions or counter-proposals noted.

-- This resolution represents a "clarification" of a
   "non-normative" part of the SKOS Reference recommendation.
   The resolved change will positively enhance the usability
   of the OWL DL representation of SKOS without negatively
   affecting the conformance of documents or software.

-- The substance of this resolution will be recorded in
   the SKOS Errata note [12].
