it is my understanding/experience that that is parsing
i.e. we get triples such as
  :WineColor rdf:type owl:Class .
  :WineColor rdfs:subClassOf :WineDescriptor .
  :WineColor owl:oneOf _:a1 .
  ...

  :White rdf:type owl:Thing .
  :Rose rdf:type owl:Thing .
  :Red rdf:type owl:Thing .

We came across the following problerm.
In the Guide the follwoing example [1] is given of "onOf":

<owl:Class rdf:ID="WineColor">
   <rdfs:subClassOf rdf:resource="#WineDescriptor"/>
   <owl:oneOf rdf:parseType="Collection">
     <owl:Thing rdf:about="#White"/>
     <owl:Thing rdf:about="#Rose"/>
     <owl:Thing rdf:about="#Red"/>
   </owl:oneOf>
</owl:Class>

Our parser has problems with this. The RDF Syntax doc appears to say
this is not the right syntax [2]. Collections should consist of node
elements, e.g.:

   <rdf:Description rdf:about="#White"/>

Correct?

A minor point is that in the wine.owl file <owl:Item> is used instaed of
<owl:Thing>.
