Hi! For my interest and understanding: What do you exactly mean by giving a name to an axiom in OWL Full? Do you mean to use a URI instead of a bNode in the RDF encoding of an axiom annotation, such as in (adapting the example from Section 2.3.1 of the RDF Mapping):

  s p o
  :spoName rdf:type owl:Axiom
  :spoName owl:subject s
  :spoName owl:predicate p
  :spoName owl:object o
  TANN(annotation_1, :spoName)
  ...
  TANN(annotation_m, :spoName)

? This would indeed be allowed in Full (though currently not reverse-mappable AFAICT; would there be any technical problems with allowing this?).

Cheers,
Michael
