Here is an example where nesting would IMHO be at least a "nice to have" feature: When mapping the following OWL axiom Class( C partial restriction(p allValuesFrom(D)) ) to RDF, here demonstrated in Turtle: :C a owl:Class ; rdfs:subClassOf [ a owl:Restriction ; owl:onProperty :p ; owl:allValuesFrom :D ] . The unnested case would be: :C a owl:Class ; rdfs:subClassOf _:1 . _:1 a owl:Restriction ; owl:onProperty :p ; owl:allValuesFrom :D . Somewhat more verbose, and I have to introduce an otherwise redundant name for the bNode. This is not so nice (but of course this is not a critical thing). Cheers, Michael -- Dipl.-Inform.
