But please note that my "second recommendation" just targeted on this. While
in my "first recommendation" I suggested to use "owl:Class" in all /new/ OWL
ontologies, I also suggested that the OWL reasoner developers should change
their reasoners to silently substitute occurrences of "rdfs:Class" by
"owl:Class" before reasoning starts. Technically this is very simple: Just
look up all triples containing "rdfs:Class" and substitute them by the same
triples containing "owl:Class" instead. This is a matter of a few lines of
code with JENA, for example.
