Presumably this will remain a purely syntactic mapping and the comment 
in your "Next Steps for OWL" paper [1]:

    "A triple syntax is being provided for OWL 1.1, syntactically
    compatible with the triple syntax for OWL DL. However, for the above
    reasons, this syntax could not be given a meaning compatible with the
    RDF meaning for triples ..."

will still apply?
