I verified my intuition that IKL covers N3 by
adding IKL output support to my N3-to-whatever translator:

v 1.13 2007/04/21 06:29:19
The superman example/test case follows.
One moderate surprise:
rdf:type gets contextualized along with superman,
since N3 has no syntax for unary relations:
Hmm. It would be better to contextualize the class name in this case
and leave rdf:type alone, I think. Since (P a) maps intuitively to
(rdf:type a P). So you do have unary relations, in effect, and
rdf:type is the encoding syntax for them.
More later.
