best I know of is:

http://www.w3.org/2000/10/swap/cwm.tar.gz

(although I'm not sure about literal handling)

Try it. Who knows? ;-)

I would imagine that depends which constructs of N3 are used. (I
believe in general you'd get multiple graphs + rules)

However, I believe that there

I've not spent much time with N3 proper, but it does strike me as
worthwhile exploration. Also I hate to have to contradict you, but I'm
sure you personally could develop a formal meaning for N3 (i.e. fill
in the blanks), and I've no doubt the creators of N3 would be grateful
for it to appear in the next rev of the spec.

But Michael, Phil, Peter, whoever started this thread - is there any
particular reason you need N3 over the Turtle subset (plus maybe
SPARQL's notion of named graphs)?

Cheers,
Danny.
