Hi James,
It's been tested with Firefox (3.5), Safari (4) and IE (7 & 8) (in
which it runs dreadfully slowly), but it hasn't been with Opera. (In
fact, I did so just now and it's failing some of the tests, mostly to
do with XML serialisation; I'll look into it.)
If you checkout trunk (
http://rdfquery.googlecode.com/svn/trunk/) you
can run the tests by opening tests/jquery.alltests.html in the browser
you want to test.
Hope that helps,
Jeni
