Thanks, I'll take a look at the references you give (those I haven't
seen already).

Here's an example of what I've been working on (assuming the attachment
makes it through) - it's a set of rulebases (in RDFQL) followed by some
automated testing scripts to test the rules against the owl test cases.

I imagine that there is a class of users out there who must be doing
similar things for systems with similar capabilities. If so, I'd like to
pool our efforts if possible. I'd be happy of course if everyone decided
to use RDFQL for this purpose :-) but imagine that using something more
non-denominational (like ruleml) might be more appealing to a wider
audience.

Rgds,

Geoff
