Thanks, that's just the sort of thing I meant. Do you have any
statistics on which of the owl test cases pass and which fail with these
rules? I'll compare them against what I've come up with.

Perhaps the syntax is less important than the content. It would be
interesting to come up with a common set of rules that could be
implemented in n3/euler, rdfql, and perhaps prolog (I think whatever
subset - formal or not - of owl that is defined by those rules will be
as prevalent as any other.) Undoubtedly we could each then extend the
common set based upon specific features of our languages to get as close
as possible to full owl.

I'll start by publishing my rules on our site, numbering them for
reference and cross-referencing them with your numbered rules.

I sent an example as an attachment in my response to Harold Boley - I'll
resend if the attachment doesn't make it through.
