How do we get processors to recognize methods like "invertProgram"? Is there
some way of getting from:-
[A, isLeftOf, B] to [B, isRightOf, A]
Or in other words, what is the RDF Schema way of saying [You, do!, invert]
so that when we invent this property, it automatically finds the reverse of
all of our triples? This is really great, because although:-

     <not>[A, isLeftOf, B]</not> != [B, is RightOf, A]

You could say:-
     if <not>[A, isLeftOf, B]</not> != [B, is RightOf, A]
     then [A, isLeftOf, B] = [B, is RightOf, A]
     and also [<not>A</not>, <not>isLeftOf</not>, <not>B</not>] = [B, is
RightOf, A]!

Which is exactly what I was looking for, and because the assertions are the
same that implies that there must *be* a way of implying "not" by simply
using rdfs...am I right?

> Don't you think if  [we, do!, it], we could get a little action?

You could write a novel in triples :-) I think it should definitely be done,
(actually I'd be suprised if it hasn't been done already).
