<- You have guys have me really confused. Are you trying to find a way to

I think the confusion stems from the fact that 'if' and 'then' (/'else') are
commonly used in both declarative and imperative computer languages. In the
declarative context if...then... goes right back to the basic connectives of
propositional logic, where one can say if <something> then <something
else> - a relationship is stated, there is no processing involved. RDF is a
declarative language (a representation language, whether or not you call it
a programming language is probably irrelevant), so surely this is the
appropriate context here.
