There are words in here that I don't understand ;-) But I think I 
understand what you're getting at. And I think the approach will break 
if:-
1) The relationship schema doesn't exist in rdf form or
2) Someone starts adding relationships that don't exist in the schema
I believe there are multiple examples of both problems in the wild.
