For sure, JCR repository is a conected digraph with special  vertex  
(the root), RDF simply is a digraph (a directed graph)
which is a more general concept.

Well although we think RDF would be very profitable and powerfull 
feature we also think it's better to release
the first stable jsr-170 while using Jackrabbit as testbed. RDF is often 
misused and there is not very much
well undertanding about it, so it could be a burden to general acceptance.
