RDF isn't RESTFul at all. It's just a webby entity relationship model 
endowed with explicit entity relationship semantics. Thus, an RDF 
serialization isn't implicitly RESTful.

RDF based Linked Data is RESTful, in the basic sense. The basic level 
you assigned to RDF really belongs to RDF based Linked Data :-)

W3C's LDP profile effort could/should/might produce a spec for a more 
fine-grain use of RESTful patterns combined with RDF based Linked Data 
that accelerates emergence of the Web's nascent Read-Write dimension.
