No, because RDF is basically a language (i.e., a system of signs [for 
denotation], syntax [subject, predicate, object roles], relation 
semantics, and statements [subject->predicate->object triples]) that 
enables encoding and decoding of information.

As Henry just stated: it isn't about syntax. It isn't about media types. 
It's about language, one that usable like any other computer language, 
but modulo the historic deficiencies associated with data definition, 
representation, and access.

If RDF had stood for "Relations Definition Framework" instead of 
"Resource Description Framework" we would have saved ourselves something 
in the region of 13+ years of distracting debates in regards to how the 
World Wide Web's basic architecture enables a variety of abstractions 
layers atop the internet:

1. document network (cloud)
2. data network (cloud)
3. semantically enhanced data network (cloud).

RDF makes possible since I wrote this all up by hand using Turtle).
