You can mix and match ontologies, Ontologies do not have any implication
as to syntax. However, the presence of a specific ontology in an RDF
document (regardless of serialization) does have very significant
functionality implications, and their presence is an indication
(instruction even) of how the specific RDF document should be
interpreted by a machine in a given context.

See ACL, diff, and cert/foaf when used with FOAF+SSL. In all of these
cases the lack of a specific ontology has very serious implications.

As Larry said: 'An "Internet Media Type" is more than a definition of
syntax -- it's is an indication of intent, by the sender, for how the
sender wishes the receiver to interpret the content being sent.'

Do the aforementioned ontologies don't come under that banner..?

I'm quite sure that what I'm looking for in this scenario is certainly
not SPARQL or even SPARUL, or the forthcoming "SPARQL 1.1 Uniform HTTP
Protocol for Managing RDF Graphs", however nice they may be.
