Not true.  Newly emerging protocols for extracting RDF from structured
data (RDFa and GRDDL) remove this barrier.  The question of what you
resolve from a URI (RDF or structured content) and what naming
convention you use is becoming a bit of a moot point (in some respects).

I see no reason why you wouldn't, when it boils down to the machination
that does the reasoning you would value (as a biological scientist) in
representing it as RDF, it is just an identifier.

This is a draconian convention for RDF URIs and one of the problems with
a verbatim interpretation of the 'Linked Data' meme (i.e., always use
HTTP - or *resolvable* - identifiers)

RDFa, GRDDL, HTML meta-data linking conventions make this separation
