Could do - interesting experiment to do.  Adding new readers/writers is 
possible (but tricky currently - work-in-progress).

The fastest and most scalable way to deal with RDF is usually to print 
and load as N-triples. Compressed N-Triples is typically x8.

The pretty printing Turtle is slow because it has to analysis the model 
for structures and track all statements written.  N-triples just raw 
writes the DB.  It does not scale to very large models.

XML has proven costly to parse - N-triples is really close to just byte 

TDB loads fastest from .nt or .nt.gz (or .nq and .nq.gz).
