Thanks for your reply. That's informative. I see that I can use
RDFParser.create() to customize the StreamRDF (using
RDFParser.create().parse(stream)).
Since I want triple processing...is extending the StreamRDFBase and overriding
the method `public void triple(Triple triple)` an option? Is it the best option?
