How do you use RDF to model the "Dataset" created in an empty SPARQL endpoint that receives the following request? 

# (Telling http://logd.tw.rpi.edu/sparql)

INSERT {

How it is treated by currently deployed SPARQL endpoint implementations

            #     someone else's URI to describe its own partition of triples.

   rdf:containsTriples ( [ rdf:subject   tblcard:i;
