That's one way to get RDF out of a Semantic Bank, though the intent with
'export' is to use Piggy Bank to save browsing results. Another option
is to wait for SPARQL [1] to get into Sesame [2], the underlying RDF
store we use in Longwell 2.0 (which in turn underpins Piggy Bank and
Semantic Bank). We'll expose a SPARQL interface to the bank when we can
