Hi,
I am seeing the weirdest behaviour.
Take the following sample query:
select * where { <http://www.stalsoft.com/#BusinessEntity> ?p ?o }
The result I get back contains empty bindings ( although I am clearly
not specifying "optional" patterns ).
I asked for XML back so as to discard HTML rendering issues, and this
is what I get ( see third row ).

Aldo,
Dirty data inside Quad Store:
http://lod.openlinksw.com/describe/?url=http%3A%2F%2Fwww.stalsoft.com%2F%23BusinessEntity
.
Is there a sitemap for this source? Otherwise we'll clear out the graph
and reload via sponger.
