Yes, that's how the first version of glean.py worked.

But more recent versions support "following your nose" thru
profile/namespace documents, GRDDLing those, and looking
for statements of the form
  profile dataview:profileTransformation ?XFORM.

so there's some non-trivial RDF-level processing going on. I thought
about doing that with XSLT, but then thought better of it.
