yes nice Patrick put his CBD work available as W3C Note

even though IFBD could be harder than simple bNodes-closure, due it 
requires RDF-Schema / OWL information handy (i.e. 
owl:InverseFunctionalProperty definitions) when carrying out the CBD of 
a resource - a bit of a requirement, due that most RDF data and schema 
(their definitions) still live separately. Unless of course a service, 
software, decides to hardcode some well know IFPs like foaf:mbox, 
foaf:homepage and so on.

Anyway, such issues should not affect DAWG definition of  DESCRIBE, if 
we pretend it to return an implementation (protocol?) specific 
sub-graph containing information about the resource being described 
I.e. the same DESCRIBE request might return different results from 
different services.

return all statement reifications might also be painful...perhaps 
should that be optional or negotiable?
