You may be interested in my paper to the LAPIS workshop on ESWC:
http://folk.uio.no/kjekje/2012/hypermedia-rdf.pdf
with slides:
http://folk.uio.no/kjekje/2012/lapis2012.xhtml

In there, I advocate that timbl's requirement would be satisfied in a 
RESTful manner if everyone linked to a VoID description (like the VoIDists 
already responded), or failing that, adding these two triples to every 
description, e.g.

<> void:inDataset [ void:sparqlEndpoint </sparql> ] .

My own implementation does this now by default:
https://metacpan.org/module/RDF::LinkedData
as can be seen here:
