for our data is not to publish valuable data on the web at all, and
that's a pity.

I hope this is not too off-topic for a mailing list entitled 'linking

A question that will surely arise in many places when more people get to

know about the linked data initiative and the growing infrastructure of 
linked open data is: how can these principles be applied to
data that might not / only partially be open to the public web? People
soon try to develop practices for selectively protecting parts of their 
linked data with fine-grained access rights. Could simple HTTP 
authentication be useful for linked data? How does authentication work

vocabularies to represent access rights? Should such vocabularies be 

Is there any ongoing work on defining such practices (or even 'best
