[RDF] Queries, filters, context, trust, and more.., part 2

[Jonas Liljegren]

Here are a couple of things to add to the feature list: Versioning,
authorization and trust.

Let's say that the person has a lot of phone numbers.  

 - A person could say that the number has changed.  The request should
   retrieve the latest number rather than the old incorrect number.

 - If the person stating that the number has changed is untrusted, we
   should instead retreive the previous number.

 - If the previous number is restricted, we would have to accept the
   later untrusted number.  But we could also try to convince the
   service that we are authorized to recieve the restricted
   information.
