I would rather the UC&R document did not try to motivate technical solutions but 
  explained use cases and requirements.  I think it does that.

I don't think we can address any trust issues - the impact on query is just a 
small part of an overall approach.  The approach needs to be in place first 
before we can design to it.

As Matthias is revealing the source of triples, to Johanna and others, he's 
going to have to use URIs if source information is to be returned in query results.



A simple example might have been newsfeeds - needing to track which newsfeed 
says what is important.  Especially near elections.
