clarification: it would be a way to publish information on the web  
about your trust in signatures.
But it would not be something to use SPARQL graph notation to query for.

Graph notation is a way to make statements about statements, to track  
where statements are coming from etc.
It is really important to understand this 4th element in the triple  
spaces.

With triples <Subect relation Object> you can describe the world. To  
describe what others think, or how things could
be you need quads:

  <Subject relation Object World>

Where you can think of World as a referent to the set of possible  
worlds in which the statement <Subject Relation Object> is true.

It's the difference between believing that the cat is fed, and saying  
Jane believes that the cat is fed.
It is what allows you to say that Lois Lane loves Superman, but that  
Lois Lane does not believe she loves Clark Kent.

:LoisLane :believes { :ll loves SuperMan ;
                           dislikes ClarkKent .
                     } .

even though

SuperMan = ClarkKent .

You cannot deduce that Lois Lane is believing a contradiction. You  
cannot because Lois Lane does not believe
Superman = ClarKent .

Anyway see my article on Beatnik to see a little how one has to deal  
with the situation, if one wants to be able to have defeasible  
reasoning.
