Sorry for coming a bit late to the discussion. Here are some thoughts...

"Issuer" has the advantage that that is what is used in X509, but it only allows one
issuer, which is a disadvantage of X509 too.

Authority - seems to give the issuer more weight than might 
  be needed in some circumstances. It depends what the use 
  cases are I suppose. 

I am wondering if one could have statements in a murder case such as 

    I saw so and so at the bus station on Jan 15 2017 at 9am.
 
  Now the seer is clearly the authority on what he has seen. 

  What seems to be missing though is the relation that relates the 
claim to the signer. Could there be any number of them?

  Joe saw { JSmith do X . ... }

  DrMorgenStein states { JSmith has Measles }
  DrMorgenStein verified { JSmith has Measles }

  Joe claims { Joe foaf:knows Jim }

If all of those are ok, then perhaps there is a super-relation to all these relations.
Perhaps it is just the claims relation?

Having a relation there could be useful in that it could allow specialized applications to 
specify the type of claim more precisely?
