Hi, that's a great question. Actually, there is no definition of what a
verifier does except verifying VC/VP data integrity by re-computing a proof
value.

I've not found anything related to a subject evaluation, i.e. how to
process claims about a subject.  One way could be to use SPARQL to run a
query or queries on the subject after a successful proof value
verification, but that's quite a big cannon to get answers on simple
questions like  "Is the subject member of XY".

Does anyone work on automated claims verification/extraction?

Best,
Filip

Any tools to date that just fetches the N-Quads and verifies OK?
