Discussion Items
- May I ask if anyone here has experimented with signing PAdES (PDF Advanced Electronic Signature) with KERI?
  - No one explicitly but a good route for adoption
    - How would you go about integration into acrobat etc
    - currently signed with x509
- Graduated disclosure
  - Append to extend
    - chain additional material to existing acdcs
    - no dynamically changing of existing material
    - hashes further up the chain remain verifiable
    - metadata acdc would be the first step in a graduated disclosure
      - Eg you're showing someone more personal information
        here are my terms regarding the presentation
        the disclosee they sign their metadata acdc with a blinded hash of the attribute block and the rules of the disclosure
- IIW "thoughts"
