Future Calls

To Dos:
- Request from Stephen Curran -- I'd like to go through the
presentation
section of the spec to convert the specific implementation calls (e.g.indy_prover_...
and the like) into content to be more about the data objects passed into AnonCreds/returned from AnonCreds for processing events. - Ankur to add paragraph about philosophy of the AnonCreds API, styles
- Review the Issuing and Presentation sections to exclude Legacy Indy impacts, and to formalize the Abstract API for writing/reading published objects
- Cred Def Generation + PRIVATE_CRED_DEF -- non revocation, and plus revocation
- Revocation data elements -- definition
- Normative/Non-normative references
- Collect from documents mentioned below (under action items) and from previous meeting
Action items
- Suggestion made and supported that the group request to provide a presentation about AnonCreds to the W3C VC Working Group about the formatting of AnonCreds verifiable credential and presentation in W3C format and the processing implied.
- Issue -- should "encoded" generation be handled by the Issuer or within AnonCreds?
- Formalize the encoding in the specification
- Transition to "encoding in AnonCreds" ASAP
- Links to be referenced in the spec and used where needed:
- From Artur Philipp : Issue about raw/encoded values used in AnonCreds https://jira.hyperledger.org/browse/IS-786
- Latex in Spec-Up / (Re)Discovery of AnonCreds Protocols paper from Mike Lodder, Brent Zundel. There is a full latex version of the document -- that document uses images to get the calculations into the text.
