Future Calls

To Dos:
- Backwards Compatibility
- PRs in (#82, #105) that seem to change public data structures – ones that are handled outside of AnonCreds and/or by two or more participants (issuer, holder, verifier)
- We want to retain compatibility with existing data – credentials that have been issued and the published AnonCreds objects on which they rely.
- That extends to business logic – e.g. the handling of the objects not just by AnonCreds, AnonCreds Methods and Aries Frameworks, but also by business applications built on Aries.
- Suggestion:
- Include in the specification a statement about backward compatibility
- Perhaps this is what Ankur had planned to do?
- Formalize what data structures will be expected by AnonCreds
- This is being done throughout the specification and verified against the current implementation.
- As needed support sending and receiving data in "old" and "new" formats, but (for now) always sending "old" formats.
- TBD if there are any such cases.
- Include in the specification a statement about backward compatibility
- 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
- Normative/Non-normative references
- Collect from documents mentioned below (under action items) and from previous meeting
Action items
- Request from Stephen Curran -- I'd like to go through the
presentationsection 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. - 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:
