Verifiable Credentials Overview
This is a new doc (13 June 2024) that seems to serve as an introductory / big picture primer on the subject.

SD-JWT-based Verifiable Credentials (SD-JWT VC)
Selective Disclosure (4 Mar 2024 version)
https://datatracker.ietf.org/doc/html/draft-ietf-oauth-sd-jwt-vc-03
This draft clarifies that declaring a vct (Verifiable Credential Type) is mandatory in SD-JWT context but also that the actual vct definitions are out of scope of the draft. People within their own ecosystems should come up with those.
Our idea is to create eduPersonIdentityCredental , voPersonCredential, etc.
VC JSON Schema Specifications
18 December 2023
People now feel that the JSONs should be checked against a schema, just like XML schemas. These are the JSON Schmas, and the draft is about VC validation against schemas

eduPerson
The good ol' eduPerson spec

VC data model

OpenBadges v3 (Now a W3C VC)
https://1edtech.github.io/openbadges-specification/ob_v3p0.html#credentialsubject
Here we have a simple credentialsubject declaration at B.1.22
This is also featured here: https://www.w3.org/TR/vc-data-model-2.0/#credential-subject
In the examples the CredentialSubject is extended quite random ways (degree and spouse)

Use Case - OJS ORCID 
review credit plugin
https://github.com/pkp/orcidProfile/issues/181
- Lifelong learning/student mobility
- SNI
- MMS authorization - short expiration
- reviewer credit
Question: Expiration - quality - RAF-like stuff
Nils's suggestion: Base Identity education credential set == personalized
- express: how was the data LoA verfied etc
- freshness
Two outcomes
- spec on eduPerson, voPerson expression
- implementation guide
