The object returned in output of the IdentityHubCredentialsVerifier will be changed to match the W3C Credentials.
Current implementation of the IdentityHubCredentialsVerifier such as described here
returns verified Credentials under the format of JWT claims, with the vc claim containing the actual Credential subject claims.
This approach was relevant as long as the Identity Hub was only supporting Verifiable Credentials (VC) under the format of signed JWT.
However, usually VCs are represented under the application/vc+ldp format, which uses an embedded proof instead of relying on a signed JWT.
Also, this approach is cumbersome for the policy evaluation.
It is chosen to introduce a Credential java object whose shape is compliant with the W3C Specification
and that will be returned in output of the IdentityHubCredentialsVerifier instead of the JWT claims.
A java POJO called Credential and following the W3C Specification will be introduced
in the spi package and returned in output of the IdentityHubCredentialsVerifier.
