Re: FYI >> DHS W3C VC/DID Implementation Profile: Credential Data Model Representation Syntax & Proof Format

Anil, this is fantastic, thank you!

I was pleasantly surprised to see the item “SHOULD leverage objects instead
of strings to refer to Issuers and Holders”!
We’ve been using issuer objects (which include issuer name & logo) in the
VC-Edu task force, and I was planning to campaign for supporting this
natively in the VC 2.0 data model. So it’s really great to see
support/confirmation for this.
