Hi Daniel, I'm not sure anyone has published a draft yet, but given that there is a draft for SD-CWT I wouldn't be surprised if SD-CWT VC appears at some point. With that in mind, has there been any discussion on having an encoding-agnostic specification of this metadata, rather than JSON specific?
