Kim, as promised, here is a link to the latest version of the InterCredential ARM tutorial...

Internet Credential (InterCredential) Architecture Reference Model 0.67
https://www.youtube.com/watch?v=PHz5IrbvTsY&list=PLU-rWqHm5p44AsU5GLsc1bHC7P8zolAAf&index=5

This tutorial elaborates on several topics:

  *   4 InterCredential examples slide added (slide 32)
  *   4-Corner InterCredential Interoperability Model (Intercredential-4C) (slide 33)
  *   DIDComm Agent Logical Composition (slide 45)
  *   Internet Credential Composition Model (InterCredential Software Pipeline) (slide 54)

This following is the best resource available today...

Internet Credential (InterCredential) Architecture Reference Model 0.65
https://youtu.be/A8VzFwbDTLM

Version 0.66 will include a detailed application of DIDComm Agent logical composition to the 4-Corner Credential Interoperability Model. Likely available tomorrow.
(I'm inbound from Merida to Houston to Calgary to NYC over the next 24 hours.)

The spec text is a work-in-progress.

I searched for InterCredential spec but couldn't find it. I found this web 7.0 reference but it's not clear it's what you're talking about: https://dl.acm.org/doi/fullHtml/10.1145/3184558.3190666

Pointers to specs please?

Rather than engage in endless debate, it's easier/more expedient to embrace, by reference, the W3C VC2 specification as a sub-specification of the InterCredential spec ...an embrace-and-extend model ...and let the decentralized systems developer marketplace decide.



After the inclusion of the 4-Corner Credential Interoperability Model into the InterCredential ARM, the W3C VC2 spec becomes a niche layer/specification.  See the green box in the diagram below.

Thank you, Nate -- that was wonderfully written! I found myself nodding in agreement as I read through your response.



Michael, does Nate get it? He seems to have addressed all of your questions/statements?
