[Openid-specs-ab] Issue #1229: Adoption of the "OpenID Connect for W3C Verifiable Credential Objects" (openid/connect)

Mon May 10 16:19:10 UTC 2021

One issue is that this is NOTHING about credentials at all, this needs to be removed entirely as we should not be dealing at that level.

We do not need to provide definitions as they already exist in the W3C VC Data Model Recommendation, so we can simply reference them. They are:

claim

An assertion made about a subject <https://www.w3.org/TR/vc-data-model/#dfn-subjects> . 

credential

A set of one or more claims <https://www.w3.org/TR/vc-data-model/#dfn-claims>  made by an issuer <https://www.w3.org/TR/vc-data-model/#dfn-issuers> .

A verifiable credential is a tamper-evident credential that has authorship that can be cryptographically verified. 

You will note that the W3C recommendation does not say anything about what the assertion may be, but if you look it up in a dictionary you will get something like

Assertion - a positive statement or declaration, often without support or reason 

Please tell me what is unclear about the above

Kind regards

David

And I find the lack of clarity to be extremely rude and disrespectful of any sort of meaningful conversation about the issues. If you have a better definition of claim, please let us hear it.

thx ..Tom (mobile)

This is another example of an extremely rude and disrespectful tone by the same person: 

"I want clarity of language. Right now we just have a claim = some crap and credential = a pile of crap."

Thank you, Nat.

As promised, I wanted to outline the relationship between "OpenID Connect for W3C Verifiable Credential Objects" (OIDC4VCO) draft and other existing drafts. (point 2 in this issue) 

※ Note that there was a proposal to rename the draft  "OpenID Connect for W3C Verifiable Presentations", but I will use OIDC4VCO abbreviation for now.

*	Relationship with OpenID Connect Core: OIDC4VCO uses mechanisms already defined in OIDC Core, and does not introduce any breaking changes.
*	Relationship with SIOP V2 draft: SIOP V2 draft will refer to the OIDC4VCO draft wrt how W3C verifiable presentations (VPs) can be transported using SIOP model, since OIDC4VCO draft defines a generic way how W3C VPs can be used with various OIDC flows including SIOP V2.
*	Relationship with Claims Aggregation draft (and Credential Provider draft once contributed): these drafts will be used by the OP to receive credentials from the Claims Provider, so that the OP will be able to present received credentials to the RP using OIDC4VCO draft. These drafts should be aligned as much as possible.
*	Relationship with DIF Presentation Exchange (PE) draft: DIF PE draft could be used as part of the request syntax in OIDC4VCO draf, which can be discussed once OIDC4VCO draft is adopted. DIF PE is a query language that is protocol agnostic, and it does not replace OIDC4VCO draft.

This is an initial summary and additional input from the editors/working group is very welcome.

A work item to enable transporting W3C VPs using OpenID Connect, will most likely not be successful outside OpenID Foundation AB/C Working Group, because that is where the collective OpenID Connect expertise resides. 

Best,

Kristina

Some concerns were expressed by a few WG members. 

This ticket is to give an opportunity for those members to express their concerns and proposers to reply to them. 

There are a few criteria for non-adoption of documents: namely

1. If the draft does not fall into the scope of the WG. 
2. If the draft is overlapping with existing drafts, the technical content should be raised as an issue and eventually result in PR rather than starting a new draft. 

    1. NOTE: A non-overlapping portion can be made as an independent document so proposers should consider creating such. 

3. If there is a legal or reputational risk for the OIDF in adopting the document. \(The board may intervene on this ground.\) 

If the issues are only on the technical nature of the proposed draft that does not fall into the above criteria, then, it should be dealt with during and after the adoption of the document.
