<p class="MsoNormal"> PR #124: [oidc4vci] clarify sub value in the ID Token Issue #1426<o:p></o:p></p>
<p class="MsoNormal"> Kristina couldn't make this part of the call, so we deferred discussion on this PR<o:p></o:p></p>
<p class="MsoNormal"> PR #101: Fetching presentation definitions from a remote repository<o:p></o:p></p>
<p class="MsoNormal"> To be discussed in the SIOP call following this one<o:p></o:p></p>
<p class="MsoNormal"> Torsten added comments about the structure of the PR<o:p></o:p></p>
<p class="MsoNormal"> PR #120: Issuer Handling SIOP<o:p></o:p></p>
<p class="MsoNormal"> We discussed the "iss" and "sub" being the same for self-issued OPs<o:p></o:p></p>
<p class="MsoNormal"> They would be self-signed<o:p></o:p></p>
<p class="MsoNormal"> This blurs the distinction between self-issued and third-party OPs<o:p></o:p></p>
<p class="MsoNormal"> It's not currently possible to determine whether an OP supports SIOP or not<o:p></o:p></p>
<p class="MsoNormal"> We could introduce another metadata parameter<o:p></o:p></p>
<p class="MsoNormal"> Mike asked how to retrieve the .well-known/openid-connect metadata if the "iss" isn't a prefix for it<o:p></o:p></p>
<p class="MsoNormal"> Torsten said that for SIOP, these are decoupled<o:p></o:p></p>
<p class="MsoNormal"> Even in SIOP v1, .well-known/openid-connect metadata isn't used<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>

<p class="MsoNormal"> #1430: How to determine SIOP support?<o:p></o:p></p>
<p class="MsoNormal"> There was support for adding metadata to determine this<o:p></o:p></p>
<p class="MsoNormal"> We discussed whether to repurpose "subject_types_supported"<o:p></o:p></p>
<p class="MsoNormal"> George was against repurposing because it mixes semantics<o:p></o:p></p>
<p class="MsoNormal"> Mike would prefer a new parameter "op_types_supported" with values "third-party" and "self-issued"<o:p></o:p></p>
<p class="MsoNormal"> #1431: How to request SIOP?<o:p></o:p></p>
<p class="MsoNormal"> There currently isn't a way for an RP to request a SIOP ID Token<o:p></o:p></p>
<p class="MsoNormal"> Mike asked whether it's the RP's job to request OP types or whether it should be willing to take what it receives, leaving the choice up to the person<o:p></o:p></p>
<p class="MsoNormal"> Torsten does want RP metadata to say which types it supports<o:p></o:p></p>
<p class="MsoNormal"> Kristina said that in some use cases, RPs may care which kind of issuer they use<o:p></o:p></p>
<p class="MsoNormal"> David said the RP sends different messages to third-party and self-issued OPs<o:p></o:p></p>
<p class="MsoNormal"> George agreed with Mike that, philosophically, any kind of OP can return any kind of claim<o:p></o:p></p>
<p class="MsoNormal"> We've designed our other specifications to make this true<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Next Call<o:p></o:p></p>
<p class="MsoNormal"> The next Connect call will be on Monday, February 14, 2022 at 3pm Pacific Time<o:p></o:p></p>
