https://bitbucket.org/openid/connect/issues?status=new&status=open&component=SIOP</a><o:p></o:p></p>
<p class="MsoNormal"> #1239: We should stop using "SIOP" as an umbrella term and instead talk about individual features.<o:p></o:p></p>
<p class="MsoNormal"> We continued discussing this issue, which we'd started on the previous SIOP call<o:p></o:p></p>
<p class="MsoNormal"> Dmitri said that self-issued.me is a protocol switch<o:p></o:p></p>
<p class="MsoNormal"> Mike said that part of that switch is that a self-issued OP can't host any metadata<o:p></o:p></p>
<p class="MsoNormal"> Mike said that a conceptual difference is that with SIOP, you host your own claims, rather than a third party<o:p></o:p></p>
<p class="MsoNormal"> That's a control difference - not a protocol difference<o:p></o:p></p>
<p class="MsoNormal"> But it's part of why SIOP is interesting to User-Centric Identity / SSI advocates<o:p></o:p></p>
<p class="MsoNormal"> Pam proposed that we create a document with shared editing to work on this<o:p></o:p></p>
<p class="MsoNormal"> DW will create a HackMD document for us to work on together<o:p></o:p></p>
<p class="MsoNormal"> He requests that people mostly make comments, rather than directly making edits<o:p></o:p></p>
<p class="MsoNormal"> Another difference is how the key is retrieved<o:p></o:p></p>
<p class="MsoNormal"> 3rd party OPs use the hosted JWK Set<o:p></o:p></p>
<p class="MsoNormal"> SIOP V1 uses the sub_jwk<o:p></o:p></p>
<p class="MsoNormal"> SIOP V2 enables a level of indirection, such was using a DID or an Entity Statement<o:p></o:p></p>
<p class="MsoNormal"> About "Non-identified SIOP instance", Kristina said that that is a benefit, as it prevents correlation<o:p></o:p></p>
<p class="MsoNormal"> There is no identifier for a particular SIOP instance<o:p></o:p></p>
<p class="MsoNormal"> DW noted that his list in the issue is a list of what SIOP V1 does - not all the properties that we might want<o:p></o:p></p>
<p class="MsoNormal"> This issue is related to #1209: For migration, should support multiple subjects at once in portable identifiers cases<o:p></o:p></p>
<p class="MsoNormal"> On "Reduced back-channel accessibility", the problem is that there's no place to host Web Endpoints<o:p></o:p></p>
<p class="MsoNormal"> On "Implicit-only interactions", Mike said that only Implicit flows are possible because there's no place to host a Token Endpoint<o:p></o:p></p>
<p class="MsoNormal"> Mike suggested adding a point "No place to host Web Endpoints", from which some of the others derive<o:p></o:p></p>
<p class="MsoNormal"> "Just-in-time Client Registration" is another consequence of "No place to host Web Endpoints"<o:p></o:p></p>
<p class="MsoNormal"> Pam asked about the relationship between Dynamic Client Registration and Ad-Hoc Trust<o:p></o:p></p>
<p class="MsoNormal"> For instance, is the dynamic registration state remembered or is trust re-established on each use?<o:p></o:p></p>
<p class="MsoNormal"> DW said that registrations are remembered so that pairwise identifiers can be maintained<o:p></o:p></p>
<p class="MsoNormal"> DW wondered how Automatic Registration deals with changes in client properties<o:p></o:p></p>
<p class="MsoNormal"> Mike said this would be a fabulous time for people to review the OpenID Connect Federation spec to see if it's clear on these points<o:p></o:p></p>
<p class="MsoNormal"> DW espoused the role of Trust Frameworks to profile specifications and represent trust in entities<o:p></o:p></p>
<p class="MsoNormal"> Kristina asked Dmitri about Solid's use of something like Entity Statements<o:p></o:p></p>
<p class="MsoNormal"> Dmitri said that Solid's Client IDs are URLs that you resolve to retrieve metadata<o:p></o:p></p>
<p class="MsoNormal"> Mike thanked Dmitri for the parallel data point<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Credential Provider Draft<o:p></o:p></p>
<p class="MsoNormal"> Tobias contributed the Credential Provider Draft<o:p></o:p></p>
