<p class="MsoNormal"> #1400: Issuer Handling in SIOP<o:p></o:p></p>
<p class="MsoNormal"> Also see PR #120: Issuer Handling SIOP<o:p></o:p></p>
<p class="MsoNormal"> John has mixed feelings but is not opposed to the change<o:p></o:p></p>
<p class="MsoNormal"> Kristina said that this generalizes "iss" to no longer always be an https URI<o:p></o:p></p>
<p class="MsoNormal"> Kristina said that we may want to separately convey trust in a wallet, perhaps through an attestation claim<o:p></o:p></p>
<p class="MsoNormal"> She said that in the mDL space, there's a lot of emphasis on determining trust in the wallet<o:p></o:p></p>
<p class="MsoNormal"> John noted that Microsoft, Google, and Apple are likely to have different attestation formats<o:p></o:p></p>
<p class="MsoNormal"> John said that the issuer isn't the Wallet<o:p></o:p></p>
<p class="MsoNormal"> Kristina plans to write a PR adding an attestation claim<o:p></o:p></p>
<p class="MsoNormal"> John and George talked about the differences in trusting apps, software providers, wallets, and issuers<o:p></o:p></p>
<p class="MsoNormal"> And the relationship to trust frameworks<o:p></o:p></p>
<p class="MsoNormal"> Kristina asked George to write a comment on the separation between IdP software and the entity<o:p></o:p></p>
<p class="MsoNormal"> John is concerned that every issuer will have their own wallet<o:p></o:p></p>
<p class="MsoNormal"> There was no opposition on the call to merging PR #120<o:p></o:p></p>
<p class="MsoNormal"> #1429: Replace JWK Thumbprint URI with JWK URI<o:p></o:p></p>
<p class="MsoNormal"> Mike summarized the discussions so far for John, etc.<o:p></o:p></p>
<p class="MsoNormal"> He talked about "sub" needing to be stable and of modest size<o:p></o:p></p>
<p class="MsoNormal"> John said that large "sub" values will randomly blow up RPs<o:p></o:p></p>
<p class="MsoNormal"> David said that RPs could instead compute its own stable identifier<o:p></o:p></p>
<p class="MsoNormal"> John said that RPs expect something stable for the subject<o:p></o:p></p>
<p class="MsoNormal"> John observed that JWK URI is sort of equivalent to having a self-contained DID in the URI<o:p></o:p></p>
<p class="MsoNormal"> Such as did:key<o:p></o:p></p>
<p class="MsoNormal"> John said that people could think of this a simplified self-encoded DID<o:p></o:p></p>
<p class="MsoNormal"> Kristina said that it's different from did:key because did:key has DID Doc<o:p></o:p></p>
<p class="MsoNormal"> She's concerned about adding a third type because less functionality is more<o:p></o:p></p>
<p class="MsoNormal"> John said that if we can encode the key as a DID, we don't need JWK URI<o:p></o:p></p>
<p class="MsoNormal"> David Chadwick is happy to close this in favor of PR #127<o:p></o:p></p>

<p class="MsoNormal"> Kristina will file an issue questioning the need for a third identifier type and link to this PR<o:p></o:p></p>
<p class="MsoNormal"> John isn't in favor of a third identifier type<o:p></o:p></p>
