<li>David C. suggested changing verifiable_presentations to presentation_definition.</li><li>Torsten pointed out that that will not work with vp_token request syntax which directly embeds input_descriptors in vp_token clam<br>
</li><li>Jeremie suggested a simple way to support both needs by simply using the presentation_definition property within the verifiable_presentations claim request.</li><li>Torsten alerady created a PR: <span style="background-color:rgb(255,255,255); display:inline!important"><a href="https://bitbucket.org/openid/connect/pull-requests/23/introduce-presentation_definition-element" id="LPlnk878932">https://bitbucket.org/openid/connect/pull-requests/23/introduce-presentation_definition-element</a></span></li><li style="display:block"><br>

<li>OIDC4VP draft puts format property from the presentatio exchange request into the registration metadata, according to the philosophy of OpenID Connect - while keeping the schema defined in the PE spec as Torsten pointed out. </li><li>We discussed the possibility of putting format property in the request and be compliant with the PE specification, but unanimously agreed that to keep the current choice. The reason is - format element is not credential or presentation specific, it is a
static information that applies to all the credentials and presentations that the client requests and OP can handle. In OpenID Connect, Server and Client metadata is typically where such information is being handled. </li><li>David C. said that this choice is consistent to his implementation experience.</li><li>Kristina asked how can formats of both VP and VC be specified.</li><li>Stephane pointed out that in some issues we preserve PE syntax, while in some issues we prioritize OpenID Connect philosophy.</li><li style="display:block"><br>

<li>Passing by reference PE request object in the request URL: <a href="https://bitbucket.org/openid/connect/issues/1238/requesting-verifiable-presentation" style="margin:0px">https://bitbucket.org/openid/connect/issues/1238/requesting-verifiable-presentation</a></li><ul>
<li>We discussed that passing policy, aka entire presentation exchange request structure, by reference, where a URI is trusted because it belongs to a trust framework can be "readily usable for policy/framework use cases with SIOP and presentations where there
is a larger agreement in place on the authority of the hosted request objects". <span style="background-color:rgb(255,255,255); display:inline!important">Jeremie already made a comment to the issue that summarizes the discussion really well.<span> </span></span></li></ul>

<li><span class="x_x_markuclqdxk1g">SIOP</span> V2</li><ul>
<li>We did not have time to go through these issues. Kristina encouraged to read and comment on the two following issues in particular:</li><ul>
<li>An issue back from 2018: <a href="https://bitbucket.org/openid/connect/issues/1027/write-a-self-issued-idp-si-idp-best" id="LPlnk">https://bitbucket.org/openid/connect/issues/1027/write-a-self-issued-idp-si-idp-best</a></li><li>Progress on <span class="x_x_markuclqdxk1g">SIOP</span> properties: <a href="https://bitbucket.org/openid/connect/issues/1239/we-should-stop-using-siop-as-an-umbrella" id="LPlnk">https://bitbucket.org/openid/connect/issues/1239/we-should-stop-using-siop-as-an-umbrella</a></li></ul>
