<p class="MsoNormal"> David is asking what the preferred way is<o:p></o:p></p>
<p class="MsoNormal"> Related to issue #1593: [has-PR] Ordering claims in OP Metadata<o:p></o:p></p>
<p class="MsoNormal"> Mike and Jeremie are in favor of the third option - a parameter that is an array<o:p></o:p></p>
<p class="MsoNormal"> PR #241: Add schema to OP Metadata (Issue #1578)<o:p></o:p></p>
<p class="MsoNormal"> David said that there isn't a one-to-one mapping between credential types and schemas<o:p></o:p></p>
<p class="MsoNormal"> He said that knowing the presentation schema may be even more useful than knowing the credential schema<o:p></o:p></p>
<p class="MsoNormal"> Me made a distinction between verification and validation<o:p></o:p></p>
<p class="MsoNormal"> Kristina asked if we want to publish schemas for issued credentials<o:p></o:p></p>
<p class="MsoNormal"> Mike asked if we have even decided what schema language to use, should we want to do so<o:p></o:p></p>
<p class="MsoNormal"> David Chadwick said that the VC WG has a schema type parameter to declare what schema language you're using<o:p></o:p></p>

<p class="MsoNormal"> David Chadwick said that this addresses issues #1566, #1628, and #1592<o:p></o:p></p>
<p class="MsoNormal"> Oliver said that there are several different things that we are calling types<o:p></o:p></p>
<p class="MsoNormal"> David talked about local names versus global names<o:p></o:p></p>
<p class="MsoNormal"> David said that the VC WG takes the position that a credential should be independent of the proof attached to it<o:p></o:p></p>
<p class="MsoNormal"> Kristina distinguished between credential types and credential formats<o:p></o:p></p>
<p class="MsoNormal"> The credential type is an abstract identifier, whereas the credential format identifies a data structure<o:p></o:p></p>
<p class="MsoNormal"> Oliver doesn't see a normative definition of credential_type<o:p></o:p></p>
<p class="MsoNormal"> David Chadwick would prefer that we use statements like "credential_type":"University Degree"<o:p></o:p></p>
<p class="MsoNormal"> David gave the example have having University Degree credentials for degrees in Chemistry and Philosophy<o:p></o:p></p>
