<p class="MsoNormal">Benjamin Zapilko and I are currently reviewing the open issues of Disco. The goal is to resolve the issues and to prepare Disco finally for publication.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now I have questions on two issues:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">--<o:p></o:p></p>
<p class="MsoNormal">There is an issue on how to describe missing values for a numeric response domain.<o:p></o:p></p>
<p class="MsoNormal">Details and my comment see at <a href="https://github.com/linked-statistics/disco-spec/issues/130">
https://github.com/linked-statistics/disco-spec/issues/130</a>. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My question:<o:p></o:p></p>
<p class="MsoNormal">Is there really missing something in Disco? I don’t have the impression. But maybe I misunderstood something.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">--<o:p></o:p></p>
<p class="MsoNormal">The other issue is that the conceptual variable of DDI 3.2 does not exist in Disco.
<o:p></o:p></p>
<p class="MsoNormal">The hierarchy is only Variable, RepresentedVariable, skos:Concept.<o:p></o:p></p>
<p class="MsoNormal">Details and my comment see at <a href="https://github.com/linked-statistics/disco-spec/issues/226">
https://github.com/linked-statistics/disco-spec/issues/226</a>. <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The whole approach of Disco is to focus on a simple subset of DDI Codebook and DDI Lifecycle for Discovery purposes. It is not a 1:1 representation.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My question:<o:p></o:p></p>
<p class="MsoNormal">Is it really important to be able to search for the ConceptualVariable in addition to Variable, RepresentedVariable, and Concept.<o:p></o:p></p>
<p class="MsoNormal">Is this addition really worth it? This might result in some work for Disco.<o:p></o:p></p>
<p class="MsoNormal">Any thoughts would be helpful.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
