<li>dcterms.spatial</li>

<li>
|
|
<p>Identify and propose the next phase of CGSpace fields to migrate:</p>
|
|
<ul>
|
|
<li>dc.title.jtitle → cg.title.journal</li>
|
|
<li>dc.identifier.status → cg.identifier.status</li>
|
|
<li>dc.river.basin → cg.river.basin</li>

<li>dc.Species → cg.species</li>

<li>dc.targetaudience → cg.targetaudience</li>

<li>dc.fulltextstatus → cg.fulltextstatus</li>
|

<li>dc.editon → cg.edition</li>
|
|
<li>dc.isijournal → cg.isijournal</li>
|
|
</ul>
|

</li>
|

<li>
|

<p>Start a test rebase of the <code>5_x-prod</code> branch on top of the <code>dspace-5.5</code> tag</p>
|
|
</li>
|
|
<li>
|
|
<p>There were a handful of conflicts that I didn’t understand</p>

<p>After completing the rebase I tried to build with the module versions Atmire had indicated as being 5.5 ready but I got this error:</p>

<li>Looks like the issue that Abenet was having a few days ago with “Connection Reset” in Firefox might be due to a Firefox 46 issue: <a href="https://bugzilla.mozilla.org/show_bug.cgi?id=1268775">https://bugzilla.mozilla.org/show_bug.cgi?id=1268775</a></li>
|
|
<li>I finally found a copy of the latest CG Core metadata guidelines and it looks like we can add a few more fields to our next migration:
|
|
<ul>
|
|
<li>dc.rplace.region → cg.coverage.region</li>
|
|
<li>dc.cplace.country → cg.coverage.country</li>
|
|
</ul>
|
|
</li>
|
|
<li>Questions for CG people:
|
|
<ul>
|
|
<li>Our <code>dc.place</code> and <code>dc.srplace.subregion</code> could both map to <code>cg.coverage.admin-unit</code>?</li>
|
|
<li>Should we use <code>dc.contributor.crp</code> or <code>cg.contributor.crp</code> for the CRP (ours is <code>dc.crsubject.crpsubject</code>)?</li>
|
|
<li>Our <code>dc.contributor.affiliation</code> and <code>dc.contributor.corporate</code> could both map to <code>dc.contributor</code> and possibly <code>dc.contributor.center</code> depending on if it’s a CG center or not</li>
|
|
<li><code>dc.title.jtitle</code> could either map to <code>dc.publisher</code> or <code>dc.source</code> depending on how you read things</li>
|
|
</ul>
|
|
</li>
|
|
<li>Found ~200 messed up CIAT values in <code>dc.publisher</code>:</li>

<li>More theorizing about CGcore</li>

<li>dc.place → cg.place</li>

|
|
<li><code>dc.place</code> is our own field, so it’s easy to move</li>

<li>I’ve removed <code>dc.title.jtitle</code> from the list for now because there’s no use moving it out of DC until we know where it will go (see discussion yesterday)</li>

<li>Work on 707 CCAFS records</li>

<li>They have thumbnails on Flickr and elsewhere</li>

<li>In OpenRefine I created a new <code>filename</code> column based on the <code>thumbnail</code> column with the following GREL:</li>

<li>Because ~400 records had the same filename on Flickr (hqdefault.jpg) but different UUIDs in the URL</li>
|
|
<li>So for the <code>hqdefault.jpg</code> ones I just take the UUID (-2) and use it as the filename</li>

<li>And <code>dc.identifier.fund</code> is MOSTLY used for CPWF project identifier but has some other sponsorship things

<li>We should move PN*, SG*, CBA, IA, and PHASE* values to <code>cg.identifier.cpwfproject</code></li>
