Experimenting with IFPRI OAI (we want to harvest their publications)
After reading the ContentDM documentation I found IFPRI&rsquo;s OAI endpoint: http://ebrary.ifpri.org/oai/oai.php
After reading the OAI documentation and testing with an OAI validator I found out how to get their publications
This is their publications set: http://ebrary.ifpri.org/oai/oai.php?verb=ListRecords&amp;from=2016-01-01&amp;set=p15738coll2&amp;metadataPrefix=oai_dc
You can see the others by using the OAI ListSets verb: http://ebrary.ifpri.org/oai/oai.php?verb=ListSets
Working on second phase of metadata migration, looks like this will work for moving CPWF-specific data in dc.identifier.fund to cg.identifier.cpwfproject and then the rest to dc.description.sponsorship

UPDATE 497
dspacetest=# update metadatavalue set metadata_field_id=29 where metadata_field_id=75;
UPDATE 14
</code></pre>
<ul>
<li>Fix a few minor miscellaneous issues in <code>dspace.cfg</code> (<a href="https://github.com/ilri/DSpace/pull/227">#227</a>)</li>
</ul>
<h2 id="2016-06-02">2016-06-02</h2>
<ul>
<li>Testing the configuration and theme changes for the upcoming metadata migration and I found some issues with <code>cg.coverage.admin-unit</code></li>
<li>Seems that the Browse configuration in <code>dspace.cfg</code> can&rsquo;t handle the &lsquo;-&rsquo; in the field name:</li>
</ul>
<pre><code>webui.browse.index.12 = subregion:metadata:cg.coverage.admin-unit:text
</code></pre>
<ul>
<li>But actually, I think since DSpace 4 or 5 (we are 5.1) the Browse indexes come from Discovery (defined in discovery.xml) so this is really just a parsing error</li>
<li>I&rsquo;ve sent a message to the DSpace mailing list to ask about the Browse index definition</li>
<li>A user was having problems with submission and from the stacktrace it looks like a Sherpa/Romeo issue</li>
<li>I found a thread on the mailing list talking about it and there is bug report and a patch: <a href="https://jira.duraspace.org/browse/DS-2740">https://jira.duraspace.org/browse/DS-2740</a></li>
<li>The patch applies successfully on DSpace 5.1 so I will try it later</li>
</ul>
<h2 id="2016-06-03">2016-06-03</h2>
<ul>
<li>Investigating the CCAFS authority issue, I exported the metadata for the Videos collection</li>
<li>The top two authors are:</li>
</ul>
<pre><code>CGIAR Research Program on Climate Change, Agriculture and Food Security::acd00765-02f1-4b5b-92fa-bfa3877229ce::500
CGIAR Research Program on Climate Change, Agriculture and Food Security::acd00765-02f1-4b5b-92fa-bfa3877229ce::600
</code></pre>
<ul>
<li>So the only difference is the &ldquo;confidence&rdquo;</li>
<li>Ok, well THAT is interesting:</li>
</ul>
<pre><code>dspacetest=# select text_value, authority, confidence from metadatavalue where metadata_field_id=3 and text_value like '%Orth, %';

<li>And now an actually relevent example:</li>
</ul>
<pre><code>dspacetest=# select count(*) from metadatavalue where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security' and confidence = 500;
count
-------

dspacetest=# select count(*) from metadatavalue where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security' and confidence != 500;
count
-------

(1 row)
</code></pre>
<ul>
<li>Trying something experimental:</li>
</ul>
<pre><code>dspacetest=# update metadatavalue set confidence=500 where metadata_field_id=3 and text_value like 'CGIAR Research Program on Climate Change, Agriculture and Food Security';
UPDATE 960
</code></pre>
<ul>
<li>And then re-indexing authority and Discovery&hellip;?</li>
<li>After Discovery reindex the CCAFS authors are all together in the Authors sidebar facet</li>
<li>The docs for the ORCiD and Authority stuff for DSpace 5 mention changing the browse indexes to use the Authority as well:</li>
</ul>
<pre><code>webui.browse.index.2 = author:metadataAuthority:dc.contributor.author:authority
</code></pre>
<ul>
<li>That would only be for the &ldquo;Browse by&rdquo; function&hellip; so we&rsquo;ll have to see what effect that has later</li>
</ul>
<h2 id="2016-06-04">2016-06-04</h2>
<ul>
<li>Re-sync DSpace Test with CGSpace and perform test of metadata migration again</li>
<li>Run phase two of metadata migrations on CGSpace (see the <a href="https://gist.github.com/alanorth/1a730bec5ac9457a8fb0e3e72c98d09c">migration notes</a>)</li>
<li>Run all system updates and reboot CGSpace server</li>
</ul>
<h2 id="2016-06-07">2016-06-07</h2>
<ul>
<li>Figured out how to export a list of the unique values from a metadata field ordered by count:</li>
</ul>
<pre><code>dspacetest=# \copy (select text_value, count(*) from metadatavalue where resource_type_id=2 and metadata_field_id=29 group by text_value order by count desc) to /tmp/sponsorship.csv with csv;
</code></pre>
<ul>
<li><p>Identified the next round of fields to migrate:</p>
<ul>
<li>dc.title.jtitle → dc.source</li>
<li>dc.crsubject.crpsubject → cg.contributor.crp</li>
<li>dc.contributor.affiliation → cg.contributor.affiliation</li>
<li>dc.Species → cg.species</li>
<li>dc.contributor.corporate → dc.contributor</li>
<li>dc.identifier.url → cg.identifier.url</li>
<li>dc.identifier.doi → cg.identifier.doi</li>
<li>dc.identifier.googleurl → cg.identifier.googleurl</li>
<li>dc.identifier.dataurl → cg.identifier.dataurl</li>
</ul></li>
<li><p>Discuss pulling data from IFPRI&rsquo;s ContentDM with Ryan Miller</p></li>
<li><p>Looks like OAI is kinda obtuse for this, and if we use ContentDM&rsquo;s API we&rsquo;ll be able to access their internal field names (rather than trying to figure out how they stuffed them into various, repeated Dublin Core fields)</p></li>
</ul>
<h2 id="2016-06-08">2016-06-08</h2>
<ul>
<li>Discuss controlled vocabularies for ~28 fields</li>
<li>Looks like this is all we need: <a href="https://wiki.duraspace.org/display/DSDOC5x/Submission+User+Interface#SubmissionUserInterface-ConfiguringControlledVocabularies">https://wiki.duraspace.org/display/DSDOC5x/Submission+User+Interface#SubmissionUserInterface-ConfiguringControlledVocabularies</a></li>
<li>I wrote an XPath expression to extract the ILRI subjects from <code>input-forms.xml</code> (uses xmlstartlet):</li>
</ul>
<pre><code>$ xml sel -t -m '//value-pairs[@value-pairs-name=&quot;ilrisubject&quot;]/pair/displayed-value/text()' -c '.' -n dspace/config/input-forms.xml
</code></pre>
<ul>
<li>Write to Atmire about the use of <code>atmire.orcid.id</code> to see if we can change it</li>
<li>Seems to be a virtual field that is queried from the authority cache&hellip; hmm</li>
<li>In other news, I found out that the About page that we haven&rsquo;t been using lives in <code>dspace/config/about.xml</code>, so now we can update the text</li>
<li>File bug about <code>closed=&quot;true&quot;</code> attribute of controlled vocabularies not working: <a href="https://jira.duraspace.org/browse/DS-3238">https://jira.duraspace.org/browse/DS-3238</a></li>
</ul>
<h2 id="2016-06-09">2016-06-09</h2>
<ul>
<li>Atmire explained that the <code>atmire.orcid.id</code> field doesn&rsquo;t exist in the schema, as it actually comes from the authority cache during XMLUI run time</li>
<li>This means we don&rsquo;t see it when harvesting via OAI or REST, for example</li>
<li>They opened a feature ticket on the DSpace tracker to ask for support of this: <a href="https://jira.duraspace.org/browse/DS-3239">https://jira.duraspace.org/browse/DS-3239</a></li>
</ul>

<ul>
<li>Investigating authority confidences</li>
<li>It looks like the values are documented in <code>Choices.java</code></li>
<li>Experiment with setting all 960 CCAFS author values to be 500:</li>
</ul>
<pre><code>dspacetest=# SELECT authority, confidence FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=3 AND text_value = 'CGIAR Research Program on Climate Change, Agriculture and Food Security';
dspacetest=# UPDATE metadatavalue set confidence = 500 where resource_type_id=2 AND metadata_field_id=3 AND text_value = 'CGIAR Research Program on Climate Change, Agriculture and Food Security';
UPDATE 960
</code></pre>
<ul>
<li>After the database edit, I did a full Discovery re-index</li>
<li>And now there are exactly 960 items in the authors facet for &lsquo;CGIAR Research Program on Climate Change, Agriculture and Food Security&rsquo;</li>
<li>Now I ran the same on CGSpace</li>
<li>Merge controlled vocabulary functionality for animal breeds to <code>5_x-prod</code> (<a href="https://github.com/ilri/DSpace/pull/236">#236</a>)</li>
<li>Write python script to update metadata values in batch via PostgreSQL: <a href="https://gist.github.com/alanorth/df92cbfb54d762ba21b28f7cd83b6897">fix-metadata-values.py</a></li>
<li>We need to use this to correct some pretty ugly values in fields like <code>dc.description.sponsorship</code></li>
<li>Merge item display tweaks from earlier this week (<a href="https://github.com/ilri/DSpace/pull/231">#231</a>)</li>
<li>Merge controlled vocabulary functionality for subregions (<a href="https://github.com/ilri/DSpace/pull/238">#238</a>)</li>
