<li>Uptime Robot noticed that CGSpace went down and up a few times last night, for a few minutes each time</li>
<li>I didn&rsquo;t get any load alerts from Linode and the REST and XMLUI logs don&rsquo;t show anything out of the ordinary</li>
<li>The nginx logs show HTTP 200s until <code>02/Jan/2018:11:27:17 +0000</code> when Uptime Robot got an HTTP 500</li>
<li>In dspace.log around that time I see many errors like &ldquo;Client closed the connection before file download was complete&rdquo;</li>

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

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