<li>The two most often requesters are in Ethiopia and Colombia: 213.55.99.121 and 181.118.144.29</li>

<li>It looks like Sisay was doing some batch imports</li>

<li>Hmm, also disk space is full</li>
|

<li>I decided to blow away the solr indexes, since they are 50GB and we don’t really need all the Atmire stuff there right now</li>

<ul>
|

<li>Start looking at more metadata migrations</li>
|
|
<li>There are lots of fields in <code>dcterms</code> namespace that look interesting, like:
|
|
|
|
<ul>
|
|
<li>dcterms.type</li>
|
|
<li>dcterms.spatial</li>
|
|
</ul></li>
|
|
<li>Not sure what <code>dcterms</code> is…</li>
|
|
<li>Looks like these were <a href="https://wiki.duraspace.org/display/DSDOC5x/Metadata+and+Bitstream+Format+Registries#MetadataandBitstreamFormatRegistries-DublinCoreTermsRegistry(DCTERMS)">added in DSpace 4</a> to allow for future work to make DSpace more flexible</li>
|
|
<li>CGSpace’s <code>dc</code> registry has 96 items, and the default DSpace one has 73.</li>
