<li>The results look fantastic! So the <code>random_page_cost</code> tweak is massively important for informing the PostgreSQL scheduler that there is no “cost” to accessing random pages, as we’re on an SSD!</li>

<li>Reboot DSpace Test to get new Linode Linux kernel</li>
|
||
<li>Looking at CCAFS bulk import for Magdalena Haman (she originally sent them in November but some of the thumbnails were missing and dates were messed up so she resent them now)</li>
|
||
<li>A few issues with the data and thumbnails:
|
||
|
||
<ul>
|
||
<li>Her thumbnail files all use capital JPG so I had to rename them to lowercase: <code>rename -fc *.JPG</code></li>
|
||
<li>thumbnail20.jpg is 1.7MB so I have to resize it</li>
|
||
<li>I also had to add the .jpg to the thumbnail string in the CSV</li>
|
||
<li>The thumbnail11.jpg is missing</li>
|
||
<li>The dates are in super long ISO8601 format (from Excel?) like <code>2016-02-07T00:00:00Z</code> so I converted them to simpler forms in GREL: <code>value.toString("yyyy-MM-dd")</code></li>
|
||
<li>I trimmed the whitespaces in a few fields but it wasn’t many</li>
|
||
<li>Rename her thumbnail column to filename, and format it so SAFBuilder adds the files to the thumbnail bundle with this GREL in OpenRefine: <code>value + "__bundle:THUMBNAIL"</code></li>
|
||
<li>Rename dc.identifier.status and dc.identifier.url columns to cg.identifier.status and cg.identifier.url</li>
|
||
<li>Item 4 has weird characters in citation, ie: Nagoya et de Trait</li>
|
||
<li>Some author names need normalization, ie: <code>Aggarwal, Pramod</code> and <code>Aggarwal, Pramod K.</code></li>
|
||
<li>Something weird going on with duplicate authors that have the same text value, like <code>Berto, Jayson C.</code> and <code>Balmeo, Katherine P.</code></li>
|
||
<li>I will send her feedback on some author names like UNEP and ICRISAT and ask her for the missing thumbnail11.jpg</li>
|
||
</ul></li>
|
||
<li>I did a test import of the data locally after building with SAFBuilder but for some reason I had to specify the collection (even though the collections were specified in the <code>collection</code> field)</li>
