Spend some time testing my post_bitstreams.py script to update thumbnails for items on CGSpace
Interestingly I found an item with a JFIF thumbnail and another with a WebP thumbnail…
Meeting with Valentina, Stefano, and Sara about MODS metadata in CGSpace
They have experience with improving the MODS interface in MELSpace’s OAI-PMH for use with AGRIS and were curious if we could do the same in CGSpace
From what I can see we need to upgrade the MODS schema from 3.1 to 3.7 and then just add a bunch of our fields to the crosswalk

<li>The upgrade was mostly normal, but I had to unhold the openjdk package in order for <code>do-release-upgrade</code> to run:</li>

<li>In <ahref="/cgspace-notes/2022-11/">2022-11</a> an upstream Java update broke the DSpace 6 Handle server so we will have to pin this again after the upgrade to Ubuntu 22.04</li>
<li>After the upgrade I made sure CGSpace was working, then proceeded to upgrade PostgreSQL from 12 to 14, like I did on <ahref="/cgspace-notes/2023-03/">DSpace Test in 2023-03</a></li>
<li>Then I had to downgrade OpenJDK to fix the Handle server using the ones I had previously downloaded for Ubuntu 20.04 because they no longer exist on Launchpad:</li>
<li>Continue working on the MODS schema mapping</li>
<li>Export CGSpace to check and update <code>dcterms.extent</code> fields
<ul>
<li>I normalized about 1,500 to use either “p. 1-6” or “5 p.” format</li>
<li>Also, I used this GREL expression to extract missing pages from the citation field: <code>cells['dcterms.bibliographicCitation[en_US]'].value.match(/.*(pp?\.\s?\d+[-–]\d+).*/)[0]</code></li>
<li>This was over 4,000 items with a format like “p. 1-6” and “pp. 1-6” in the citation</li>
<li>I used another GREL expression to extract another 5,000: <code>cells['dcterms.bibliographicCitation[en_US]'].value.match(/.*?(\d+\s+?[Pp]+\.).*/)[0]</code></li>
<li>This was for the format like “1 p.” (note we had to protect against the greedy <code>.*</code> in the beginning)</li>
</ul>
</li>
<li>I also did some work to capture a handful of missing DOIs and ISSNs, but it was only about 100 items and I will have to wait until the 10,000+ above finish importing</li>
