|
||
|
||
<ul>
|
||
<li>After discussion with WLE and CGSpace content people, we decided to just add one metadata field for the WLE Research Themes</li>
|
||
<li>The <code>cg.identifier.wletheme</code> field will be used for both Phase I and Phase II Research Themes</li>
|
||
<li>Then we’ll create a new sub-community for Phase II and create collections for the research themes there</li>
|
||
<li>The current “Research Themes” community will be renamed to “WLE Phase I Research Themes”</li>
|
||
<li>Tagged all items in the current Phase I collections with their appropriate themes</li>
|
||
<li>Create pull request to add Phase II research themes to the submission form: <a href="https://github.com/ilri/DSpace/pull/328">#328</a></li>
|
||
<li>Add <code>cg.subject.system</code> to CGSpace metadata registry, for subject from the upcoming CGIAR Library migration</li>
|
||
</ul>
|
||
|
||
<h2 id="2017-06-04">2017-06-04</h2>
|
||
|
||
<ul>
|
||
<li>After adding <code>cg.identifier.wletheme</code> to 1106 WLE items I can see the field on XMLUI but not in REST!</li>
|
||
<li>Strangely it happens on DSpace Test AND on CGSpace!</li>
|
||
<li>I tried to re-index Discovery but it didn’t fix it</li>
|
||
<li>Run all system updates on DSpace Test and reboot the server</li>
|
||
<li>After rebooting the server (and therefore restarting Tomcat) the new metadata field is available</li>
|
||
<li>I’ve sent a message to the dspace-tech mailing list to ask if this is a bug and whether I should file a Jira ticket</li>
|
||
</ul>
|
||
|
||
<h2 id="2016-06-05">2016-06-05</h2>
|
||
|
||
<ul>
|
||
<li>Rename WLE’s “Research Themes” sub-community to “WLE Phase I Research Themes” on DSpace Test so Macaroni Bros can continue their testing</li>
|
||
<li>Macaroni Bros tested it and said it’s fine, so I renamed it on CGSpace as well</li>
|
||
<li>Working on how to automate the extraction of the CIAT Book chapters, doing some magic in OpenRefine to extract page from–to from cg.identifier.url and dc.format.extent, respectively:
|
||
|
||
<ul>
|
||
<li>cg.identifier.url: <code>value.split("page=", "")[1]</code></li>
|
||
<li>dc.format.extent: <code>value.replace("p. ", "").split("-")[1].toNumber() - value.replace("p. ", "").split("-")[0].toNumber()</code></li>
|
||
</ul></li>
|
||
<li>Finally, after some filtering to see which small outliers there were (based on dc.format.extent using “p. 1-14” vs “29 p.”), create a new column with last page number:
|
||
|
||
<ul>
|
||
<li><code>cells["dc.page.from"].value.toNumber() + cells["dc.format.pages"].value.toNumber()</code></li>
|
||
</ul></li>
|
||
<li>Then create a new, unique file name to be used in the output, based on a SHA1 of the dc.title and with a description:
|
||
|
||
<ul>
|
||
<li>dc.page.to: <code>value.split(" ")[0].replace(",","").toLowercase() + "-" + sha1(value).get(1,9) + ".pdf__description:" + cells["dc.type"].value</code></li>
|
||
</ul></li>
|
||
<li>Start processing 769 records after filtering the following (there are another 159 records that have some other format, or for example they have their own PDF which I will process later), using a modified <code>generate-thumbnails.py</code> script to read certain fields and then pass to GhostScript:
|
||
|
||
<ul>
|
||
<li>cg.identifier.url: <code>value.contains("page=")</code></li>
|
||
<li>dc.format.extent: <code>or(value.contains("p. "),value.contains(" p."))</code></li>
|
||
<li>Command like: <code>$ gs -dNOPAUSE -dBATCH -dFirstPage=14 -dLastPage=27 -sDEVICE=pdfwrite -sOutputFile=beans.pdf -f 12605-1.pdf</code></li>
|
||
</ul></li>
|
||
<li>17 of the items have issues with incorrect page number ranges, and upon closer inspection they do not appear in the referenced PDF</li>
|
||
|
||
<li><p>I’ve flagged them and proceeded without them (752 total) on DSpace Test:</p>
|
||
|
||
<pre><code>$ JAVA_OPTS="-Xmx1024m -Dfile.encoding=UTF-8" [dspace]/bin/dspace import --add --eperson=aorth@mjanja.ch --collection=10568/93843 --source /home/aorth/src/CIAT-Books/SimpleArchiveFormat/ --mapfile=/tmp/ciat-books.map &> /tmp/ciat-books.log
|
||
</code></pre></li>
|
||
|
||
<li><p>I went and did some basic sanity checks on the remaining items in the CIAT Book Chapters and decided they are mostly fine (except one duplicate and the flagged ones), so I imported them to DSpace Test too (162 items)</p></li>
|
||
|
||
<li><p>Total items in CIAT Book Chapters is 914, with the others being flagged for some reason, and we should send that back to CIAT</p></li>
|
||
|
||
<li><p>Restart Tomcat on CGSpace so that the <code>cg.identifier.wletheme</code> field is available on REST API for Macaroni Bros</p></li>
|
||

<ul>
|
||
<li>Testing <a href="https://github.com/ilri/DSpace/pull/319">Atmire’s patch for the CUA Workflow Statistics again</a></li>
|
||
<li>Still doesn’t seem to give results I’d expect, like there are no results for Maria Garruccio, or for the ILRI community!</li>
|
||
<li>Then I’ll file an update to the issue on Atmire’s tracker</li>
|
||
<li>Created a new branch with just the relevant changes, so I can send it to them</li>
|
||
|
||
<li><p>One thing I noticed is that there is a failed database migration related to CUA:</p>

<pre><code>Java stacktrace: java.util.NoSuchElementException: Timeout waiting for idle object

|
||
<li><p>After looking at the Tomcat logs, Munin graphs, and PostgreSQL connection stats, it seems there is just a high load</p></li>
|
||
|
||
<li><p>Might be a good time to adjust DSpace’s database connection settings, like I first mentioned in April, 2017 after reading the <a href="https://wiki.duraspace.org/display/cmtygp/DCAT+Meeting+April+2017">2017-04 DCAT comments</a></p></li>
|
||
|

<li><p>I’ve adjusted the following in CGSpace’s config:</p>
|
||
|
||
<ul>
|
||
<li><code>db.maxconnections</code> 30→70 (the default PostgreSQL config allows 100 connections, so DSpace’s default of 30 is quite low)</li>
|
||
<li><code>db.maxwait</code> 5000→10000</li>
|
||
<li><code>db.maxidle</code> 8→20 (DSpace default is -1, unlimited, but we had set it to 8 earlier)</li>
|
||
</ul></li>
|
||
|
||
<li><p>We will need to adjust this again (as well as the <code>pg_hba.conf</code> settings) when we deploy tsega’s REST API</p></li>
