A few users noticed that CGSpace wasn&rsquo;t loading items today, item pages seem blank
I looked at the PostgreSQL locks but they don&rsquo;t seem unusual
I guess this is the same &ldquo;blank item page&rdquo; issue that we had a few times in 2019 that we never solved
I restarted Tomcat and PostgreSQL and the issue was gone
Since I was restarting Tomcat anyways I decided to redeploy the latest changes from the 5_x-prod branch and I added a note about COVID-19 items to the CGSpace frontpage at Peter&rsquo;s request

<li>Also, Linode is alerting that we had high outbound traffic rate early this morning around midnight AND high CPU load later in the morning</li>
<li>First looking at the traffic in the morning:</li>
</ul>
<pre><code># cat /var/log/nginx/*.log.1 /var/log/nginx/*.log | grep -E &quot;01/Jul/2020:(00|01|02|03|04)&quot; | goaccess --log-format=COMBINED -

<li>64.39.99.13 belongs to Qualys, but I see they are using a normal desktop user agent:</li>
</ul>
<pre><code>Mozilla/5.0 (Macintosh; Intel Mac OS X 10_14_5) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/12.1.1 Safari/605.1.15
</code></pre><ul>
<li>I will purge hits from that IP from Solr</li>
<li>The 199.47.87.x IPs belong to Turnitin, and apparently they are NOT marked as bots and we have 40,000 hits from them in 2020 statistics alone:</li>
</ul>
<pre><code>$ curl -s &quot;http://localhost:8081/solr/statistics/select&quot; -d &quot;q=userAgent:/Turnitin.*/&amp;rows=0&quot; | grep -oE 'numFound=&quot;[0-9]+&quot;'

<li>They used to be &ldquo;TurnitinBot&rdquo;&hellip; hhmmmm, seems they use both: <a href="https://turnitin.com/robot/crawlerinfo.html">https://turnitin.com/robot/crawlerinfo.html</a></li>
<li>I will add Turnitin to the DSpace bot user agent list, but I see they are reqesting <code>robots.txt</code> and only requesting item pages, so that&rsquo;s impressive! I don&rsquo;t need to add them to the &ldquo;bad bot&rdquo; rate limit list in nginx</li>
<li>While looking at the logs I noticed eighty-one IPs in the range 185.152.250.x making little requests this user agent:</li>

<li>It&rsquo;s only a few hundred requests each, but I am very suspicious so I will record it here and purge their IPs from Solr</li>
<li>Then I see 185.187.30.14 and 185.187.30.13 making requests also, with several different &ldquo;normal&rdquo; user agents
<ul>
<li>They are both apparently in France, belonging to Scalair FR hosting</li>
<li>I will purge their requests from Solr too</li>
</ul>
</li>
<li>Now I see some other new bots I hadn&rsquo;t noticed before:
<ul>
<li><code>Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0) LinkCheck by Siteimprove.com</code></li>
<li><code>Consilio (WebHare Platform 4.28.2-dev); LinkChecker)</code>, which appears to be a <a href="https://www.utwente.nl/en/websites/webhare/">university CMS</a></li>
<li>I will add <code>LinkCheck</code>, <code>Consilio</code>, and <code>WebHare</code> to the list of DSpace bot agents and purge them from Solr stats</li>
<li>COUNTER-Robots list already has <code>link.?check</code> but for some reason DSpace didn&rsquo;t match that and I see hits for some of these&hellip;</li>
<li>Maybe I should add <code>[Ll]ink.?[Cc]heck.?</code> to a custom list for now?</li>
<li>For now I added <code>Turnitin</code> to the <a href="https://github.com/atmire/COUNTER-Robots/pull/34">new bots pull request on COUNTER-Robots</a></li>
</ul>
</li>
<li>I purged 20,000 hits from IPs and 45,000 hits from user agents</li>
<li>I will revert the default &ldquo;example&rdquo; agents file back to the upstream master branch of COUNTER-Robots, and then add all my custom ones that are pending in pull requests they haven&rsquo;t merged yet:</li>

<li>I had told Atmire about this several weeks ago&hellip; but I reminded them again in the ticket
<ul>
<li>Atmire says they are able to build fine, so I tried again and noticed that I had been building with <code>-Denv=dspacetest.cgiar.org</code>, which is not necessary for DSpace 6 of course</li>
<li>Once I removed that it builds fine</li>
</ul>
</li>
<li>I quickly re-applied the Font Awesome 5 changes to use SVG+JS instead of web fonts (from 2020-04) and things are looking good!</li>
<li>Run all system updates on DSpace Test (linode26), deploy latest <code>6_x-dev-atmire-modules</code> branch, and reboot it</li>

<li>I need to export some Solr statistics data from CGSpace to test Salem&rsquo;s modifications to the dspace-statistics-api
<ul>
<li>He modified it to query Solr on the fly instead of indexing it, which will be heavier and slower, but allows us to get more granular stats and countries/cities</li>
<li>Because have so many records I want to use solr-import-export-json to get several months at a time with a date range, but it seems there are first issues with curl (need to disable globbing with <code>-g</code> and URL encode the range)</li>
<li>For reference, the <a href="https://lucene.apache.org/solr/4_10_2/solr-core/org/apache/solr/schema/DateField.html">Solr 4.10.x DateField docs</a></li>
<li>This range works in Solr UI: <code>[2019-01-01T00:00:00Z TO 2019-06-30T23:59:59Z]</code></li>
<li>As well in curl:</li>

<li>Import twelve items into the <a href="https://hdl.handle.net/10568/97076">CRP Livestock multimedia</a> collection for Peter Ballantyne
<ul>
<li>I ran the data through csv-metadata-quality first to validate and fix some common mistakes</li>
<li>Interesting to check the data with <code>csvstat</code> to see if there are any duplicates</li>
</ul>
</li>
<li>Peter recently asked me to add Target audience (<code>cg.targetaudience</code>) to the CGSpace sidebar facets and AReS filters
<ul>
<li>I added it on my local DSpace test instance, but I&rsquo;m waiting for him to tell me what he wants the header to be &ldquo;Audiences&rdquo; or &ldquo;Target audience&rdquo; etc&hellip;</li>
</ul>
</li>
<li>Peter also asked me to increase the size of links in the CGSpace &ldquo;Welcome&rdquo; text
<ul>
<li>I suggested using the CSS <code>font-size: larger</code> property to just bump it up one relative to what it already is</li>
<li>He said it looks good, but that actually now the links seem OK (I told him to refresh, as I had made them bold a few days ago) so we don&rsquo;t need to adjust it actually</li>
</ul>
</li>
<li>Mohammed Salem modified my <a href="https://github.com/ilri/dspace-statistics-api">dspace-statistics-api</a> to query Solr directly so I started writing a script to benchmark it today
<ul>
<li>I will monitor the JVM memory and CPU usage in visualvm, just like I did in 2019-04</li>
<li>I noticed an issue with his limit parameter so I sent him some feedback on that in the meantime</li>
</ul>
</li>
<li>I noticed that we have 20,000 distinct values for <code>dc.subject</code>, but there are at least 500 that are lower or mixed case that we should simply uppercase without further thought:</li>
</ul>
<pre><code>dspace=# UPDATE metadatavalue SET text_value=UPPER(text_value) WHERE resource_type_id=2 AND metadata_field_id=57 AND text_value ~ '[[:lower:]]';
</code></pre><ul>
<li>DSpace Test needs a different query because it is running DSpace 6 with UUIDs for everything:</li>
</ul>
<pre><code>dspace63=# UPDATE metadatavalue SET text_value=UPPER(text_value) WHERE dspace_object_id IN (SELECT uuid FROM item) AND metadata_field_id=57 AND text_value ~ '[[:lower:]]';
</code></pre><ul>
<li>Note the use of the POSIX character class :)</li>
<li>I suggest that we generate a list of the top 5,000 values that don&rsquo;t match AGROVOC so that Sisay can correct them
<ul>
<li>Start by getting the top 6,500 subjects (assuming that the top ~1,500 are valid from our previous work):</li>
</ul>
</li>
</ul>
<pre><code>dspace=# \COPY (SELECT DISTINCT text_value, count(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=57 GROUP BY text_value ORDER BY count DESC) TO /tmp/2020-07-05-subjects.csv WITH CSV;

<li>I made some optimizations to the suite of Python utility scripts in our DSpace directory as well as the <a href="https://github.com/ilri/csv-metadata-quality">csv-metadata-quality</a> script
<ul>
<li>Mostly to make more efficient usage of the requests cache and to use parameterized requests instead of building the request URL by concatenating the URL with query parameters</li>
</ul>
</li>
<li>I modified the <code>agrovoc-lookup.py</code> script to save its results as a CSV, with the subject, language, type of match (preferred, alternate, and total number of matches) rather than save two separate files
<ul>
<li>Note that I see <code>prefLabel</code>, <code>matchedPrefLabel</code>, and <code>altLabel</code> in the REST API responses and I&rsquo;m not sure what the second one means</li>
<li>I emailed FAO&rsquo;s AGROVOC contact to ask them</li>
<li>They responded to say that <code>matchedPrefLabel</code> is not a property in SKOS/SKOSXL vocabulary, but their SKOSMOS system seems to use it to hint that the search terms matched a <code>prefLabel</code> in another language</li>
<li>I will treat the <code>matchedPrefLabel</code> values as if they were <code>prefLabel</code> values for the indicated language then</li>

<pre><code>dspace=# \COPY (SELECT DISTINCT text_value as &quot;dc.description.sponsorship&quot;, count(text_value) FROM metadatavalue WHERE resource_type_id=2 AND metadata_field_id=29 GROUP BY &quot;dc.description.sponsorship&quot; ORDER BY count DESC) TO /tmp/2020-07-07-sponsors.csv WITH CSV HEADER;
COPY 707
</code></pre><ul>
<li>I ran it quickly through my <code>csv-metadata-quality</code> tool and found two issues that I will correct with <code>fix-metadata-values.py</code> on CGSpace immediately:</li>
</ul>
<pre><code>$ cat 2020-07-07-fix-sponsors.csv
dc.description.sponsorship,correct
&quot;Ministe`re des Affaires Etrange`res et Européennes, France&quot;,&quot;Ministère des Affaires Étrangères et Européennes, France&quot;
&quot;Global Food Security Programme, United Kingdom&quot;,&quot;Global Food Security Programme, United Kingdom&quot;
$ ./fix-metadata-values.py -i 2020-07-07-fix-sponsors.csv -db dspace -u dspace -p 'fuuu' -f dc.description.sponsorship -t correct -m 29

<li>Upload the Capacity Development July newsletter to CGSpace for Ben Hack because Abenet and Bizu usually do it, but they are currently offline due to the Internet being turned off in Ethiopia

<li>I implemented the Dimensions.ai badge on DSpace Test for Peter to see, as he&rsquo;s been asking me for awhile:</li>
</ul>
<p><img src="/cgspace-notes/2020/07/dimensions-badge.png" alt="Dimensions.ai badge"></p>
<ul>
<li>It was easy once I figured out how to do the XSLT in the DSpace theme (need to get the DOI link and remove the &ldquo;<a href="https://doi.org/%22">https://doi.org/&quot;</a> from the string)
<ul>
<li>Actually this raised an issue that the Altmetric badges weren&rsquo;t enabled in our DSpace 6 branch yet because I had forgotten to copy the config</li>
<li>Also, I noticed a big issue in both our DSpace 5 and DSpace 6 branches related to the <code>$identifier_doi</code> variable being defined incorrectly and thus never getting set (has to do with DRI)</li>
<li>I fixed both and now the Altmetric badge and the Dimensions badge both appear&hellip; nice</li>
</ul>
</li>
