I restarted it again now and told Moayad that the automatic indexing isn&rsquo;t working
Add Alliance of Bioversity International and CIAT to affiliations on CGSpace
Abenet told me that the general search text on AReS doesn&rsquo;t get reset when you use the &ldquo;Reset Filters&rdquo; button

<li>I still need to create a cron job for this&hellip;</li>
<li>Sisay and Abenet said they can&rsquo;t log in with LDAP on DSpace Test (DSpace 6)
<ul>
<li>I tried and I can&rsquo;t either&hellip; but it is working on CGSpace</li>
<li>The error on DSpace 6 is:</li>

<li>According to the <a href="https://wiki.lyrasis.org/display/DSDOC6x/Authentication+Plugins#AuthenticationPlugins-LDAPAuthentication">DSpace 6 docs</a> we need to escape commas in our LDAP parameters due to the new configuration system
<ul>
<li>I added the commas and restarted DSpace (though technically we shouldn&rsquo;t need to restart due to the new config system hot reloading configs)</li>
<li>Run all system updates on DSpace Test (linode26) and reboot it</li>

<li>Fix some erroneous &ldquo;review status&rdquo; fields that Abenet noticed on AReS

<li>Start reviewing 95 items for IITA (20201stbatch)
<ul>
<li>I used my <a href="https://github.com/ilri/csv-metadata-quality">csv-metadata-quality</a> tool to check and fix some low-hanging fruit first</li>
<li>This fixed a few unnecessary Unicode, excessive whitespace, invalid multi-value separator, and duplicate metadata values</li>
<li>Then I looked at the data in OpenRefine and noticed some things:
<ul>
<li>All issue dates use year only, but some have months in the citation so they could be more specific</li>
<li>I normalized all the DOIs to use &ldquo;<a href="https://doi.org">https://doi.org</a>&rdquo; format</li>
<li>I fixed a few AGROVOC subjects with a simple GREL: <code>value.replace(&quot;GRAINS&quot;,&quot;GRAIN&quot;).replace(&quot;SOILS&quot;,&quot;SOIL&quot;).replace(&quot;CORN&quot;,&quot;MAIZE&quot;)</code></li>
<li>But there are a few more that are invalid that she will have to look at</li>
<li>I uploaded the items to <a href="https://dspacetest.cgiar.org/handle/10568/108357">DSpace Test</a> and it was apparently successful but I get these errors to the console:</li>

<ul>
<li>I was checking the recent IITA data for duplicates when I noticed that one in CIFOR&rsquo;s Archive and saw that CIFOR has updated a bunch of their website URLs, for example:
<ul>
<li><a href="http://www.cifor.org/nc/online-library/browse/view-publication/publication/151.html">http://www.cifor.org/nc/online-library/browse/view-publication/publication/151.html</a> → <a href="https://www.cifor.org/knowledge/publication/151">https://www.cifor.org/knowledge/publication/151</a></li>
<li><a href="https://www.cifor.org/library/4033">https://www.cifor.org/library/4033</a> → <a href="https://www.cifor.org/knowledge/publication/4033">https://www.cifor.org/knowledge/publication/4033</a></li>
<li><a href="https://www.cifor.org/pid/5087">https://www.cifor.org/pid/5087</a> → <a href="https://www.cifor.org/knowledge/publication/5087">https://www.cifor.org/knowledge/publication/5087</a></li>
</ul>
</li>
<li>I will update our nearly 6,000 metadata values for CIFOR in the database accordingly:</li>
</ul>
<pre><code>dspace=# UPDATE metadatavalue SET text_value = regexp_replace(text_value, '^(http://)?www\.cifor\.org/(nc/)?online-library/browse/view-publication/publication/([[:digit:]]+)\.html$', 'https://www.cifor.org/knowledge/publication/\3') WHERE metadata_field_id=219 AND text_value ~ 'www\.cifor\.org/(nc/)?online-library/browse/view-publication/publication/[[:digit:]]+';

</code></pre><ul>
<li>I did some cleanup on the author affiliations of the IITA data our 2019-04 list using reconcile-csv and OpenRefine:
<ul>
<li><code>$ lein run ~/src/git/DSpace/2019-04-08-affiliations.csv name id</code></li>
<li>I always forget how to copy the reconciled values in OpenRefine, but you need to make a new column and populate it using this GREL: <code>if(cell.recon.matched, cell.recon.match.name, value)</code></li>
</ul>
</li>
<li>I mapped one duplicated from the CIFOR Archives and re-uploaded the 94 IITA items to a new collection on <a href="https://dspacetest.cgiar.org/handle/10568/108453">DSpace Test</a></li>
</ul>
<h2 id="2020-09-08">2020-09-08</h2>

<li>I noticed that the &ldquo;share&rdquo; link in AReS wasn&rsquo;t working properly because it excludes the &ldquo;explorer&rdquo; part of the URI</li>
</ul>
<p><img src="/cgspace-notes/2020/09/ares-share-link.png" alt="AReS share link broken"></p>
<ul>
<li>I filed an issue on GitHub: <a href="https://github.com/ilri/OpenRXV/issues/41">https://github.com/ilri/OpenRXV/issues/41</a></li>
<li>I uploaded the 94 IITA items that I had been working on last week to CGSpace</li>
<li>RTB emailed to ask why they are getting HTTP 503 errors during harvesting to the RTB WordPress website
<ul>
<li>From the screenshot I can see they are requesting URLs like this:</li>
</ul>
</li>
</ul>
<pre><code>https://cgspace.cgiar.org/bitstream/handle/10568/82745/Characteristics-Silage.JPG
</code></pre><ul>
<li>So they end up getting rate limited due to the XMLUI rate limits
<ul>
<li>I told them to use the REST API bitstream retrieve links, because we don&rsquo;t have any rate limits there</li>
</ul>
</li>
</ul>
<h2 id="2020-09-09">2020-09-09</h2>
<ul>
<li>Wire up the systemd service/timer for the CGSpace Country Code Tagger curation task in the <a href="https://github.com/ilri/rmg-ansible-public">Ansible infrastructure scripts</a>
<ul>
<li><del>For now it won&rsquo;t work on DSpace 6 because the curation task invocation needs to be slightly different (minus the <code>-l</code> parameter) and for some reason the task isn&rsquo;t working on DSpace Test (version 6) right now</del></li>
<li>I added DSpace 6 support to the playbook templates&hellip;</li>
</ul>
</li>
<li>Run system updates on DSpace Test (linode26), re-deploy the DSpace 6 test branch, and reboot the server
<ul>
<li>After rebooting I deleted old copies of the cgspace-java-helpers JAR in the DSpace lib directory and then the curation worked</li>
<li>To my great surprise the curation worked (and completed, albeit a few times slower) on my local DSpace 6 environment as well:</li>
</ul>

<li>I think we need to wait for the web team, though, as they need to update their mappings
<ul>
<li>Not to mention that we&rsquo;ll need to give WLE and CCAFS time to update their harvesters as well&hellip; hmmm</li>
</ul>
</li>
<li>Looking at the top user agents active on CGSpace in 2020-08 and I see:
<ul>
<li><code>Delphi 2009</code>: 235353 (this is GARDIAN harvester I guess, as the IP is in Greece)</li>
<li><code>Mozilla/4.5 (compatible; HTTrack 3.0x; Windows 98)</code>: 57004 (IP is 18.196.100.94, and the requests seem to be for CTA&rsquo;s content)</li>
<li><code>RTB website BOT</code>: 12282</li>
<li><code>ILRI Livestock Website Publications importer BOT</code>: 9393</li>
</ul>
</li>
<li>Shit, I meant to add Delphi to the DSpace spider agents list last month but I guess I didn&rsquo;t commit the change</li>
<li>HTTrack is in the agents list so I&rsquo;m not sure why DSpace registers a hit from that request</li>
<li>Also, I am surprised to see the RTB and ILRI bots here because they have &ldquo;BOT&rdquo; in the name and that should also be dropped</li>
<li>I also see hits from <code>curl</code> and <code>Java/1.8.0_66</code> and <code>Apache-HttpClient</code> so WTF&hellip; those are supposed to be dropped by the default agents list</li>
<li>Some IP <code>2607:f298:5:101d:f816:3eff:fed9:a484</code> made 9,000 requests with the <code>RI/1.0</code> user agent this year&hellip;
<ul>
<li>That&rsquo;s on DreamHost&hellip;?</li>
</ul>
</li>
<li>I purged 448658 hits from these agents and added <code>Delphi</code> to our local agents overload for Solr as well as Tomcat&rsquo;s Crawler Session Manager Valve so that it forces them to re-use a single session</li>
<li>I made a pull request on the COUNTER-Robots project for the Daum robot: <a href="https://github.com/atmire/COUNTER-Robots/pull/38">https://github.com/atmire/COUNTER-Robots/pull/38</a>
<ul>
<li>This bot made 8,000 requests to CGSpace this year</li>
<li>I purged about 20,000 total requests from this bot from our Solr stats for the last few years</li>
</ul>
</li>
</ul>
<h2 id="2020-09-11">2020-09-11</h2>
<ul>
<li>Peter noticed that an export from AReS shows some items with zero views and others with zero views/downloads, but on CGSpace and in the statistics API there are views/downloads
<ul>
<li>I need to ask Moayad&hellip;</li>
</ul>
</li>
</ul>
<h2 id="2020-09-12">2020-09-12</h2>
<ul>
<li>Carlos Tejo from the LandPortal emailed to ask for advice about integrating their <a href="https://landvoc.org/">LandVoc</a> vocabulary, which is a subset of AGROVOC, into DSpace
<ul>
<li>I told him that they could use the DSpace authority control framework and sent an example of the VIAFAuthority from the DSpace-CRIS project: <a href="https://github.com/4Science/DSpace/blob/dspace-6_x_x-cris/dspace-api/src/main/java/org/dspace/content/authority/VIAFAuthority.java">https://github.com/4Science/DSpace/blob/dspace-6_x_x-cris/dspace-api/src/main/java/org/dspace/content/authority/VIAFAuthority.java</a></li>
</ul>
</li>
<li>Redeploy the latest <code>5_x-prod</code> branch on CGSpace, re-run the latest Ansible DSpace playbook, run all system updates, and reboot the server (linode18)
<ul>
<li>This will bring the latest bot lists for Solr and Tomcat</li>
<li>I had to restart Tomcat 7 three times before all Solr statistics cores came up OK</li>
</ul>
</li>
<li>Leroy and Carol from CIAT/Bioversity were asking for information about posting to the CGSpace REST API from Sharepoint
<ul>
<li>I told them that we don&rsquo;t allow this yet, but that we need to check in the future whether content can be posted to a workflow</li>
</ul>
</li>
</ul>
<h2 id="2020-09-15">2020-09-15</h2>
<ul>
<li>Charlotte from Altmetric said they had issues parsing the XML file I sent them last month
<ul>
<li>I told them that it was mimicking the same format that they had sent me (fourteen pages of XML responses concatenated together)!</li>
</ul>
</li>
<li>A few days ago IWMI asked us if we can add a new field on CGSpace for their library identifier
<ul>
<li>The IDs look like this: H049940</li>
<li>I suggested that we use <code>cg.identifier.iwmilibrary</code></li>
<li>I added it to the input forms and push it to the <code>5_x-prod</code> and 6.x branches and will re-deploy it in the next few days</li>
</ul>
</li>
<li>Abenet asked me to import sixty-nine (69) CIP Annual Reports to CGSpace
<ul>
<li>I looked at the data in OpenRefine and it is very good quality</li>
<li>I only added descriptions to the filename field so that SAFBuilder will add them to the bitstreams on import:</li>
</ul>
</li>
</ul>
<pre><code>value + &quot;__description:&quot; + cells[&quot;dc.type&quot;].value
</code></pre><ul>
<li>Then I created a SAF bundle with SAFBuilder:</li>
</ul>
<pre><code>$ ./safbuilder.sh -c ~/Downloads/cip-annual-reports/cip-reports.csv
</code></pre><ul>
<li>And imported them into my local test instance of CGSpace:</li>
</ul>
<pre><code>$ ~/dspace/bin/dspace import -a -e y.arrr@cgiar.org -m /tmp/2020-09-15-cip-annual-reports.map -s ~/Downloads/cip-annual-reports/SimpleArchiveFormat
</code></pre><ul>
<li>Then I uploaded them to CGSpace</li>

<ul>
<li>Looking further into Carlos Tejos&rsquo;s question about integrating LandVoc (the AGROVOC subset) into DSpace
<ul>
<li>I see that you can actually get LandVoc concepts directly from AGROVOC&rsquo;s SPARQL, for example with <a href="http://agrovoc.uniroma2.it/sparql#query=PREFIX+rdfs%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2000%2F01%2Frdf-schema%23%3E%0APREFIX+skos%3A+%3Chttp%3A%2F%2Fwww.w3.org%2F2004%2F02%2Fskos%2Fcore%23%3E%0A%0ASELECT+%3Fconcept%0AWHERE+%7B%0A++%3Fconcept+a+skos%3AConcept+%3B%0A+++++++++++skos%3AinScheme+%3Chttp%3A%2F%2Flandvoc.org%2Flandvoc%3E+.%0A%0A%7D+ORDER+BY+%3Fconcept&amp;contentTypeConstruct=text%2Fturtle&amp;contentTypeSelect=application%2Fsparql-results%2Bjson&amp;endpoint=http%3A%2F%2Fagrovoc.uniroma2.it%2Fsparql&amp;requestMethod=POST&amp;tabTitle=Query&amp;headers=%7B%7D&amp;outputFormat=table">this query</a></li>
</ul>
</li>
</ul>
<p><img src="/cgspace-notes/2020/09/agrovoc-landvoc-sparql.png" alt="AGROVOC LandVoc SPARQL"></p>
<ul>
<li>So maybe we can query AGROVOC directly using a similar method to <a href="https://github.com/4Science/DSpace/blob/dspace-5_x_x-cris/dspace-api/src/main/java/org/dspace/content/authority/TGNAuthority.java">DSpace-CRIS&rsquo;s GettyAuthority</a></li>
<li>I wired up DSpace-CRIS&rsquo;s VIAFAuthority to see how authorities for auto suggested names get stored
<ul>
<li>After submission you can see the item&rsquo;s VIAF identifier:</li>
</ul>
</li>
</ul>
<p><img src="/cgspace-notes/2020/09/viaf-authority.png" alt="VIAF authority"></p>
<ul>
<li>And this identifier is the ID on VIAF, pretty cool!</li>
</ul>
<p><img src="/cgspace-notes/2020/09/viaf-darwin.png" alt="VIAF entry for Charles Darwin"></p>
<ul>
<li>I did a similar test with the Getty Thesaurus of Geographic Names (TGN) and it stores the concept URI in the authority:</li>
</ul>
<p><img src="/cgspace-notes/2020/09/tgn-concept-uri.png" alt="TGNAuthority"></p>
<ul>
<li>But the authority values are not exposed anywhere as metadata&hellip;
<ul>
<li>I need to play with it a bit more I guess&hellip;</li>
</ul>
</li>
<li>The nice thing is that the Getty example from DSpace-CRIS uses SPARQL as well, and the TGN authority extends it
<ul>
<li>We could use a similar model for AGROVOC/LandVoc very easily</li>
</ul>
</li>
