I wrote a script to query Sherpa&rsquo;s API for our ISSNs: sherpa-issn-lookup.py
I&rsquo;m curious to see how the results compare with the results from Crossref yesterday
AReS Explorer was down since this morning, I didn&rsquo;t see anything in the systemd journal
I simply took everything down with docker-compose and then back up, and then it was OK
Perhaps one of the containers crashed, I should have looked closer but I was in a hurry

<ul>
<li>I wrote a script to query Sherpa&rsquo;s API for our ISSNs: <code>sherpa-issn-lookup.py</code>
<ul>
<li>I&rsquo;m curious to see how the results compare with the results from Crossref yesterday</li>
</ul>
</li>
<li>AReS Explorer was down since this morning, I didn&rsquo;t see anything in the systemd journal

<ul>
<li>Biruk from ICT contacted me to say that some CGSpace users still can&rsquo;t log in
<ul>
<li>I guess the CGSpace LDAP bind account is really still locked after last week&rsquo;s reset</li>
<li>He fixed the account and then I was finally able to bind and query:</li>
</ul>
</li>
</ul>
<pre><code class="language-console" data-lang="console">$ ldapsearch -x -H ldaps://AZCGNEROOT2.CGIARAD.ORG:636/ -b &quot;dc=cgiarad,dc=org&quot; -D &quot;cgspace-account&quot; -W &quot;(sAMAccountName=otheraccounttoquery)&quot;
</code></pre><h2 id="2021-04-04">2021-04-04</h2>
<ul>
<li>Check the index aliases on AReS Explorer to make sure they are sane before starting a new harvest:</li>
</ul>
<pre><code class="language-console" data-lang="console">$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool | less
</code></pre><ul>
<li>Then set the <code>openrxv-items-final</code> index to read-only so we can make a backup:</li>
</ul>
<pre><code class="language-console" data-lang="console">$ curl -X PUT &quot;localhost:9200/openrxv-items-final/_settings&quot; -H 'Content-Type: application/json' -d'{&quot;settings&quot;: {&quot;index.blocks.write&quot;: true}}'
{&quot;acknowledged&quot;:true}%
$ curl -s -X POST http://localhost:9200/openrxv-items-final/_clone/openrxv-items-final-backup
{&quot;acknowledged&quot;:true,&quot;shards_acknowledged&quot;:true,&quot;index&quot;:&quot;openrxv-items-final-backup&quot;}%
$ curl -X PUT &quot;localhost:9200/openrxv-items-final/_settings&quot; -H 'Content-Type: application/json' -d'{&quot;settings&quot;: {&quot;index.blocks.write&quot;: false}}'
</code></pre><ul>
<li>Then start a harvesting on AReS Explorer</li>
<li>Help Enrico get some 2020 statistics for the Roots, Tubers and Bananas (RTB) community on CGSpace
<ul>
<li>He was hitting <a href="https://github.com/ilri/OpenRXV/issues/66">a bug on AReS</a> and also he only needed stats for 2020, and AReS currently only gives all-time stats</li>
</ul>
</li>
<li>I cleaned up about 230 ISSNs on CGSpace in OpenRefine
<ul>
<li>I had exported them last week, then filtered for anything not looking like an ISSN with this GREL: <code>isNotNull(value.match(/^\p{Alnum}{4}-\p{Alnum}{4}$/))</code></li>
<li>Then I applied them on CGSpace with the <code>fix-metadata-values.py</code> script:</li>
</ul>
</li>
</ul>
<pre><code class="language-console" data-lang="console">$ ./ilri/fix-metadata-values.py -i /tmp/2021-04-01-ISSNs.csv -db dspace -u dspace -p 'fuuu' -f cg.issn -t 'correct' -m 253
</code></pre><ul>
<li>For now I only fixed obvious errors like &ldquo;1234-5678.&rdquo; and &ldquo;e-ISSN: 1234-5678&rdquo; etc, but there are still lots of invalid ones which need more manual work:
<ul>
<li>Too few characters</li>
<li>Too many characters</li>
<li>ISBNs</li>
</ul>
</li>
<li>Create the CGSpace community and collection structure for the new Accelerating Impacts of CGIAR Climate Research for Africa (AICCRA) and assign all workflow steps</li>
</ul>
<h2 id="2021-04-04-1">2021-04-04</h2>
<ul>
<li>The AReS Explorer harvesting from yesterday finished, and the results look OK, but actually the Elasticsearch indexes are messed up again:</li>
</ul>
<pre><code class="language-console" data-lang="console">$ curl -s 'http://localhost:9200/_alias/' | python -m json.tool
{
&quot;openrxv-items-final&quot;: {
&quot;aliases&quot;: {}
},
&quot;openrxv-items-temp&quot;: {
&quot;aliases&quot;: {
&quot;openrxv-items&quot;: {}
}
},
...
}
</code></pre><ul>
<li><code>openrxv-items</code> should be an alias of <code>openrxv-items-final</code>, not <code>openrxv-temp</code>&hellip; I will have to fix that manually</li>
<li>Enrico asked for more information on the RTB stats I gave him yesterday
<ul>
<li>I remembered (again) that we can&rsquo;t filter Atmire&rsquo;s CUA stats by date issued</li>
<li>To show, for example, views/downloads in the year 2020 for RTB issued in 2020, we would need to use the DSpace statistics API and post a list of IDs and a custom date range</li>
<li>I tried to do that here by exporting the RTB community and extracting the IDs for items issued in 2020:</li>
</ul>
</li>
</ul>
<pre><code class="language-console" data-lang="console">$ ~/dspace63/bin/dspace metadata-export -i 10568/80100 -f /tmp/rtb.csv
$ csvcut -c 'id,dcterms.issued,dcterms.issued[],dcterms.issued[en_US]' /tmp/rtb.csv | \
sed '1d' | \
csvsql --no-header --no-inference --query 'SELECT a AS id,COALESCE(b, &quot;&quot;)||COALESCE(c, &quot;&quot;)||COALESCE(d, &quot;&quot;) AS issued FROM stdin' | \
csvgrep -c issued -m 2020 | \
csvcut -c id | \
sed '1d' | \
sort | \
uniq
</code></pre><ul>
<li>So I remember in the future, this basically does the following:
<ul>
<li>Use csvcut to extract the id and all date issued columns from the CSV</li>
<li>Use sed to remove the header so we can refer to the columns using default a, b, c instead of their real names (which are tricky to match due to special characters)</li>
<li>Use csvsql to concatenate the various date issued columns (coalescing where null)</li>
<li>Use csvgrep to filter items by date issued in 2020</li>
<li>Use csvcut to extract the id column</li>
<li>Use sed to delete the header row</li>
<li>Use sort and uniq to filter out any duplicate IDs (there were three)</li>
</ul>
</li>
<li>Then I have a list of 296 IDs for RTB items issued in 2020</li>
<li>I constructed a JSON file to post to the DSpace Statistics API:</li>
</ul>
