Linode has alerted a few times since last night that the CPU usage on CGSpace (linode18) was high despite me increasing the alert threshold last week from 250% to 275%—I might need to increase it again!
|
||
The top IPs before, during, and after this latest alert tonight were:
|
||
|
||
# zcat --force /var/log/nginx/*.log /var/log/nginx/*.log.1 | grep -E "01/Feb/2019:(17|18|19|20|21)" | awk '{print $1}' | sort | uniq -c | sort -n | tail -n 10

85.25.237.71 is the “Linguee Bot” that I first saw last month
|
||
The Solr statistics the past few months have been very high and I was wondering if the web server logs also showed an increase
|

There were just over 3 million accesses in the nginx logs last month:

<li>Add my Python- and shell-based metadata workflow helper scripts as well as the environment settings for pipenv to our DSpace repository (<a href="https://github.com/ilri/DSpace/pull/408">#408</a>) so I can track changes and distribute them more formally instead of just keeping them <a href="https://github.com/ilri/DSpace/wiki/Scripts">collected on the wiki</a></li>

<li>I’m still waiting for feedback from IITA whether they actually want to use “SOCIAL SCIENCE & AGRIC BUSINESS” because it is listed as <a href="http://www.iita.org/project-discipline/social-science-and-agribusiness/">“Social Science and Agribusiness”</a> on their website</li>

<li>Also, I think they want to do some mappings of items with existing subjects to these new themes</li>

<li>Totally works… awesome!</li>

<pre><code>$ sudo touch /etc/subuid /etc/subgid

<li>Deploy the Tomcat-7-from-tarball branch on CGSpace (linode18), but first stop the Ubuntu Tomcat 7 and do some basic prep before running the Ansible playbook:</li>

<ul>
|
||
<li>One mispelled authorship type</li>
|
||
<li>A few dozen incorrect inconsistent affiliations (I dumped a list of the top 1500 affiliations and reconciled against it, but it was still a lot of work)</li>
|
||
<li>One issue with smart quotes in countries</li>
|
||
<li>A few IITA subjects with syntax errors</li>
|
||
<li>Some whitespace and consistency issues in sponsorships</li>
|
||
<li>Eight items with invalid ISBN: 0-471-98560-3</li>
|
||
<li>Two incorrectly formatted ISSNs</li>
|

<li>Lots of incorrect values in subjects, but that’s a difficult problem to do in an automated way</li>

|
||
<p>I figured out how to query AGROVOC from OpenRefine using Jython by creating a custom text facet:</p>
|
||
</li>
|
||
</ul>
|
||
<pre><code>import json
|
||
import re
|
||
import urllib
|
||
import urllib2
|
||
|
||
pattern = re.compile('^S[A-Z ]+$')
|
||
if pattern.match(value):
|
||
url = 'http://agrovoc.uniroma2.it/agrovoc/rest/v1/search?query=' + urllib.quote_plus(value) + '&lang=en'
|
||
get = urllib2.urlopen(url)
|
||
data = json.load(get)
|
||
if len(data['results']) == 1:
|
||
return "matched"
|
||
|
||
return "unmatched"
|
||
</code></pre><ul>
|
||
<li>You have to make sure to URL encode the value with <code>quote_plus()</code> and it totally works, but it seems to refresh the facets (and therefore re-query everything) when you select a facet so that makes it basically unusable</li>
|
||
<li>There is a <a href="https://programminghistorian.org/en/lessons/fetch-and-parse-data-with-openrefine#example-2-url-queries-and-parsing-json">good resource discussing OpenRefine, Jython, and web scraping</a></li>
|
||
</ul>
|
||
<h2 id="2019-02-24">2019-02-24</h2>
|
||
<ul>
|
||
<li>I decided to try to validate the AGROVOC subjects in IITA’s recent batch upload by dumping all their terms, checking them in en/es/fr with <code>agrovoc-lookup.py</code>, then reconciling against the final list using reconcile-csv with OpenRefine</li>
|
||
<li>I’m not sure how to deal with terms like “CORN” that are alternative labels (<code>altLabel</code>) in AGROVOC where the preferred label (<code>prefLabel</code>) would be “MAIZE”</li>
|
||
<li>For example, <a href="http://agrovoc.uniroma2.it/agrovoc/rest/v1/search?query=CORN*&lang=en">a query</a> for <code>CORN*</code> returns:</li>
|
||
</ul>
|
||
<pre><code> "results": [
|
||
{
|
||
"altLabel": "corn (maize)",
|
||
"lang": "en",
|
||
"prefLabel": "maize",
|
||
"type": [
|
||
"skos:Concept"
|
||
],
|
||
"uri": "http://aims.fao.org/aos/agrovoc/c_12332",
|
||
"vocab": "agrovoc"
|
||
},
|
||
</code></pre><ul>
|
||
<li>There are dozens of other entries like “corn (soft wheat)", “corn (zea)", “corn bran”, “Cornales”, etc that could potentially match and to determine if they are related programatically is difficult</li>
|
||
<li>Shit, and then there are terms like “GENETIC DIVERSITY” that should <a href="http://agrovoc.uniroma2.it/agrovoc/agrovoc/en/page/c_33952">technically be</a> “genetic diversity (as resource)”</li>
|
||
<li>I applied all changes to the IITA Feb 14 batch data except the affiliations and sponsorships because I think I made some mistakes with the copying of reconciled values so I will try to look at those again separately</li>
|
||
<li>I went back and re-did the affiliations and sponsorships and then applied them on the IITA Feb 14 collection on DSpace Test</li>
|
||
<li>I did a duplicate check of the IITA Feb 14 records on DSpace Test and there were about fifteen or twenty items reported
|
||
<ul>
|
||
<li>A few of them are actually in previous IITA batch updates, which means they have been uploaded to CGSpace yet, so I worry that there would be many more</li>
|
||
<li>I want to re-synchronize CGSpace to DSpace Test to make sure that the duplicate checking is accurate, but I’m not sure I can because the Earlham guys are still testing COPO actively on DSpace Test</li>
