I spent a few days working on a Java-based curation task to tag items with ISO 3166-1 Alpha2 country codes based on their cg.coverage.country text values
|
||
|
|
|
||
|
|
It looks up the names in ISO 3166-1 first, and then in our CGSpace countries mapping (which has five or so of Peter’s preferred “display” country names)
|
||
|
|
It implements a “force” mode too that will clear existing country codes and re-tag everything
|
||
|
|
It is class based so I can easily add support for other vocabularies, and the technique could even be used for organizations with mappings to ROR and Clarisa…

<li>Andrea from Macaroni Bros emailed me a few days ago to say he’s having issues with the CGSpace REST API
|
||
|
|
<ul>
|
||
|
|
<li>He said he noticed the issues when they were developing the WordPress plugin to harvest CGSpace for the RTB website: <a href="https://www.rtb.cgiar.org/publications/">https://www.rtb.cgiar.org/publications/</a></li>

<h2 id="2020-08-04">2020-08-04</h2>
|
||
|
|
<ul>
|
||
|
|
<li>Look into the REST API issues that Macaroni Bros raised last week:
|
||
|
|
<ul>
|
||
|
|
<li>The first one was about the <code>collections</code> endpoint returning empty items:
|
||
|
|
<ul>
|
||
|
|
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=2">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=2</a> (offset=2 is correct)</li>
|
||
|
|
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=3">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=3</a> (offset=3 is empty)</li>
|
||
|
|
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=4">https://cgspace.cgiar.org/rest/collections/1445/items?limit=1&offset=4</a> (offset=4 is correct again)</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>I confirm that the second link returns zero items on CGSpace…
|
||
|
|
<ul>
|
||
|
|
<li>I tested on my local development instance and it returns one item correctly…</li>
|
||
|
|
<li>I tested on DSpace Test (currently DSpace 6 with UUIDs) and it returns one item correctly…</li>
|
||
|
|
<li>Perhaps an indexing issue?</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>The second issue is the <code>collections</code> endpoint returning the wrong number of items:
|
||
|
|
<ul>
|
||
|
|
<li><a href="https://cgspace.cgiar.org/rest/collections/1445">https://cgspace.cgiar.org/rest/collections/1445</a> (numberItems: 63)</li>
|
||
|
|
<li><a href="https://cgspace.cgiar.org/rest/collections/1445/items">https://cgspace.cgiar.org/rest/collections/1445/items</a> (real number of items: 61)</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>I confirm that it is indeed happening on CGSpace…
|
||
|
|
<ul>
|
||
|
|
<li>And actually I can replicate the same issue on my local CGSpace 5.8 instance:</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|

</ul>

<li>Also on DSpace Test (which is running DSpace 6!), though the issue is slightly different there:</li>

||
|

<pre><code>$ http 'https://dspacetest.cgiar.org/rest/collections/5471c3aa-202e-42f0-96c2-497a18e3b708' | json_pp | grep numberItems

|
||
|
|
</code></pre><ul>
|
||
|
|
<li>Ah! I exported that collection’s metadata and checked it in OpenRefine, where I noticed that two items are mapped twice
|
||
|
|
<ul>
|
||
|
|
<li>I dealt with this problem in 2017-01 and the solution is to check the <code>collection2item</code> table:</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|

|
|
</ul>

id | collection_id | item_id

|
||
|
|
(3 rows)
|
||
|
|
</code></pre><ul>
|
||
|
|
<li>So for each id you can delete one duplicate mapping:</li>
|

|

dspace=# DELETE FROM collection2item WHERE id='128819';
|

|
</code></pre><ul>

<li>DSpace itself uses a case-sensitive regex for user agents so there are no hits from those IPs in Solr, but I need to tweak the other regexes so they don’t misuse the resources

<li>Perhaps <code>[Bb][Oo][Tt]</code>…</li>

<li>I see another IP 104.198.96.245, which is also using the “RTB website BOT” but there are 70,000 hits in Solr from earlier this year before they started using the user agent
|

|

<ul>

<li>38.128.66.10 isn’t creating any Solr statistics due to our DSpace agents pattern, but they are creating lots of sessions so perhaps I need to force them to use one session in Tomcat:</li>

<li>I have been working on processing the Solr statistics with the Atmire tool on DSpace Test the last few days:
|
||
|
|
<ul>
|
||
|
|
<li>statistics:
|
||
|
|
<ul>
|
||
|
|
<li>2,040,385 docs: 2h 28m 49s</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>statistics-2019:
|
||
|
|
<ul>
|
||
|
|
<li>8,960,000 docs: 12h 7s</li>
|
||
|
|
<li>1,780,575 docs: 2h 7m 29s</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>statistics-2018:
|
||
|
|
<ul>
|
||
|
|
<li>1,970,000 docs: 12h 1m 28s</li>
|
||
|
|
<li>360,000 docs: 2h 54m 56s (Linode rebooted)</li>
|
||
|
|
<li>1,110,000 docs: 7h 1m 44s (Restarted Tomcat, oops)</li>
|
||
|
|
</ul>

|
</li>

</ul>
|

|

<li>I decided to start the 2018 core over again, so I re-synced it from CGSpace and started again from the solr-upgrade-statistics-6x tool and now I’m having the same issues with Java heap space that I had last month
|
||
|
|
<ul>
|
||
|
|
<li>The process kept crashing due to memory, so I increased the memory to 3072m and finally 4096m…</li>
|
||
|
|
<li>Also, I decided to try to purge all the <code>-unmigrated</code> docs that it had found so far to see if that helps…</li>
|
||
|
|
<li>There were about 466,000 records unmigrated so far, most of which were <code>type: 5</code> (SITE statistics)</li>
|
||
|
|
<li>Now it is processing again…</li>
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
<li>I developed a small Java class called <code>FixJpgJpgThumbnails</code> to remove “.jpg.jpg” thumbnails from the <code>THUMBNAIL</code> bundle and replace them with their originals from the <code>ORIGINAL</code> bundle
|
||
|
|
<ul>
|
||
|
|
<li>The code is based on <a href="https://github.com/UoW-IRRs/DSpace-Scripts/blob/master/src/main/java/nz/ac/waikato/its/irr/scripts/RemovePNGThumbnailsForPDFs.java">RemovePNGThumbnailsForPDFs.java</a> by Andrea Schweer</li>
|
||
|
|
<li>I incorporated it into my dspace-curation-tasks repository, then renamed it to <a href="https://github.com/ilri/cgspace-java-helpers">cgspace-java-helpers</a></li>
|
||
|
|
<li>In testing I found that I can replace ~3,500 thumbnails on CGSpace!</li>
|
||
|
|
</ul>
