There appears to be a pattern but I’ll have to look a bit closer and try to clean them up automatically, either in SQL or in OpenRefine

<li>Peter Ballantyne said he was having problems logging into CGSpace with “both” of his accounts (CGIAR LDAP and personal, apparently)</li>

<li>I looked in the logs and saw some LDAP lookup failures due to timeout but also strangely a “no DN found” error:</li>

<li>I thought maybe his account had expired (seeing as it’s was the first of the month) but he says he was finally able to log in today</li>

<li>For what it’s worth, there are no errors on any other recent days, so it must have been some network issue on Linode or CGNET’s LDAP server</li>

<li>Linode emailed to say that linode578611 (DSpace Test) needs to migrate to a new host for a security update so I initiated the migration immediately rather than waiting for the scheduled time in two weeks</li>

<li>Twice in the last twenty-four hours Linode has alerted about high CPU usage on CGSpace (linode2533629)</li>
|
|
<li>Communicate with Sam from the CGIAR System Organization about some broken links coming from their CGIAR Library domain to CGSpace</li>
|
|
<li>The first is a link to a browse page that should be handled better in nginx:</li>
|
|
</ul>
|

<pre><code>http://library.cgiar.org/browse?value=Intellectual%20Assets%20Reports&type=subject → https://cgspace.cgiar.org/browse?value=Intellectual%20Assets%20Reports&type=subject

|
</code></pre>
|
|
|
|
<ul>
|
|
<li>We’ll need to check for browse links and handle them properly, including swapping the <code>subject</code> parameter for <code>systemsubject</code> (which doesn’t exist in Discovery yet, but we’ll need to add it) as we have moved their poorly curated subjects from <code>dc.subject</code> to <code>cg.subject.system</code></li>
|
|
<li>The second link was a direct link to a bitstream which has broken due to the sequence being updated, so I told him he should link to the handle of the item instead</li>
|
|
<li>Help Sisay proof sixty-two IITA records on DSpace Test</li>
|
|
<li>Lots of inconsistencies and errors in subjects, dc.format.extent, regions, countries</li>

<li>Merge the Discovery search changes for ISI Journal (<a href="https://github.com/ilri/DSpace/pull/341">#341</a>)</li>

<li>Working on the nginx redirects for CGIAR Library</li>
|
|
<li>We should start using 301 redirects and also allow for <code>/sitemap</code> to work on the library.cgiar.org domain so the CGIAR System Organization people can update their Google Search Console and allow Google to find their content in a structured way</li>
|
|
<li>Remove eleven occurrences of <code>ACP</code> in IITA’s <code>cg.coverage.region</code> using the Atmire batch edit module from Discovery</li>
|
|
<li>Need to investigate how we can verify the library.cgiar.org using the HTML or DNS methods</li>
|
|
<li>Run corrections on 143 ILRI Archive items that had two <code>dc.identifier.uri</code> values (Handle) that Peter had pointed out earlier this week</li>
|
|
<li>I used OpenRefine to isolate them and then fixed and re-imported them into CGSpace</li>
|
|
<li>I manually checked a dozen of them and it appeared that the correct handle was always the second one, so I just deleted the first one</li>
