<ul>
<li>Linode sent an alert that CGSpace (linode18) was using 350% CPU for the past two hours</li>
<li>I looked in the Activity pane of the Admin Control Panel and it seems that Google, Baidu, Yahoo, and Bing are all crawling with massive numbers of bots concurrently (~100 total, mostly Baidu and Google)</li>
<li>The good thing is that, according to <code>dspace.log.2017-08-01</code>, they are all using the same Tomcat session</li>
<li>This means our Tomcat Crawler Session Valve is working</li>
<li>But many of the bots are browsing dynamic URLs like:
<ul>
<li>/handle/10568/3353/discover</li>
<li>/handle/10568/16510/browse</li>
</ul>
</li>
<li>The <code>robots.txt</code> only blocks the top-level <code>/discover</code> and <code>/browse</code> URLs&hellip; we will need to find a way to forbid them from accessing these!</li>
<li>Relevant issue from DSpace Jira (semi resolved in DSpace 6.0): <a href="https://jira.duraspace.org/browse/DS-2962">https://jira.duraspace.org/browse/DS-2962</a></li>
<li>It turns out that we&rsquo;re already adding the <code>X-Robots-Tag &quot;none&quot;</code> HTTP header, but this only forbids the search engine from <em>indexing</em> the page, not crawling it!</li>
<li>Also, the bot has to successfully browse the page first so it can receive the HTTP header&hellip;</li>
<li>We might actually have to <em>block</em> these requests with HTTP 403 depending on the user agent</li>
<li>Abenet pointed out that the CGIAR Library Historical Archive collection I sent July 20th only had ~100 entries, instead of 2415</li>
<li>This was due to newline characters in the <code>dc.description.abstract</code> column, which caused OpenRefine to choke when exporting the CSV</li>
<li>I exported a new CSV from the collection on DSpace Test and then manually removed the characters in vim using <code>g/^$/d</code></li>
<li>Then I cleaned up the author authorities and HTML characters in OpenRefine and sent the file back to Abenet</li>
</ul>

<li>Testing adding <a href="https://wiki.lyrasis.org/display/DSDOC5x/ORCID+Integration#ORCIDIntegration-EditingexistingitemsusingBatchCSVEditing">ORCIDs to a CSV</a> file for a single item to see if the author orders get messed up</li>
<li>Need to test the following scenarios to see how author order is affected:
<ul>
<li>ORCIDs only</li>
<li>ORCIDs plus normal authors</li>
</ul>

<li>I exported a random item&rsquo;s metadata as CSV, deleted <em>all columns</em> except id and collection, and made a new coloum called <code>ORCID:dc.contributor.author</code> with the following random ORCIDs from the ORCID registry:</li>
