<li>Looking at the CG Core document again, I’ll send some feedback to Peter and Abenet:
|
|
|
|
<ul>
|
|
<li>We use cg.contributor.crp to indicate the CRP(s) affiliated with the item</li>
|
|
<li>DSpace has dc.date.available, but this field isn’t particularly meaningful other than as an automatic timestamp at the time of item accession (and is identical to dc.date.accessioned)</li>
|
|
<li>dc.relation exists in CGSpace, but isn’t used—rather dc.relation.ispartofseries, which is used ~5,000 times to Series name and number within that series</li>
|
|
</ul></li>
|
|
<li>Also, I’m noticing some weird outliers in <code>cg.coverage.region</code>, need to remember to go correct these later:</li>
|
|
</ul>
|

<li>Trying to find a way to get the number of items submitted by a certain user in 2016</li>

<li>It’s not possible in the DSpace search / module interfaces, but might be able to be derived from <code>dc.description.provenance</code>, as that field contains the name and email of the submitter/approver, ie:</li>

<ul>
|

<li>This SQL query returns fields that were submitted or approved by giampieri in 2016 and contain a “checksum” (ie, there was a bitstream in the submission):</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# select * from metadatavalue where resource_type_id=2 and metadata_field_id=28 and text_value ~ '^(Submitted|Approved).*giampieri.*2016-.*checksum.*';

</code></pre>
|
|

<ul>

<li>Then this one does the same, but for fields that don’t contain checksums (ie, there was no bitstream in the submission):</li>

<pre><code>dspace=# select * from metadatavalue where resource_type_id=2 and metadata_field_id=28 and text_value ~ '^(Submitted|Approved).*giampieri.*2016-.*' and text_value !~ '^(Submitted|Approved).*giampieri.*2016-.*checksum.*';

|
|
<li>For some reason there seem to be way too many fields, for example there are 498 + 13 here, which is 511 items for just this one user.</li>
|
|
<li>It looks like there can be a scenario where the user submitted AND approved it, so some records might be doubled…</li>
|
|
<li>In that case it might just be better to see how many the user submitted (both <em>with</em> and <em>without</em> bitstreams):</li>

<li>After reading the <a href="https://wiki.duraspace.org/display/cmtygp/DCAT+Meeting+April+2017">notes for DCAT April 2017</a> I am testing some new settings for PostgreSQL on DSpace Test:
|
|
|
|
<ul>
|
|
<li><code>db.maxconnections</code> 30→70 (the default PostgreSQL config allows 100 connections, so DSpace’s default of 30 is quite low)</li>
|
|
<li><code>db.maxwait</code> 5000→10000</li>
|
|
<li><code>db.maxidle</code> 8→20 (DSpace default is -1, unlimited, but we had set it to 8 earlier)</li>
|
|
</ul></li>
|
|
<li>I need to look at the Munin graphs after a few days to see if the load has changed</li>
|
|
<li>Run system updates on DSpace Test and reboot the server</li>
|
|
<li>Discussing harvesting CIFOR’s DSpace via OAI</li>
|
|
<li>Sisay added their OAI as a source to a new collection, but using the Simple Dublin Core method, so many fields are unqualified and duplicated</li>
|
|
<li>Looking at the <a href="https://wiki.duraspace.org/display/DSDOC5x/XMLUI+Configuration+and+Customization">documentation</a> it seems that we probably want to be using DSpace Intermediate Metadata</li>

<ul>
|
|
<li>Adjust Linode CPU usage alerts on DSpace servers
|
|
|
|
<ul>
|
|
<li>CGSpace from 200 to 250%</li>
|
|
<li>DSpace Test from 100 to 150%</li>
|
|
</ul></li>
|
|
<li>Remove James from Linode access</li>
|
|
<li>Look into having CIFOR use a sub prefix of 10568 like 10568.01</li>
|
|
<li>Handle.net calls this <a href="https://www.handle.net/faq.html#4">“derived prefixes”</a> and it seems this would work with DSpace if we wanted to go that route</li>
