<li>Discuss new “final” CG Core document and some changes that we’ll need to do on CGSpace and other repositories</li>
|
|
<li>We agreed to try to stick to pure Dublin Core where possible, then use fields that exist in standard DSpace, and use “cg” namespace for everything else</li>

<li>Major changes are to move <code>dc.contributor.author</code> to <code>dc.creator</code> (which MELSpace and WorldFish are already using in their DSpace repositories)</li>

<li>I am testing the speed of the WorldFish DSpace repository’s REST API and it’s five to ten times faster than CGSpace as I tested in <a href="/cgspace-notes/2018-10/">2018-10</a>:</li>

<li>Trying to decide the solid action points for CGSpace on the CG Core 2.0 metadata…</li>
|
|
<li>It’s difficult to decide some of these because the current CG Core 2.0 document does not provide guidance or rationale (yet)!</li>
|
|
<li>Also, there is not a good Dublin Core reference (or maybe I just don’t understand?)</li>
|
|
<li>Several authoritative documents on Dublin Core appear to be:
|
|
|
|
<ul>
|
|
<li><a href="http://dublincore.org/documents/dces/">Dublin Core Metadata Element Set, Version 1.1: Reference Description</a></li>
|
|
<li><a href="http://www.dublincore.org/documents/dcmi-terms/">DCMI Metadata Terms</a></li>
|
|
</ul></li>
|
|
<li>And what is the relationship between DC and DCTERMS?</li>
|
|
<li>DSpace uses DCTERMS in the metadata it embeds in XMLUI item views!</li>
|
|
<li>We really need to look at this more carefully and see the impacts that might be made from switching core fields like languages, abstract, authors, etc</li>
|
|
<li>We can check WorldFish and MELSpace repositories to see what effects these changes have had on theirs because they have already adopted some of these changes…</li>
|
|
<li>I think I understand the difference between DC and DCTERMS finally: DC is the original set of fifteen elements and DCTERMS is the newer version that was supposed to address much of the drawbacks of the original with regards to digital content</li>
|
|
<li>We might be able to use some proper fields for citation, abstract, etc that are part of DCTERMS</li>
|
|
<li>To make matters more confusing, there is also “qualified Dublin Core” that uses the original fifteen elements of legacy DC and qualifies them, like <code>dc.date.accessioned</code>
|
|
|
|
<ul>
|
|
<li>According to Wikipedia <a href="https://en.wikipedia.org/wiki/Dublin_Core">Qualified Dublin Core was superseded by DCTERMS in 2008</a>!</li>
|
|
</ul></li>
|
|
<li>So we should be trying to use DCTERMS where possible, unless it is some internal thing that might mess up DSpace (like dates)</li>
|
|
<li>“Elements 1.1” means legacy DC</li>
|
|
<li>Possible action list for CGSpace:
|
|
|
|
<ul>
|
|
<li>dc.description.abstract → dcterms.abstract</li>
|
|
<li>dc.description.version → cg.peer-reviewed (or cg.peer-review-status?)</li>
|
|
<li>dc.description.sponsorship → cg.contributor.donor</li>
|
|
<li>dc.contributor.author → dc.creator</li>
|
|
<li>dc.language.iso → dcterms.language</li>
|
|
<li>cg.identifier.url → dcterms.identifier</li>
|
|
<li>dc.identifier.citation → dcterms.bibliographicCitation</li>
|
|
<li>dc.relation.ispartofseries → dcterms.isPartOf</li>

<li>cg.targetaudience → dcterms.audience</li>

<li>There’s no official set of Dublin Core qualifiers so I can’t tell if things like <code>dc.contributor.author</code> that are used by DSpace are official</li>
|
|
<li>I found a great <a href="https://www.dri.ie/sites/default/files/files/qualified-dublin-core-metadata-guidelines.pdf">presentation from 2015 by the Digital Repository of Ireland</a> that discusses using MARC Relator Terms with Dublin Core elements</li>
|
|
<li>It seems that <code>dc.contributor.author</code> would be a supported term according to this <a href="https://memory.loc.gov/diglib/loc.terms/relators/dc-contributor.html">Library of Congress list</a> linked from the <a href="http://dublincore.org/usage/documents/relators/">Dublin Core website</a></li>
|
|
<li>The Library of Congress document specifically says:</li>
|
|
</ul>
|
|
|
|
<p>These terms conform with the DCMI Abstract Model and may be used in DCMI application profiles. DCMI endorses their use with Dublin Core elements as indicated.</p>

<li><p>Apparently Google announced last year that they plan to <a href="https://developers.googleblog.com/2018/03/transitioning-google-url-shortener.html">discontinue the shortner and transition to Firebase Dynamic Links in March, 2019</a>, so maybe this is related…</p></li>

<li><p>Very interesting discussion of methods for <a href="https://jdebp.eu/FGA/systemd-house-of-horror/tomcat.html">running Tomcat under systemd</a></p></li>
|
|
|
|
<li><p>We can set the ulimit options that used to be in <code>/etc/default/tomcat7</code> with systemd’s <code>LimitNOFILE</code> and <code>LimitAS</code> (see the <code>systemd.exec</code> man page)</p>

<ul>
|
|
<li>Note that we need to use <code>infinity</code> instead of <code>unlimited</code> for the address space</li>
