<ul>
<li>Spent more time looking at the ImageMagick CMYK issue</li>
<li>The <code>default_cmyk.icc</code> and <code>default_rgb.icc</code> files are both part of the Ghostscript GPL distribution, but according to DSpace&rsquo;s <code>LICENSES_THIRD_PARTY</code> file, DSpace doesn&rsquo;t allow distribution of dependencies that are licensed solely under the GPL</li>
<li>So this issue is kinda pointless now, as the ICC profiles are absolutely necessary to make a meaningful CMYK→sRGB conversion</li>

<li>But there are hundreds of combinations of fields and values (like <code>dc.subject</code> and all the center subjects), and we can&rsquo;t use wildcards in REST!</li>
<li>Reading about enabling multiple handle prefixes in DSpace</li>
<li>There is a mailing list thread from 2011 about it: <a href="http://dspace.2283337.n4.nabble.com/Multiple-handle-prefixes-merged-DSpace-instances-td3427192.html">http://dspace.2283337.n4.nabble.com/Multiple-handle-prefixes-merged-DSpace-instances-td3427192.html</a></li>
<li>And a comment from Atmire&rsquo;s Bram about it on the DSpace wiki: <a href="https://wiki.duraspace.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296">https://wiki.duraspace.org/display/DSDOC5x/Installing+DSpace?focusedCommentId=78163296#comment-78163296</a></li>
<li>Bram mentions an undocumented configuration option <code>handle.plugin.checknameauthority</code>, but I noticed another one in <code>dspace.cfg</code>:</li>
</ul>
<pre><code># List any additional prefixes that need to be managed by this handle server
# (as for examle handle prefix coming from old dspace repository merged in
# that repository)
# handle.additional.prefixes = prefix1[, prefix2]
</code></pre>
<ul>
<li>Because of this I noticed that our Handle server&rsquo;s <code>config.dct</code> was potentially misconfigured!</li>
<li>We had some default values still present:</li>
</ul>
<pre><code>&quot;300:0.NA/YOUR_NAMING_AUTHORITY&quot;
</code></pre>
<ul>
<li>I&rsquo;ve changed them to the following and restarted the handle server:</li>
</ul>
<pre><code>&quot;300:0.NA/10568&quot;
</code></pre>
<ul>
<li>In looking at all the configs I just noticed that we are not providing a DOI in the Google-specific metadata crosswalk</li>
<li>From <code>dspace/config/crosswalks/google-metadata.properties</code>:</li>
</ul>
<pre><code>google.citation_doi = cg.identifier.doi
</code></pre>
<ul>
<li>This works, and makes DSpace output the following metadata on the item view page:</li>
</ul>
<pre><code>&lt;meta content=&quot;https://dx.doi.org/10.1186/s13059-017-1153-y&quot; name=&quot;citation_doi&quot;&gt;
