|
<li>Looking at some DAGRIS data for Abenet Yabowork</li>
|
||
|
|
<li>Lots of issues with spaces, newlines, etc causing the import to fail</li>
|
||
|
|
<li>I noticed we have a very <em>interesting</em> list of countries on CGSpace:</li>
|
||
|

|

|
|
|
||
|
|
<ul>
|
||
|
|
<li>Not only are there 49,000 countries, we have some blanks (25)…</li>
|
||
|
|
<li>Also, lots of things like “COTE D`LVOIRE” and “COTE D IVOIRE”</li>

|
|
<ul>
|
||
|
|
<li>Found a way to get items with null/empty metadata values from SQL</li>
|
||
|
|
<li>First, find the <code>metadata_field_id</code> for the field you want from the <code>metadatafieldregistry</code> table:</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>dspacetest=# select * from metadatafieldregistry;
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>In this case our country field is 78</li>
|
||
|
|
<li>Now find all resources with type 2 (item) that have null/empty values for that field:</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>dspacetest=# select resource_id from metadatavalue where resource_type_id=2 and metadata_field_id=78 and (text_value='' OR text_value IS NULL);
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>Then you can find the handle that owns it from its <code>resource_id</code>:</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>dspacetest=# select handle from item, handle where handle.resource_id = item.item_id AND item.item_id = '22678';
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>It’s 25 items so editing in the web UI is annoying, let’s try SQL!</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>dspacetest=# delete from metadatavalue where metadata_field_id=78 and text_value='';
|
||
|
|
DELETE 25
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>After that perhaps a regular <code>dspace index-discovery</code> (no -b) <em>should</em> suffice…</li>
|
||
|
|
<li>Hmm, I indexed, cleared the Cocoon cache, and restarted Tomcat but the 25 “|||” countries are still there</li>
|
||
|
|
<li>Maybe I need to do a full re-index…</li>
|
||
|
|
<li>Yep! The full re-index seems to work.</li>
|
||
|
|
<li>Process the empty countries on CGSpace</li>
|
||
|

<ul>
|
||
|
|
<li>Working on cleaning up Abenet’s DAGRIS data with OpenRefine</li>
|
||
|
|
<li>I discovered two really nice functions in OpenRefine: <code>value.trim()</code> and <code>value.escape("javascript")</code> which shows whitespace characters like <code>\r\n</code>!</li>
|
||
|
|
<li>For some reason when you import an Excel file into OpenRefine it exports dates like 1949 to 1949.0 in the CSV</li>
|
||
|
|
<li>I re-import the resulting CSV and run a GREL on the date issued column: <code>value.replace("\.0", "")</code></li>
|
||
|
|
<li>I need to start running DSpace in Mac OS X instead of a Linux VM</li>
|
||
|
|
<li>Install PostgreSQL from homebrew and configure:</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>$ postgres -D /opt/brew/var/postgres
|
||
|
|
$ createuser --pwprompt dspacetest
|
||
|
|
$ createdb -O dspacetest --encoding=UNICODE dspacetest
|
||
|
|
</code></pre>
|
||
|
|
|
||
|
|
<ul>
|
||
|
|
<li>After building and running a <code>fresh_install</code> I symlinked the webapps into Tomcat’s webapps folder:</li>
|
||
|
|
</ul>
|
||
|
|
|
||
|
|
<pre><code>$ mv /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/ROOT /opt/brew/Cellar/tomcat/8.0.30/libexec/webapps/ROOT.orig

<li>Add CATALINA_OPTS in <code>/opt/brew/Cellar/tomcat/8.0.30/libexec/bin/setenv.sh</code>, as this script is sourced by the <code>catalina</code> startup script</li>
