<li>I tried to clean up the duplicate mappings by exporting the item’s metadata to CSV, editing, and re-importing, but DSpace said “no changes were detected”</li>
|
|
<li>I’ve asked on the dspace-tech mailing list to see if anyone can help</li>
|
|
<li>I found an old post on the mailing list discussing a similar issue, and listing some SQL commands that might help</li>
|
|
<li>For example, this shows 186 mappings for the item, the first three of which are real:</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# select * from collection2item where item_id = '80596';
|
|
</code></pre>
|
|
|
|
<ul>
|

<li>Then I deleted the others:</li>
|
|
</ul>
|
|
|
|
<pre><code>dspace=# delete from collection2item where item_id = '80596' and id not in (90792, 90806, 90807);
|
|
</code></pre>
|
|
|
|
<ul>
|
|
<li>And in the item view it now shows the correct mappings</li>
|
|
<li>I will have to ask the DSpace people if this is a valid approach</li>
|
|
<li>Finish looking at the Journal Title corrections of the top 500 Journal Titles so we can make a controlled vocabulary from it</li>
