 - This worked very well, but there were some metadata values that were tripled or quadrupled, so it only deleted the first duplicate
   - I just ran it again two more times to find the last duplicates, now we have none!
+- I also generated another SQL file with commands to update the last modified timestamps of these items:
+
+```console
+$ awk -F'\t' '{print $4}' /tmp/duplicates.txt | sort -u | sed "s/^\(.*\)$/UPDATE item SET last_modified=NOW() WHERE uuid='\1';/" > /tmp/update-timestamp.sql

+- The timing looks suspiciously close to when I was running the batch updates on the ILRI community this morning.
+  - I restarted Tomcat and PostgreSQL and everything was back to normal
+- I found some items on CGSpace in Dinka, Ndogo, and Bari languages, but the `dcterms.language` field was "other"
+  - That's so unfortunate! These languages are not in ISO 639-1, but they are in ISO 639-3, which uses Alpha 3 and has more space for languages
+  - I changed them from other to use the three-letter codes, and I will suggest to the CG Core group that we use ISO 639-3 in the future
