+- Experimenting with moving some of my Python scripts to the DSpace 7 REST API
+  - I need a way to get UUIDs for Handles...
+  - Seems that I can use a Discovery query like: https://dspace7test.ilri.org/server/api/discover/search/objects?dsoType=item&query=handle:10568/130864
+  - Then just take the first result...?
+- I spent some time working on the script get abstracts from CGSpace, and found a bug in my logic
+  - I also noticed that one item had two abstracts, but the first one was blank!
+  - Looking deeper, I found 113 blank metadata values so I deleted those:
+
+```sql
+BEGIN;
+DELETE FROM metadatavalue WHERE dspace_object_id IN (SELECT uuid FROM item) AND text_value='';
+COMMIT;
+```
+
+- I also found a few dozen items with "N/A" for their citation, so I deleted those too:
+
+```sql
+BEGIN;
+DELETE FROM metadatavalue WHERE dspace_object_id IN (SELECT uuid FROM item) AND text_value='N/A' AND metadata_field_id=146;
+COMMIT;
+```
