+- The `fix-metadata.py` script I have is meant for specific metadata values, so if I want to update some `text_lang` values I should just do it directly in the database
+- For example, on a limited set:
+
+```
+dspace=# update metadatavalue set text_lang=NULL where resource_type_id=2 and metadata_field_id=203 and text_value='LIVESTOCK' and text_lang='';
+UPDATE 420

+- Not sure what's going on, but Discovery shows 83 values, and database shows 85, so I'm going to reindex Discovery just in case
