+- Still discussing dates with IWMI
+- I looked in the database to see the breakdown of date formats used in `dc.date.issued`, ie YYYY, YYYY-MM, or YYYY-MM-DD:

+```
+dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=15 and text_value ~ '^[0-9]{4}$';
+ count
+-------
+ 53292
+(1 row)
+dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=15 and text_value ~ '^[0-9]{4}-[0-9]{2}$';
+ count

+dspace=# select count(text_value) from metadatavalue where resource_type_id=2 and metadata_field_id=15 and text_value ~ '^[0-9]{4}-[0-9]{2}-[0-9]{2}$';
+ count

+ 17357
