 - Seems to work fine!
+- I noticed a few items that have incorrect DOI links (`dc.identifier.doi`), and after looking in the database I see there are over 100 that are missing the scheme or are just plain wrong:
+
+```
+dspace=# select distinct text_value from metadatavalue where resource_type_id=2 and metadata_field_id=220 and text_value not like 'http%://%';
+```
+
+- This will replace any that begin with `10.`:
+
+```
+dspace=# update metadatavalue set text_value = regexp_replace(text_value, '(^10\..+$)', 'https://dx.doi.org/\1') where metadata_field_id IN (select metadata_field_id from metadatafieldregistry where element = 'identifier' and qualifier = 'doi') and text_value like '10.%';
+```
