- Looking at some DAGRIS data for Abenet Yabowork
- Lots of issues with spaces, newlines, etc causing the import to fail
- I noticed we have a very *interesting* list of countries on CGSpace:

![CGSpace country list](../images/2016/02/cgspace-countries.png)

- Not only are there 49,000 countries, we have some blanks (25)...
- Also, lots of things like "COTE D`LVOIRE" and "COTE D IVOIRE"

- Found a way to get items with null/empty metadata values from SQL
- First, find the `metadata_field_id` for the field you want from the `metadatafieldregistry` table:

```
dspacetest=# select * from metadatafieldregistry;
```

- In this case our country field is 78
- Now find all resources with type 2 (item) that have null/empty values for that field:

```
dspacetest=# select resource_id from metadatavalue where resource_type_id=2 and metadata_field_id=78 and (text_value='' OR text_value IS NULL);
```

- Then you can find the handle that owns it from its `resource_id`:

```
dspacetest=# select handle from item, handle where handle.resource_id = item.item_id AND item.item_id = '22678';
```

- It's 25 items so editing in the web UI is annoying, let's try SQL!

```
dspacetest=# delete from metadatavalue where metadata_field_id=78 and text_value='';
DELETE 25
```

- After that perhaps a regular `dspace index-discovery` (no -b) *should* suffice...
- Hmm, I indexed, cleared the Cocoon cache, and restarted Tomcat but the 25 "|||" countries are still there
- Maybe I need to do a full re-index...
- Yep! The full re-index seems to work.
