There are symbolic constants (and corresponding String symblic names) for the confidence levels defined in the Choices class:
| Confidence | Stored value (in metadatavalue) | Description |
|---|---|---|
| ACCEPTED | 600 | This authority value has been confirmed as accurate by an interactive user or authoritative policy |
| UNCERTAIN | 500 | Authority value is singular and valid but has not been seen and accepted by a human, so its provenance is uncertain |
| AMBIGUOUS | 400 | There are multiple matching authority values of equal validity |
| NOTFOUND | 300 | There are no matching answers from the authority |
| FAILED | 200 | The authority encountered an internal failure in trying to match the value |
| REJECTED | 100 | The authority recommends this submission be rejected |
| NOVALUE | 0 | No reasonable confidence value is available |
| UNUSED | -1 | No confidence value has been set (default value in the DB table) |
Separation of Choices from Authority Control
...
Since choice management and authority control affect the operation of the interactive submission pages, there is naturally some interdependence with that configuration as well. This table shows how the data type chosen for a metadata field affects choice and authority management:
input-type (from input-forms.xml) | 'lookup' Presentation Style | 'suggest' Presentation Style | 'select' Presentation Style | Authority Control |
|---|---|---|---|---|
onebox | yes | yes | yes | supported |
twobox | yes | yes | yes | supported |
textarea | yes | yes | yes | supported |
name | yes | NO | NO | supported |
date | NO | NO | NO | n/a |
series | NO | NO | NO | not tested |
dropdown | NO | NO | yes | NO |
qualdrop_value | NO | NO | NO | NO |
list | NO | NO | ??? | not tested |

plugin.selfnamed.org.dspace.content.authority.ChoiceAuthority = \ org.dspace.content.authority.DCInputAuthority |
Some of the ChoiceAuthority instances available in the default configuration are:

- SRPublisher - Journal Publisher names based on SHERPA/RoMEO database
- SRJournalTitle - Journal Titles based on SHERPA/RoMEO database
- SolrAuthorAuthority - Uses a DSpace Solr index as authority
The org.dspace.content.authority.DCInputAuthority plugin picks up all of the value-pairs tags from the input-forms.xml configuratino and automatically creates plugin instances out of them, named by the name attribute they have in the config. The default DSpace config includes these choice authorities:
