DOI

Note: The DATACITE_HOST in /config/spring/api/identifier-service.xml is supposed to be mds(.test).datacite.org not api(.test).datacite.org.

Setup Instructions

1. Enable DOI in Event Consumers

In your local.cfg or equivalent config, ensure that doi is included in the event.dispatcher.default.consumers property:

event.dispatcher.default.consumers = ... ,doi

2. Update XSL for Custom Metadata

If you're using custom metadata types (e.g., dc.type = corpus), make sure DIM2DataCite.xsl handles them appropriately. Example from Lindat configuration:

<xsl:when test="$typeValue = 'corpus'">
    <xsl:element name="resourceType">
        <xsl:attribute name="resourceTypeGeneral">Other</xsl:attribute>
        <xsl:value-of select="'corpus'"/>
    </xsl:element>
</xsl:when>

3. Enable DOIIdentifierProvider in Spring Config

Edit [dspace]/config/spring/api/identifier-service.xml and enable the necessary Spring beans:

<bean id="org.dspace.identifier.DOIIdentifierProvider"
      class="org.dspace.identifier.DOIIdentifierProvider"
      scope="singleton">
    <property name="DOIConnector"
              ref="org.dspace.identifier.doi.DOIConnector" />
</bean>

<bean id="org.dspace.identifier.doi.DOIConnector"
   class="org.dspace.identifier.doi.DataCiteConnector"
   scope="singleton">
   <property name='DATACITE_SCHEME' value='https'/>
   <property name='DATACITE_HOST' value='mds.test.datacite.org'/>
   <property name='DATACITE_DOI_PATH' value='/doi/' />
   <property name='DATACITE_METADATA_PATH' value='/metadata/' />
   <property name='disseminationCrosswalkName' value="DataCite" />
</bean>

**Note: **If you want to support versioning, use:

class="org.dspace.identifier.VersionedDOIIdentifierProvider"

4. Configure DOI Credentials and Settings

In local.cfg, add the following configuration with values appropriate to your DOI provider setup:

identifier.doi.user = your-username
identifier.doi.password = your-password
identifier.doi.prefix = 10.xxxx
identifier.doi.namespaceseparator = /

5. Set Up Cronjobs or Scheduled Tasks

To automate the DOI lifecycle, add the following to your crontab or scheduling tool:

[dspace]/bin/dspace doi-organiser -u -q   # Update metadata
[dspace]/bin/dspace doi-organiser -s -q   # Submit reservations
[dspace]/bin/dspace doi-organiser -r -q   # Register DOIs
[dspace]/bin/dspace doi-organiser -d -q   # Deactivate DOIs

Additional Notes

• Pre-registering DOIs (i.e., assigning a DOI before submission) is partially supported. The DOI can be preset, but reservation with the provider might not be triggered automatically.

• If the DOI is properly registered, the pre-assigned DOI will be retained.

• Only an administrator of the item can register its DOI.

• DOI statuses are defined clearly in the official documentation and reflected in the DSpace source code.

• You can monitor or modify DOI states directly in the doi database table.

DOI Workflow Overview

1. Item Creation When a new item is created, a DOI is generated with status TO_BE_RESERVED.

2. Reservation Phase doi-organiser -s reserves DOIs with the registration agency. Status updates to TO_BE_REGISTERED.

3. Registration Phase doi-organiser -r registers the DOI. Status updates to IS_REGISTERED.

4. Finalization Once registered, the DOI appears in the item’s metadata (e.g., under identifier.doi).
