Please pay attention to configure the property DATACITE_HOST. Per default it is set to the DataCite test server. To reserve real DOIs you will probably have to change it to mds.datacite.org. Ask your registration agency if you're not sure about the correct address. Unfortunately

...

  For the test server you have to set the DATACITE_DOI_PATH to "/mds/doi/" and the DATACITE_METADATA_PATH  to "/mds/doi/", for the production server you have to remove the leading /mds from both properties.

DSpace should send updates to DataCite whenever the metadata of an item changes. To do so you have to change the dspace.cfg again. You should remove the comments in front of the two following properties or add them to the dspace.cfg:

...

The command line interface in general is documented here: Command Line Operations.

The command used for DOIs is 'doi-organiser'. You can use the following options:

...

# Send information about new and changed DOIs to the DOI registration agency:
0 1,13 * * *  [dspace]/bin/dspace doi-organiser -u -q ; [dspace]/bin/dspace doi-organiser -s -q ; [dspace]/bin/dspace doi-organiser -r -q ; [dspace]/bin/dspace doi-organiser -d -q

Limitations of DataCite DOI support

That means if you want to use other applications or even more than one DSpace installation to register DOIs with the same prefix, you'll have to use a unique namespace separator for each of them. Also you should not generate DOIs manually with the same prefix and namespace separator you configured within DSpace. For example, if your prefix is 10.5072 you can configure one DSpace installation to generate DOIs starting with 10.5072/papers-, a second installation to generate DOIs starting with 10.5072/data- and another application to generate DOIs starting with 10.5072/results-.

DOIs will be used in addtion addition to Handles. This implementation does not replace Handles with DOIs in DSpace. That means that DSpace will still continue to generate Handles for every item, every collection and every community, and will use those Handles as part of the URL of items, collections and communities.

DSpace currently generates DOIs for items only. There is no support to generate DOIs for Communities and collections yet.

When using DSpaces DSpace's support for the DataCite API probably not all infomration information would be restored when using the AIP Backup and Restore (see

...

The EZID IdentifierProvider operates synchronously, so there is much less to configure. You will need to un-comment the the org.dspace.identifier.EZIDIdentifierProvider bean in config/spring/api/identifier-service.xml to enable DOI registration through EZID.

...

In Back in config/spring/api/identifier-service.xml you will see some other configuration of the EZIDIdentiferProvider bean.  You may not need to change any of it.  But here you can alter the mapping between DSpace and EZID metadata, should you choose.  The crosswalk property is a map from DSpace metadata fields to EZID fields, and can be extended or changed.  The key of each entry is the name of an EZID metadata field; the value is the name of the corresponding DSpace field, from which the EZID metadata will be populated.

You can also supply transformations to be applied to field values using the crosswalkTransform property.  Each key is the name of an EZID metadata field, and its value is the name of a Java class which will convert the value of the corresponding DSpace field to its EZID form.  The only transformation currently provided is one which converts a date to the year of that date, named org.dspace.identifier.ezid.DateToYear.  In the configuration as delivered, it is used to convert the date of issue to the year of publication.  You may create new Java classes with which to supply other transformations, and map them to metadata fields here.  If an EZID metadatum is not named in this map, the default mapping is applied:  the string value of the DSpace field is copied verbatim.

. In most situations, the default settings should work well.  But, here's an explanation of options available:

• EZID Provider / Registrar settings: By default, the EZIDIdentifierProvider is configured to use the CDLib provider (ezid.cdlib.org) in the EZID_SCHEME, EZID_HOST and EZID_PATH settings. In most situations, the default values should work for you. However, you may need to modify these values (especially the EZID_HOST) if you are registered with a different EZID provider. In that situation, please check with your provider for valid "host" and "path" settings. If your provider provides EZID service at a particular path on its host, you may set that in EZID_PATH.
  
  • NOTE: As of the writing of this documentation, the default CDLib provider settings should also work for institutions that use Purdue (ezid.lib.purdue.edu) as a provider. Currently, Purdue and CDLib currently share the same infrastructure, and both ezid.cdlib.org and ezid.lib.purdue.edu point to the same location.
    
• Metadata mappings: You can alter the mapping between DSpace and EZID metadata, should you choose.  The crosswalk property is a map from DSpace metadata fields to EZID fields, and can be extended or changed.  The key of each entry is the name of an EZID metadata field; the value is the name of the corresponding DSpace field, from which the EZID metadata will be populated.
• Crosswalking / Transforms: You can also supply transformations to be applied to field values using the crosswalkTransform property.  Each key is the name of an EZID metadata field, and its value is the name of a Java class which will convert the value of the corresponding DSpace field to its EZID form. The only transformation currently provided is one which converts a date to the year of that date, named org.dspace.identifier.ezid.DateToYear.  In the configuration as delivered, it is used to convert the date of issue to the year of publication.  You may create new Java classes with which to supply other transformations, and map them to metadata fields here.  If an EZID metadatum is not named in this map, the default mapping is applied:  the string value of the DSpace field is copied verbatim.

Limitations of EZID DOI support

DOIs will be used in addition to Handles. This implementation does not replace Handles with DOIs in DSpace. That means that DSpace will continue to generate Handles for every item, every collection and every community, and will use those Handles as part of the URL of items, collections and communities.

Currently, the EZIDIdentifierProvider has a known issue where it stores its DOIs in the dc.identifier field, instead of using the dc.identifier.uri field (which is the one used by DataCite DOIs and Handles).  See DS-2199 for more details. This will be corrected in a future version of DSpace.

DSpace currently generates DOIs for items only. There is no support to generate DOIs for Communities and Collections yetNormally, you should not change the value of the EZID_SCHEME property of the EZIDRequestFactory bean.  If you registered with the CDLib provider, you should not change the value of EZID_HOST; if you registered with another provider, such as Purdue, you should set the EZID_HOST appropriately (for example, https://ezid.lib.purdue.edu).  If your provider provides EZID service at a particular path on its host, you may set that in EZID_PATH.
