Method Detail

setDATACITE_SCHEME

public void setDATACITE_SCHEME(String DATACITE_SCHEME)

Used to set the scheme to connect the DataCite server. Used by spring dependency injection.

Parameters:

DATACITE_SCHEME - Probably https or http.

setDATACITE_HOST

public void setDATACITE_HOST(String DATACITE_HOST)

Set the hostname of the DataCite server. Used by spring dependency injection.

Parameters:

DATACITE_HOST - Hostname to connect to register DOIs (f.e. test.datacite.org).

setDATACITE_DOI_PATH

public void setDATACITE_DOI_PATH(String DATACITE_DOI_PATH)

Set the path on the DataCite server to register DOIs. Used by spring dependency injection.

Parameters:

DATACITE_DOI_PATH - Path to register DOIs, f.e. /doi.

setDATACITE_METADATA_PATH

public void setDATACITE_METADATA_PATH(String DATACITE_METADATA_PATH)

Set the path to register metadata on DataCite server. Used by spring dependency injection.

Parameters:

DATACITE_METADATA_PATH - Path to register metadata, f.e. /mds.

setConfigurationService

@Autowired
public void setConfigurationService(ConfigurationService configurationService)

setDisseminationCrosswalkName

public void setDisseminationCrosswalkName(String CROSSWALK_NAME)

Set the name of the dissemination crosswalk used to convert the metadata into DataCite Metadata Schema. Used by spring dependency injection.

Parameters:

CROSSWALK_NAME - The name of the dissemination crosswalk to use. This crosswalk must be configured in dspace.cfg.

prepareXwalk

protected void prepareXwalk()

getUsername

protected String getUsername()

getPassword

protected String getPassword()

isDOIReserved

public boolean isDOIReserved(Context context,
                    String doi)
                      throws DOIIdentifierException

Specified by:

isDOIReserved in interface DOIConnector

Throws:

DOIIdentifierException

isDOIReserved

public boolean isDOIReserved(Context context,
                    DSpaceObject dso,
                    String doi)
                      throws DOIIdentifierException

Specified by:

isDOIReserved in interface DOIConnector

Throws:

DOIIdentifierException

isDOIRegistered

public boolean isDOIRegistered(Context context,
                      String doi)
                        throws DOIIdentifierException

Specified by:

isDOIRegistered in interface DOIConnector

Throws:

isDOIRegistered

public boolean isDOIRegistered(Context context,
                      DSpaceObject dso,
                      String doi)
                        throws DOIIdentifierException

Specified by:

isDOIRegistered in interface DOIConnector

Throws:

DOIIdentifierException

deleteDOI

public void deleteDOI(Context context,
             String doi)
               throws DOIIdentifierException

Description copied from interface: DOIConnector

Sends the DELETE-Request to the DOI registry.

This method sends a request to "delete" a DOI. As DOIs are persistent identifiers they should never be deleted. For example, if you send a HTTP DELETE request to the DataCite Metadata API directly, it will set the DOI to inactive.

Specified by:

deleteDOI in interface DOIConnector

Throws:

DOIIdentifierException

reserveDOI

public void reserveDOI(Context context,
              DSpaceObject dso,
              String doi)
                throws DOIIdentifierException

Description copied from interface: DOIConnector

Sends a request to the DOI registry to reserve a DOI. The DOIConnector should check weather this DOI is reserved for another object already. In this case it should throw an DOIIdentifierException and set the error code to DOIIdentifierException.DOI_ALREADY_EXISTS.

Specified by:

reserveDOI in interface DOIConnector

Throws:

DOIIdentifierException

registerDOI

public void registerDOI(Context context,
               DSpaceObject dso,
               String doi)
                 throws DOIIdentifierException

Description copied from interface: DOIConnector

Sends a request to the DOI registry to register a DOI. The DOIConnector ensures compliance with the workflow of the registration agency. For example, if a DOI has to be reserved before it can be registered the DOIConnector has to check if it is reserved. In this case you can throw an DOIIdentifierExcpetion and set the error code to DOIIdentifierException.RESERVE_FIRST.

Specified by:

registerDOI in interface DOIConnector

Throws:

DOIIdentifierException

updateMetadata

public void updateMetadata(Context context,
                  DSpaceObject dso,
                  String doi)
                    throws DOIIdentifierException

Description copied from interface: DOIConnector

Sends a request to the DOI registry to update metadata for a DOI. The DOIConnector should check weather the DOI is reserved or registered for the specified DSpace Object before it sends the metadata update.

Specified by:

updateMetadata in interface DOIConnector

Throws:

DOIIdentifierException
