To reserve or register a DOI, DataCite requires that metadata be supplied which describe the object that the DOI addresses. The file [dspace]/config/crosswalks/DIM2DataCite.xsl controls the conversion of metadata from the DSpace internal format into the DataCite format. You have to add your DOI prefix, namespace separator and the name of your institution to this file, on lines 16 and 18 respectively in the following excerpt:

If you want to know more about the DataCite Schema, have a look at the documentation. If you change this file in a way that is not compatible with the DataCite schema, you won't be able to reserve and register DOIs anymore. Do not change anything if you're not sure what you're doing.

You can test the functionality of your DataCite crosswalk by running the following command in a shell:

Code Block
languagebash
[dspace]/bin/dspace dsrun org.dspace.content.crosswalk.XSLTDisseminationCrosswalk DataCite [ITEM-HANDLE] [PATH-TO-OUTPUT-FILE.XML]


Identifier Service

The Identifier Service manages the generation, reservation and registration of identifiers within DSpace. You can configure it using the config file located in [dspace]/config/spring/api/identifier-service.xml. In the file you should already find the code to configure DSpace to register DOIs. Just read the comments and remove the comment signs around the two appropriate beans.
