Error loading DataCite schema v.4 crosswalk stylesheet
Kiriaki Roditi
Hello to All,
Having trouble updating the Datacite crosswalk to use Schema version 4 on a DSpace v.6.3 installation.
I have updated DIM2DataCite.xsl , dspace.fg, local.cfg and DataCiteConnector.java to use http://datacite.org/schema/kernel-4
The error in the console when I try to update a DOI is
ERROR: 'Syntax error in ''.'
FATAL ERROR: 'line 242: Required attribute 'select' is missing.'
This is the excerpt from the logs
ERROR org.dspace.content.crosswalk.XSLTCrosswalk @ Failed to initialize XSLTCrosswalk(DataCite): javax.xml.transform.TransformerConfigurationException: line 242: Required attribute 'select' is missing.
ERROR org.dspace.identifier.doi.DataCiteConnector @ Caught an CrosswalkException while reserving a DOI for DSO with type 2 and ID 6ba15ba8-0fae-43e7-b7cc-73de23d9098d. Won't reserve the doi.

What am I missing?
Is there another configuration property that I need to change? Does it have to do with the metadata stored in dc.type field?

Probably an 'apply-templates' element is missing its required 'select'.

The only part of the file I have edited, compared to the one referenced from Github, is in the beginning, the properties for
<xsl:param name="prefix"> and <xsl:param name="publisher">
I have tested with some alternative versions of DIM2DataCite.xsl published in an August commit and the error is always in the same line of the resourceType element.
https://github.com/DSpace/DSpace/blob/e8a2e73fcc9b7944408daf6a6f683b69939949cd/dspace/config/crosswalks/DIM2DataCite.xsl#L242
Our institution 's metadata is in Greek (language code: el), dc.type field is required and filled for all repository items and it works effortlessly for Datacite Schema v.3
Is there some other configuration file (i.e. pom.xml, spring...) that I should declare the new Datacite Schema version?
Many thanks,
Kiriaki

- adding the type metadata to each items with value Other;
- replacing the line 242 of DIM2DataCite.xsl with a costant string (Other) or introducing a parameter (<xsl:param name="defaultType">Other</xsl:param>) and change the line 242 with <xsl:value-of select="$defaultType">

Hello all,
Danilo thank you very much for the help!
John thank you for the feedback!
I have been testing this all morning but unfortunately it did not work for me.
Changed the resourceType element as described and modified an item’s metadata field dc.type to a term in English. I created the Datacite.xml file through the console ( dsrun org.dspace.content.crosswalk.XSLTDisseminationCrosswalk DataCite myhandle ) for this item and tested.
Pasting the resource type xml element, created with the new stylesheet:
<resourceType resourceTypeGeneral="Other">Bachelor Thesis</resourceType>
and the three first lines from the xml
<?xml version="1.0" encoding="UTF-8"?>
<resource xmlns=http://datacite.org/schema/kernel-4 xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance xmlns:dspace=http://www.dspace.org/xmlns/dspace/dim xsi:schemaLocation=http://datacite.org/schema/kernel-4 http://schema.datacite.org/meta/kernel-4/metadata.xsd>
<creators>
<creator>
When I run doi-organiser --update-doi myhandle a get a 422 error
This is the log excerpt from my last test.
2025-01-10 13:49:35,554 WARN org.dspace.identifier.doi.DataCiteConnector @ While reserving the DOI doi:xxxxxx, we got a http status code 422 and the message "DOI xxxxxx: This element is not expected.

But, when I used the mentioned Datacite.xml file to create a Draft DOI through Fabrica it worked.
How else can I reproduce what the API sends to Datacite? Any thoughts?
Greetings from sunny Athens,
Kiriaki
