What steps does it take to reproduce the issue?

1. Activate CVocConf (https://github.com/gdcc/dataverse-external-vocab-support/blob/main/examples/authorIDandAffilationUsingORCIDandROR.md)
2. Create Dataset
3. Introduce any author using ORCID author functionality
4. Publish Dataset

When does this issue occur?

• While publishing Dataset.

Which page(s) does it occurs on?

• You can see it on this page: $SERVER/api/datasets/export?exporter=Datacite&persistentId=doi:xxxx/xxxx, after Dataset publication.

What happens?

• Datacite does not recive ORCID values and Datacite Metadata export has not ORCID fields.

• The problem is that the file people.js (https://github.com/gdcc/dataverse-external-vocab-support/blob/main/scripts/people.js) fills the hidden field Author -> Identifier with the pattern https://orcid.org/xxxx-xxxx-xxxx-xxxx and then Dataverse, in ExternalIdentifier.java, does not consider that possibility and the getIdentifierAsUrl method of the DatasetAuthor class return null.

To whom does it occur (all users, curators, superusers)?

• All users

What did you expect to happen?

• Datacite recived ORCID fields and Datacite Metadata export was correct.

Which version of Dataverse are you using?

• 6.4

Help is always welcome, is this bug something you or your organization plan to fix?

• Our organization fixed the issue by changing src/main/java/edu/harvard/iq/dataverse/ExternalIdentifier.java so that Author -> Identifier with the format: https://orcid.org/xxxx-xxxx-xxxx-xxxx is accepted. We are not sure if would be better to change (https://github.com/gdcc/dataverse-external-vocab-support/blob/main/scripts/people.js) instead.

• Correct Datacite Metadata export
  

• Correct Datacite Test Registry
  

• Code Change Possible Solution
