In OpenAIRE/oai_datacite export, when user enters DOI in Related Publication URL field, without choosing the identifier type, include related identifier

Overview of the Feature Request

When the user enters a DOI URL in the Related Publication URL field but doesn't choose an option from the Related Publication Identifier Type dropdown, the OpenAIRE/oai_datacite export should include a related identifier with relatedIdentifierType="DOI", as the DataCite/Datacite export already does. Currently, the OpenAIRE/oai_datacite export does not include the related identifier in this case.

This issue is part of a larger effort to align both metadata exports, described in https://github.com/IQSS/dataverse/issues/11916 and https://github.com/IQSS/dataverse/issues/12281.

What kind of user is the feature intended for?

API User, Superuser, and Sysadmin

What inspired the request?

This is part of a larger effort to align the OpenAIRE/oai_datacite and DataCite/Datacite metadata exports. There is more context at https://github.com/IQSS/dataverse/issues/11916 and https://github.com/IQSS/dataverse/issues/12281.

What existing behavior do you want changed?

Currently, the DataCite/Datacite export detects when the user has entered a DOI URL in the Related Publication URL field (such as https://doi.org/10.12345/FK2/123456) without choosing an identifier type, and includes the related identifier with relatedIdentifierType="DOI". The OpenAIRE/oai_datacite export does not include the related identifier in this case.

The OpenAIRE/oai_datacite export should be changed to include the related identifier with relatedIdentifierType="DOI" when the user enters a DOI URL but doesn't choose an identifier type, matching the behavior of the DataCite/Datacite export.

Start by locating the OpenAIRE/oai_datacite and DataCite/Datacite export entry points and compare how each handles the Related Publication URL and identifier type. Use the existing DataCite behavior as the reference, then verify that a DOI URL without a selected identifier type produces a related identifier with relatedIdentifierType="DOI" in the OpenAIRE/oai_datacite output.
