Add explicit support for RAiD to relatedIdentifier

[mpfl]

What is the problem that your suggestion solves?

At the moment, a RAiD can only be used in relatedIdentifier as a generic URL.

Although DataCite DOIs are used to underpin the stability and persistence of RAiDs, the DOI that is minted as a part of the RAiD minting process should never be used in place of the actual RAiD.

Furthermore, with the release of ISO 26324:2025, a DOI should not be used in place of a RAiD:

"A DOI name shall not be used as a replacement for other ISO identifier schemes such as ISAN (ISO 15706-1 and ISO 15706-2), ISBN (ISO 2108), ISRC (ISO 3901), ISSN (ISO 3297), ISNI (ISO 27729), ISWC (ISO 15707), ISCI (ISO 27730), ISMN (ISO 10957), RAiD (ISO 23527) and other commonly recognized identifiers."

What solution might meet your needs?

Add RAiD to the relatedIdentifierType list.

Thanks for submitting this suggestion, @mpfl!

Out of curiosity, I took a look at whether RAiDs are already being used in RelatedIdentifier. I was surprised to see they are mostly(?) being provided with relatedIdentifierType="DOI": https://api.datacite.org/dois?query=relatedIdentifiers.relatedIdentifier:*raid*

For example:

{
"relationType": "IsPartOf",
"relatedIdentifier": "https://raid.org/10.71821/418be95a",
"resourceTypeGeneral": "Project",
"relatedIdentifierType": "DOI"
}

We've started to formally define this and welcome feedback here: Request for comment: New relatedIdentifierType "RAiD"

Thanks, @borsna! I've added the "Integrated" label and will post an update here, as well as on the other posts related to features added in 4.7.

This has been integrated with the recent release of DataCite Metadata Schema 4.7, which adds a relatedIdentifierType "RAiD". Find more information about the release here: https://schema.datacite.org/meta/kernel-4.7/
