Related identifiers

The DataCite Metadata Schema includes a relatedIdentifier property to facilitate links to related research outputs.

The relatedIdentifier property has a mandatory attribute, relationType, which is used to describe the type of relationship. All relationTypes in the DataCite Metadata Schema are listed below (Summary of all relationTypes).

Specific use cases are highlighted below.

Citations and references

Citations and references can be provided through the relatedIdentifier property with specific relationTypes:

  • Citations use the relationTypes IsCitedBy, IsReferencedBy, and IsSupplementTo.
  • References use the relationTypes Cites, References, and IsSupplementedBy.

For more information, see the Citations and References section of the documentation, including:

Parts and versions

Whole/part relationships can be represented using related identifiers with the relationTypes HasPart and IsPartOf.

Version relationships can be represented using related identifiers with the relationTypes HasVersion and IsVersionOf. When one version supersedes another, use the pair IsNewVersionOf and IsPreviousVersionOf. For more information on versioning, see Versioning.

Information about parts and versions is exposed in the “relationships” section of the DataCite REST API. This information is also available via the DataCite GraphQL API.
