Related Identifier (MA, 0-n)¶

datacite:relatedIdentifier

Identifiers of related resources other than the resource being registered. OpenAIRE especially encourages relating datasets with publications and software, but appreciatively welcomes other kinds of relations too.

Property relatedIdentifier (MA, 0-n)¶

Allowed values, other constraints:

A related identifier must be globally unique and should be durable. Preferrably it is registered with an established identification system, or is a permalink or stable URL.
The format is free text - a unique string that unambiguously identifies a resource within its given context and follows the respective specifications.

Attribute relatedIdentifierType (M, 1)¶

The type of the related identifier.

Controlled list values:

IsContinuedBy/Continues - (A is continued by the work B) / (A is a continuation of the work B)
Describes/IsDescribedBy - (A describes B) / (A is described by B)
HasMetadata/IsMetadataFor - (resource A has additional metadata B) / (additional metadata A for a resource B)
HasVersion/IsVersionOf - (A has a version (B)) / (A is a version of B)
IsNewVersionOf/IsPreviousVersionOf - (A is a new edition of B, where the new edition has been modified or updated) / (A is a previous edition of B)
IsPartOf/HasPart - (A is a portion of B, may be used for elements of a series) / (A includes the part B)
IsReferencedBy/References - (A is used as a source of information by B) / (B is used as a source of information for A)
IsDocumentedBy/Documents - (B is documentation about/explaining A) / (A is documentation about/explaining B)
isCompiledBy/Compiles - (B is used to compile or create A) / (B is the result of a compile or creation event using A)
IsVariantFormOf/IsOriginalFormOf - (A is a variant or different form of B, e.g. calculated or calibrated form or different packaging) / (A is the original form of B)
IsIdenticalTo - (A is identical to B, for use when there is a need to register two separate instances of the same resource)
IsReviewedBy/Reviews - (A is reviewed by B) / (A is a review of B)
IsDerivedFrom/IsSourceOf - (B is a source upon which A is based) / (A is a source upon which B is based)
IsRequiredBy/Requires - (A is required by B) / (A requires B)
IsObsoletedBy/Obsoletes - (A is replaced by B) / (A requires B)

Cites and IsCitedBy is dedicated to publications/datasets directly citing other publications/datasets in their references, whereas References and IsReferencedBy describes datasets/publications being used as information sources without direct citations.

Attribute resourceTypeGeneral (O, 0-1)¶

The main category the related resource belongs to.

Controlled list values:

literature

software
other

Attribute relatedMetadataScheme (O, 0-1)¶

The name of the metadata scheme.

Allowed values, other constraints:

The URI of the relatedMetadataScheme.

Allowed values, other constraints:

Use only with this relation pair: (HasMetadata/IsMetadataFor).

Attribute schemeType (O, 0-1)¶

Context¶

Do Not Confuse With

Identifier (M, 1) (Use identifier for the primary identifier of the same resource instance.)
Alternative Identifier (R, 0-n) (Use alternateIdentifier for secondary or local identifiers of the same resource, and also for landing pages and download pages.)

DataCite v4.3 Differentiation

relatedIdentifier_ is mandatory when applicable in OpenAIRE instead of recommended in DataCite.
relatedIdentifierType_ allows more types in OpenAIRE than in DataCite.
resourceTypeGeneral_ suggests other types in OpenAIRE than in DataCite.
