Element name Relation
DCMI definition The reference to a related resource.
Usage Optional
Usage instruction Recommended best practice is to reference the resource by means of a string or number conforming to a formal identification system. The DC element ‘relation’ can be used to indicate different kinds of relations between several metadata records. If relations between metadata records are made visible by using metadata the following holds for the distinction between versions (author version and publisher version, preprint, postprint, etc.):

  • A metadata record is self-contained
  • Different manifestations of one and the same resource (an instance of scientific output that can be described with exactly the same bibliographic metadata, except for the DC element ‘format’) are linked to one single metadata record using dc:relation.
    Changes in the metadata other than the DC element ‘format’ leads to creating a new metadata record of this new instance of scientific output, which meets all requirements formulated in this document and has a value in the DC element ‘relation’.
Do not confuse with dc:identifier and dc:source.
<dc:relation> </dc:relation>
<!--  The value of dc:relation is the identifer of the other document. -->

<!-- Linking two documents:
The submittedVersion and the acceptedVersion of an article are related to each other.
The submittedVersion has identifier ""
The acceptedVersion has identifier ""
Both are related by the dc:relation element
