Remarks

The plist and target attributes identify the participants in a relationship, while the rel attribute describes the nature of their relationship. A mutual relationship can be described using only the plist attribute – the target attribute is not necessary. In a non-mutual relationship, plist identifies the entities pointed "from", while target specifies the entities pointed "to". If the target attribute is present, but the plist is not, the relationship is presumed to exist between the parent of the current relation element and the entities identified by target.

Constraints

Within work, expression, source, or item, the value of the rel attribute must match one of the following: hasAbridgement, isAbridgementOf, hasAdaptation, isAdaptationOf, hasAlternate, isAlternateOf, hasArrangement, isArrangementOf, hasComplement, isComplementOf, hasEmbodiment, isEmbodimentOf, hasExemplar, isExemplarOf, hasImitation, isImitationOf, hasPart, isPartOf, hasRealization, isRealizationOf, hasReconfiguration, isReconfigurationOf, hasReproduction, isReproductionOf, hasRevision, isRevisionOf, hasSuccessor, isSuccessorOf, hasSummarization, isSummarizationOf, hasSupplement, isSupplementOf, hasTransformation, isTransformationOf, hasTranslation, isTranslationOf
Within work, expression, source or item, the target attribute must be present.
