KOS Relation Vocabulary

Updated 2015-10-02

Relationships between entities of different types

  1. Work (W)-to-Expression (E): (E) realizes (W)

  2. Expression (E)-to-Manifestation (M): (M) embodies (E)

Relationships between entities of the same type

  1. Work (W)-to-Work (W): based on (W), is part of (W)

  2. Expression (E)-to-Expression (E): based on (E), is part of (E), other relation (E)

These are the sub-types of dct:relation and can be used as object property in describing relationships as needed.
