This property is used to declare that two resources which may or may not conform to the FRBR (Functional Requirements for Bibliographic Resources) entity model share the same Manifestation. An example of its use would be to relate a resource described with a vocabulary such as bibo (which does not acknowledge the FRBR model) to other resources that describe endeavours which include the same implied Manifestation (which could be other bibo resources or FRBR entities or anything else).
