EN 15907 Manifestation

Definition from the standard

A manifestation is the physical embodiment of a cinematographic work or one of its variants. Since cinematographic works are also distributed online, i.e. without a fixed physical carrier, the definition in this standard also encompasses computer files. A manifestation is not exclusively bound to a single cinematographic work or variant, since publishers may choose to combine more than one variant of a cinematographic work or more than one cinematographic work on a single distribution medium. The distribution medium itself can be composed of several units of the same kind. Instances of Manifestation may have one-to-many relationships with instances of Item and Event, and many-to-many relationships with instances of Cinematographic Work or Variant.
