An
EIDR (Entertainment Identifier Registry)
identifier representing at the most general/abstract level, a work of film or television.
For example, the motion picture known as "Ghostbusters" has a titleEIDR of "10.5240/7EC7-228A-510A-053E-CBB8-J". This title (or work) may have several variants, which EIDR calls "edits". See
editEIDR.
Since schema.org types like
Movie and
TVEpisode can be used for both works and their multiple expressions, it is possible to use
titleEIDR alone (for a general description), or alongside
editEIDR for a more edit-specific description.
