View source for EN 15907 Variant

==Definition from the standard==

{|style="background-color:#C8C8C8"
|
The Variant entity is used as a description level for statements about content-related characteristics that may vary without changing the overall content of a cinematographic work. Such variants can be produced by minor additions, deletions or substitutions to the intellectual or artistic content as long as these do not significantly affect the content as a whole. As a general rule, any change that would result in a different content description (if such exists) should be treated as a separate cinematographic work rather than a variant. Statements about
the extent of a variant are not defined at this level of description.

Each instance of Variant is related to a [[EN 15907 Cinematographic Work|Cinematographic Work]] and may have one-to-many relationships with instances of Manifestation, and many-to-many relationships with instances of Agent and Event. 

If no variant of a cinematographic work is known, then the instance of this entity may be omitted or represented by an empty node connecting an instance of [[EN 15907 Cinematographic Work|Cinematographic Work]] with one or more instances of Manifestation.
