View source for Approaching the subject of a film work

''From the [[TC 372 Workshop Compendium]]''

== A worked example ==

'''Documentary films''' are typically searched for '''by subject'''. While content description and keyword indexing are mainstay procedures in film cataloguing, today's networked environment allows for almost anything to be related to a cinematographic work in the role of ''subject''.

This is a documentary about events in Estonia before the country gained independence from the Soviet Union in early 1991. The clip contains images from the parliamentary assembly of 26 January, 1990, in which an amendment of the constitution was attempted.

The '''content''' of this clip clearly '''focuses on people''', in this case on those that represented the leading political class in Estonia until 1990.

The people depicted in the clip cannot be regarded as active contributors to the film work, since their activity would also have taken place in the absence of a camera. In cases where a person is not an ''Agent'' in the sense or our reference model, we can still construct relationships to persons or other agent entities by using the semantics of ''Subject''.

EN 15907 defines a '''HasAsSubject relationship''' for connecting any entity type (including film and non-film objects) to a cinematographic work. In this example, we refine this to a '''showsPerson''' relationship, using a specialisation from a corresponding type vocabulary.
