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.

<mediaplayer image='http://filmstandards.org/media/hobuse_aasta_frame.png'>http://filmstandards.org/media/hobuse_aasta_clip1_ori.flv</mediaplayer> Exceprted from: Hobuse Aasta (1991) by Andres Sööt. Version with English commentary from Eesti Filmiarhiiv, Tallinn. Used with permission.

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.

We now combine our HasAsSubject references with other forms of subject description, in this case, two synopses taken from published sources, and insert them into a filmographic record for Hobuse Aasta. The transformed view example groups all subject-related statements under a Subject info section (click on the symbol to open). Here is the raw XML code for this example.
