View source for Events in the lifecycle of an audiovisual creation

Like most other intellectual or artistic creations, audiovisual works can undergo '''many stages''' of realisation, usage, modification and re-use. Introducing the concept of '''event''' allows us to capture details about these stages as machine-processable metadata.

Most current cataloguing systems for cinematographic works do not have data elements for events. Instead, '''statements about events''' are typically written into '''note fields'''.

The text on the left is from such a note field, created by the designers of the IMDb for remarks about alternate '''versions'''.

EN 15907 defines six '''types of events''' for describing occurrences in the lifecycle of a cinematographic work.

An event is characterised by '''time''' (however imprecise or unknown) and a '''location''' (however imprecise or unknown). It can be associated with agents (i.e. people, corporations), artifacts, or whatever may be of interest in its context.

Note the absence of a destruction event, following FIAF's motto, ''Don't throw away film''.

A '''production event''' typically encompasses the shooting of a film and all subsequent stages of production and post-production. 

Any activity that creates a '''new variant or manifestation''' of a cinematographic work can also be described as a production event.

Publication events encompass all kinds of '''public exhibition''' including premieres, festival screenings, TV broadcasts, etc.

Publication on a '''carrier''' such as DVD, or '''on-line''' releases, also count as publication events.

'''Awards''' are modelled as events because their bestowal occurs at a specific time. Awards are often associated with other events such as film festivals.

An award can be specific to a '''person''' and/or to a particular achievement. It can also be specific to a particular '''version''' or '''manifestation'''.

Decision events cover all acts of '''censorship''' and all decisions made by agencies under a voluntary '''rating''' scheme.

Decisions are usually specific to a particular '''manifestation''' of a cinematographic work. They can also give rise to a new variant in cases where the decisison results in significant changes in the content of the public release.

Some countries have (or had) registration schemes for '''intellectual property rights''', applicable to moving image works.

EN 15907 defines this event type for cases in which such registration is known.

This class of events comprises activities that are ususally based on a single copy. Preservation events can produce a new '''copy''', or a new '''manifestation''' if the resulting copy is used as a master for duplication,

In cases where different fragments are combined in order to '''reconstruct''' a cinematographic work, this should be regarded as a production event resulting in a new '''variant'''.
