Description levels: A worked example

From the TC 372 Workshop Compendium

Description levels do not only offer new ways for user interaction with filmographic databases, but can also ecenomise the production of metadata.

This short piece is a trailer. For the moment, we will ignore the question if a trailer can be regarded as a version or variant of the work which it advertises, or if it is something entirely different. This trailer just serves to give us an idea of the work that will be discussed in the following.

This is from the EN 15907 definition of cinematographic work. The idea here is to have a description level for all statements that remain unchanged for all variants and manifestations of the work. Note that this definition is different from the FRBR concept of work, which abstracts from any particular embodiment. Since any moving image work is created by realising it in some moving image medium, it does not fit the FRBR definition of work.

An elementary work-level description would comprise the elements from EN 15744 minus those that do not belong to the work level in EN 15907. The figure on the left gives an idea of what a minimum work-level description could look like. Here is the XML record, the transformation script, and the resulting HTML page.
