This European Standard specifies a set of metadata for the description of cinematographic works, as well as a terminology for use by parties wishing to exchange such descriptive metadata. It also defines some basic entities and relationships useful for defining data models as well as for structuring hierarchically ordered and serialised representations of metadata about cinematographic works including their variants, manifestations, and items. Specific vocabularies for values of elements and attributes are mandated only in selected cases, and only if these vocabularies are actively maintained by a standardisation body.
