scope:

This document specifies a generic method for mapping a D-Cinema Package (DCP) onto one or more file storage volumes. Data structures are specified which provide for the mapping of D-Cinema asset identifier values onto paths within a particular file storage scheme (e.g., filesystem paths). Where required, assets may be split across multiple storage volumes to allow efficient use of media and the mapping of assets larger than a given storage volume's capacity. The Asset Map and Volume Index structures and the associated provisions detailed herein are intended to provide a framework for simplified mapping of a DCP onto a wide variety of file storage systems.
