This document defines the Cinema Preservation Package (CPP) to facilitate the digital preservation of cinematographic works. It defines methods to describe the relationship of components of the cinematographic work and delivers a syntax to describe the package content. The document itself defines the structure of the package and specifies the constraints that are necessary to enable compliance and interoperability.
Versions of the content using different encoding formats can be preserved in a layered structure where the lowest level is describing the physical file. The files can carry data representing moving images, sound, metadata or ancillary information like quality control (QC) protocols or film posters.
The Cinema Preservation Package also contains hash values on different levels to ensure data integrity and version control. The syntax for this description and the methods for the hash value generation are defined in this document. Various types of content coding are described as reference for concrete implementations.
The Cinema Preservation Package is well suited to serve as a Submission Information Package (SIP) in an OAIS compliant preservation system or as a self-contained exchange format between media archives. The CPP does not necessarily contain a complete cinematographic work, it can also be used for exchange of parts of a work.
