This document specifies the Cinema Preservation Package (CPP) to facilitate the digital preservation of cinematographic works. It specifies methods to describe the relationship of components of a cinematographic work and delivers a syntax to describe the package content. The document itself specifies the structure of the package and 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) reports 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 specified in this document. Various types of packages are described as reference for practical implementations. The Cinema Preservation Package is designed to serve as a Submission Information Package (SIP) in an OAIS compliant preservation system, and it may be used as a self-contained exchange format between media archives (as Distribution Information Package DIP). Based on the requirements of an archive, it can also be used as complete Archival Information Package (AIP) if the constraints set out in this document for such use are adhered to. A CPP does not necessarily contain a complete cinematographic work, it can also be used for the exchange of parts of a work.
