CEN/TC 457 - Preservation of digital cinema movies

This Technical Report defines guidelines and gives implementation advice how to organize and structure the Cinema Preservation Packageas (CPP) as defined in the European standard EN 17650.  It facilitates the digital preservation of cinematographic works. It explains the methods to describe the relationship of components of the cinematographic work and demonstrates the syntax to describe the package content. While EN 17650 defines the structure of the package and specifies the constraints that are necessary to enable compliance and interoperability, this document explains its usage.
This documetn demonstrates examples for the structure of the Cinema Preservation Package and the usage of metadata schemes for structural, descriptive, provenance and technical metadata. Examples for METS, EBUCore and playlist files are given in the technical report.

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.
