A framework for digital preservation of cinematographic works - The Cinema Preservation Package

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 standard 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.

Ein Rahmenwerk für die digitale Erhaltung von kinematografischen Werken - Das Cinema Erhaltungspaket

Dieses Dokument legt das Cinema Preservation Package (CPP) fest, um die digitale Erhaltung von kinematografischen Werken zu erleichtern. Es legt Methoden zur Beschreibung der Beziehung zwischen den Komponenten eines kinematografischen Werks fest und liefert eine Syntax zur Beschreibung des Paketinhalts. Das Dokument selbst legt die Struktur des Pakets fest sowie die Einschränkungen, die notwendig sind, um Konformität und Interoperabilität zu ermöglichen.
Versionen des Inhalts, die unterschiedliche Kodierungsformate verwenden, können in einer mehrschichtigen Struktur aufbewahrt werden, wobei die unterste Ebene die physische Datei beschreibt. Die Dateien können Daten enthalten, die bewegte Bilder, Ton, Metadaten oder Zusatzinformationen wie Qualitätskontrollberichte (QC) oder Filmplakate darstellen.
Das Cinema Preservation Package enthält auch Hash-Werte auf verschiedenen Ebenen, um Datenintegrität und Versionskontrolle sicherzustellen. Die Syntax für diese Beschreibung und die Methoden für die Hashwert-Erzeugung sind in diesem Dokument festgelegt. Verschiedene Arten der Pakete werden als Referenz für praktische Implementierungen beschrieben.
Das Cinema Preservation Package dient als Submission Information Package (SIP) in einem OAIS-konformen Archivierungssystem und es darf als eigenständiges Austauschformat zwischen Medienarchiven (als Distribution Information Package DIP) verwendet werden. Basierend auf den Anforderungen eines Archivs kann es auch als vollständiges Archivinformationspaket (AIP) verwendet werden, wenn die in dieser Norm für eine solche Verwendung festgelegten Einschränkungen beachtet werden.
Ein CPP enthält nicht notwendigerweise ein komplettes kinematografisches Werk, es kann auch für den Austausch von Teilen eines Werks verwendet werden.

Un cadre pour la conservation numérique des œuvres cinématographiques - Le paquetage de conservation cinéma

Le présent document spécifie ce qu'est un paquetage de conservation cinéma (également appelé CPP) dont l'objectif est de faciliter la conservation numérique des œuvres cinématographiques. Il spécifie également des méthodes pour décrire les relations entre les composants d'une œuvre cinématographique et fournit une syntaxe permettant de décrire le contenu du paquetage. Le document lui-même spécifie la structure du paquetage et les contraintes nécessaires pour assurer la conformité et l'interopérabilité.
Des versions du contenu faisant appel à différents formats de codage peuvent être conservées dans une structure hiérarchisée dont le niveau le plus bas décrit le fichier physique. Les fichiers peuvent contenir des données représentant des images animées, du son, des métadonnées ou des informations complémentaires telles que des rapports de contrôle qualité (QC) ou des affiches de film.
Le CPP contient également des valeurs de hachage à différents niveaux afin de garantir l'intégrité des données et le contrôle des versions. La syntaxe de cette description et les méthodes utilisées pour générer les valeurs de hachage sont spécifiées dans le présent document. Différents types de paquetages sont décrits à titre de référence pour aider à la mise en œuvre pratique.
Le CPP est conçu pour servir de paquet d'information à verser (SIP) dans un système de conservation conforme à l'OAIS et peut être utilisé comme format d'échange autonome entre des archives de média (sous la forme d'un paquetage d'informations de distribution (DIP)). Selon les exigences d'une archive, il peut également être utilisé comme paquetage d'informations d'archivage (AIP) complet si les contraintes énoncées dans la présente norme pour une telle utilisation sont respectées.
Un CPP ne contient pas nécessairement une œuvre cinématographique complète, il peut également être utilisé pour échanger des parties d'une œuvre.

This document (prEN 17650:2021) has been prepared by Technical Committee CEN/TC 457 “Digital

preservation of cinematographic works”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.

Introduction

This document is part of a series of standards and technical recommendations for the digital preservation

of cinematographic work. It gives European film archives and producers a guideline how to store and

manage film content in the digital age. The document references many existing formats and elements and

serves as a super-format which includes other existing sub-formats like DCPs or IMPs for movies, XML-

files for packaging-lists or subtitles, AV files and metadata files. In addition, methods will be integrated to

ensure data integrity and quality by calculating hash and fingerprinting-values.

This document reuses describing tools and archiving formats from the cinema archiving community as

much as possible.
