(Main)A framework for digital preservation of cinematographic works - The Cinema Preservation Package
A framework for digital preservation of cinematographic works - The Cinema Preservation Package
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.
Ein Rahmenwerk für die digitale Erhaltung von kinematografischen Werken - Das Cinema Preservation Package
Dieses Dokument legt das Cinema Preservation Package (CPP) fest, um die digitale Erhaltung von kinematografischen Werken zu erleichtern. Es definiert Methoden zur Beschreibung der Beziehung zwischen den Komponenten des kinematografischen Werks und liefert eine Syntax zur Beschreibung des Paketinhalts. Das Dokument selbst definiert die Struktur des Pakets und legt die Einschränkungen fest, 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 Qualitätskontroll-protokolle (QC) oder Filmplakate darstellen.
Das Cinema Preservation Package enthält auch Hash-Werte auf verschiedenen Ebenen, um Datenintegrität und Versionskontrolle zu gewährleisten. Die Syntax für diese Beschreibung und die Methoden für die Hashwert-Erzeugung sind in diesem Dokument definiert. Verschiedene Arten der Inhaltskodierung werden als Referenz für konkrete Implementierungen beschrieben.
Das Cinema Preservation Package ist gut geeignet, um als Submission Information Package (SIP) in einem OAIS-konformen Archivierungssystem oder als eigenständiges Austauschformat zwischen Medienarchiven zu dienen. Das 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 définit ce qu'est un paquetage de conservation cinéma (également appelé CPP) dont l'objectif est de faciliter la conservation numérique des oeuvres cinématographiques. Il définit également des méthodes pour décrire les relations entre les composants de l'oeuvre cinématographique et fournit une syntaxe permettant de décrire le contenu du paquetage. Le document lui-même définit la structure du paquetage et précise 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 définies dans le présent document. Différents types de codage de contenu sont décrits à titre de référence pour aider concrètement à la mise en oeuvre.
Le CPP est parfaitement adapté pour servir de paquet d'information à verser (SIP) dans un système de conservation conforme à l'OAIS ou comme format d'échange autonome entre des archives de média. Le CPP ne contient pas nécessairement une oeuvre cinématographique complète, il peut également être utilisé pour échanger des parties d'une oeuvre.
Krovne določbe za digitalno varstvo kinematografskih del - Paket za varstvo filmov
Ta dokument vsebuje opredelitev paketa za varstvo filmov (CPP), njegov namen pa je olajšati digitalno varstvo kinematografskih del. Določa metode za opisovanje razmerij med komponentami kinematografskega dela in sintakso za opis vsebine paketa. Sam dokument opredeljuje strukturo paketa in določa omejitve, potrebne za zagotavljanje skladnosti in interoperabilnosti.
Različice vsebin, kodirane v različnih formatih, je mogoče arhivirati večslojno, pri čemer najnižji sloj vsebuje opis fizične datoteke. Datoteke lahko vsebujejo podatke, ki predstavljajo gibljive slike, zvok, metapodatke ali dodatne informacije, na primer protokole za nadzor kakovosti (QC) ali filmske plakate.
Paket za varstvo filmov vsebuje tudi zgoščene vrednosti na različnih ravneh, da se zagotovita celovitost podatkov in nadzor različic. Ta dokument določa sintakso za opisovanje in metode za ustvarjanje zgoščenih vrednosti. Opisane so različne vrste kodiranja vsebine, ki se uporabljajo kot referenca za izvedbo v praksi.
Paket za varstvo filmov se lahko uporablja kot sprejemni informacijski paket (SIP) v sistemu varstva, skladnem s standardom OAIS, ali kot samostojni format za izmenjavo podatkov med medijskimi arhivi. Paket za varstvo filmov ne vsebuje vedno celotnega kinematografskega dela, saj ga je mogoče uporabiti tudi za izmenjavo posameznih delov kinematografskega dela.

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.

1 Scope
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.
