Full title and description

ISO/IEC 21000-9:2005 — Information technology — Multimedia framework (MPEG-21) — Part 9: File Format. This part specifies a box-structured file format for packaging MPEG-21 Digital Items: a base MPEG-21 XML document together with zero or more ancillary resources, using concepts from the ISO Base Media File Format to enable single-file transport and storage of digital items for delivery and consumption.

Abstract

ISO/IEC 21000-9:2005 (MPEG-21 File Format) defines an open framework for packaging multimedia digital items so they can be delivered and consumed across diverse networks and devices. The format is box-structured, intended to hold a primary MPEG-21 XML document and associated resources in a single package, and is built using tools from the ISO Base Media File Format (ISO/IEC 14496-12). The standard was published in 2005 and has at least one amendment (MIME type registration) issued in 2008.

General information

• Status: Published (confirmed after periodic review).
• Publication date: July 2005 (Edition 1, 2005).
• Publisher: ISO/IEC (JTC 1 / SC 29, MPEG working group).
• ICS / categories: 35.040.40 (Coding of audio, video, multimedia and hypermedia information).
• Edition / version: Edition 1 (2005); amended by ISO/IEC 21000-9:2005/Amd 1:2008 for MIME type registration.
• Number of pages: 6 (main document).

Scope

Specifies a file-format container for MPEG-21 Digital Items that can hold a primary MPEG-21 XML Digital Item Declaration and its ancillary resources (audio, video, images, metadata, etc.) in a single, box-structured package. The format leverages the ISO Base Media File Format mechanisms (e.g., boxes/atoms) to represent both untimed metadata and integrated document handling, enabling interoperability for packaging, storage, and transport of MPEG-21 content. The amendment in 2008 added MIME type registration details for the format.

Key topics and requirements

• Definition of a box-structured file container tailored to MPEG-21 Digital Items (primary XML document plus ancillary resources).
• Use of ISO Base Media File Format principles (ISO/IEC 14496-12) for structural interoperability and metadata handling.
• Guidance for embedding, referencing and organizing ancillary resources (media assets, metadata, descriptors) within the package.
• Requirements for representing untimed (static) metadata and relationships between digital-item components.
• MIME type registration and registration-related metadata (addressed via Amendment 1:2008).
• Conformance considerations to ensure players, toolchains and servers can locate and interpret the MPEG-21 Digital Item within the file container.

Typical use and users

Used by implementers of MPEG-21 toolchains, digital library custodians, media distributors, content providers and vendors who need a standardized single-file container for MPEG-21 Digital Items. Typical applications include archival packaging, content distribution, delivery to heterogeneous devices, and scenarios requiring bundled metadata and resources for automated processing by MPEG-21-aware tools. Developers of media players, authoring tools, DAM (digital asset management) systems and standards integrators are likely users.

Related standards

ISO/IEC 21000 is a multipart MPEG-21 suite; related parts include ISO/IEC 21000-1 (vision/overview), -2 (Digital Item Declaration), -3 (Digital Item Identification), -5 (Rights Expression Language), -6 (Rights Data Dictionary), -7 (Digital Item Adaptation), -8 (Reference Software), -10 (Digital Item Processing) and others in the MPEG-21 family. The File Format specification also relies on concepts from the ISO Base Media File Format (ISO/IEC 14496-12) and therefore relates technically to ISO/IEC 14496 family publications.

FAQ

Q: What is this standard?

A: ISO/IEC 21000-9:2005 is Part 9 of the MPEG-21 suite that specifies a file-format container for MPEG-21 Digital Items (a primary MPEG-21 XML document plus associated resources) to support packaging, transport and storage of multimedia digital items.

Q: What does it cover?

A: It covers the structural definition of a box-based file container suitable for MPEG-21 Digital Items, rules for embedding or referencing ancillary resources, metadata organization, and interoperability mechanisms based on the ISO Base Media File Format; an amendment in 2008 added MIME type registration details.

Q: Who typically uses it?

A: Content distributors, digital-asset managers, implementers of MPEG-21 toolchains, media-authoring and playback software developers, archives and any organization needing a standardized package for MPEG-21 Digital Items.

Q: Is it current or superseded?

A: The document was published in 2005 (Edition 1) and received an amendment in 2008 for MIME registration. According to ISO lifecycle records the 2005 edition was reviewed and confirmed (most recent review noted in ISO records), so the edition remains the current published version unless superseded by a later edition (none published to replace it as of the last ISO confirmation). Users should check the official ISO catalog or national standards body for the absolute current status before procurement or conformance work.

Q: Is it part of a series?

A: Yes — it is Part 9 of the ISO/IEC 21000 (MPEG-21) multipart standard that defines an end-to-end multimedia framework; other parts cover DID, identification, rights expression, adaptation, reference software and more.

Q: What are the key keywords?

A: MPEG-21, Digital Item, file format, packaging, ISO Base Media File Format, box-structure, DID (Digital Item Declaration), MIME type registration.
