ISO/IEC 23001-1:2006 PDF

Overview

ISO/IEC 23001-1:2006 - Binary MPEG format for XML (BiM) - specifies a standardized set of technologies for encoding, compressing and transporting XML documents in an efficient binary form. The standard defines system-level behavior for ISO/IEC 23001-1 compliant terminals (decoders), rules for preparing XML for optimized transport and storage, fragmentation and reassembly mechanisms, and methods to share or compile schema knowledge so compressed XML can be decoded even when the receiver lacks the original schema.

Key topics and technical requirements

• System architecture and decoder behavior: normative definitions of an ISO/IEC 23001-1 terminal, initialization sequence, and decoder processing expectations.
• Binary format (BiM): binary syntax and semantics for structural elements, including the concept of a Binary Access Unit and units for fragment, schema and command handling.
• Fragmentation and transport: mechanisms for partitioning XML documents into fragment/update units to support flexible transmission and partial processing.
• Schema-based compression: leveraging shared schema knowledge between encoder and decoder to achieve high compression efficiency; also provisions for transmitting schema information when receivers lack a priori schema.
• Fragment update payloads and decoding: binary payload syntax and semantics for element content and complex type decoding (finite-state automaton approach).
• Advanced optimized decoders: optional decoder mechanisms for efficient decoding of simple types (e.g., quantizers, zlib-based approaches listed in the standard) to improve performance and compression.
• Normative references: aligns with XML, XML Schema, XPath, RFCs (URI syntax), ZLIB format and character-set standards.

Applications and who uses it

ISO/IEC 23001-1:2006 is targeted at implementers and architects who need compact, transport-friendly representations of XML in multimedia and metadata systems:

• Multimedia systems and streaming services using XML metadata (e.g., MPEG-7) to reduce bandwidth and storage.
• Device and terminal manufacturers building decoders that receive compressed XML over networks or broadcast.
• Developers of metadata frameworks (MPEG-7, MPEG-21) needing standardized binary XML encodings.
• Broadcast, mobile and low-bandwidth applications where efficient encoding, fragmentation and partial updates of XML are required.
• Standards implementers and integrators requiring deterministic decoder behavior and interoperable binary XML formats.

Related standards

• ISO/IEC 15938-1 (MPEG-7 Systems) - for MPEG-7 metadata usage.
• ISO/IEC 21000-16 (MPEG-21 Binary Format) - for MPEG-21 usage.
• W3C XML and XML Schema (normative references), RFC 2396 (URI), RFC 1950 (ZLIB).

Note: Implementers should review Annex C of the standard for patent statements and licensing considerations when deploying BiM-based solutions.
