Full title and description

Information technology — JPEG Systems — Part 5: JPEG universal metadata box format (JUMBF). This International Standard specifies the JUMBF box syntax and the mechanisms to carry and identify arbitrary metadata types (XML, JSON, CBOR, Embedded File, codestream, UUID, etc.) in any box‑based JPEG file format, and defines ways to reference or request embedded metadata inside or outside an image file.

Abstract

The document defines a universal metadata container (the JUMBF box) for use across JPEG Systems file formats. It standardizes content type identifiers, payload structures for common metadata encodings (XML, JSON, CBOR), embedded file handling, codestream references and UUID payloads, plus mechanisms to reference or request metadata externally. An amendment addressing JUMBF box compression and standalone JUMBF files was published subsequently.

Scope

This part of JPEG Systems defines a generic, extensible box format (JUMBF) to carry arbitrary metadata within any box‑based JPEG file format and to support standalone JUMBF files. It specifies the box syntax, standardized content types (including XML, JSON, CBOR, Embedded File, codestream and UUID) and the referencing/requesting mechanisms to access metadata inside or outside an image container. The scope includes interoperability requirements so different JPEG formats and applications can locate, identify and process embedded metadata consistently.

Key topics and requirements

• Definition of the JUMBF box structure and box header/sizing rules.
• Standardized Content Types: XML, JSON, CBOR, Embedded File, codestream, UUID (identifiers and payload rules).
• Mechanisms for referencing embedded metadata from within or outside the image (URI/identifier and request semantics).
• Guidance for embedding metadata in any box‑based JPEG container and for standalone JUMBF files (amendment adds explicit rules for compression and standalone files).
• Interoperability constraints so tools can locate, parse and validate JUMBF payloads across JPEG Systems parts.

Typical use and users

Used by imaging software developers, digital asset management and archive systems, camera and device firmware teams, content distribution platforms, metadata tool vendors, forensic and provenance systems, and any integrator who needs a consistent, extensible way to embed or attach structured metadata to JPEG family images. Common applications include rights and provenance metadata, structured descriptive metadata (XML/JSON), auxiliary images or resources packaged with an image, and tools that exchange metadata-rich JPEG assets across workflows.

Related standards

ISO/IEC 19566 is a multipart family (JPEG Systems). Closely related parts include Part 1 (packaging/guidance), Part 2 (transport mechanisms), Part 4 (privacy & security), Part 6 (JPEG 360), Part 7 (JPEG linked media format — JLINK), Part 8 (JPEG Snack) and additional parts such as reference software and extension mechanism parts. Implementers typically consult the wider JPEG family and related image coding standards when integrating JUMBF.

FAQ

Q: What is this standard?

A: ISO/IEC 19566-5:2023 is the JPEG Systems specification that defines the JPEG Universal Metadata Box Format (JUMBF) — a standardized container for embedding and referencing arbitrary metadata in box‑based JPEG file formats.

Q: What does it cover?

A: It covers the syntax and semantics of the JUMBF box, standardized content types (XML, JSON, CBOR, Embedded File, codestream, UUID), and mechanisms to reference or request metadata inside or outside image files. An amendment (2025) adds rules for JUMBF box compression and standalone JUMBF files.

Q: Who typically uses it?

A: Software and firmware developers working with JPEG formats, DAM/archive engineers, content distribution and publishing platforms, metadata/tool vendors, and practitioners concerned with interoperability of metadata and auxiliary resources associated with JPEG images.

Q: Is it current or superseded?

A: The 2023 edition (Edition 2) is the current published International Standard; it has an associated Amendment published in 2025 addressing compression and standalone JUMBF files and is maintained within the ISO/IEC review cycle. Check national standards bodies or the ISO/IEC catalog for the latest status and any newer amendments or edition changes.

Q: Is it part of a series?

A: Yes — it is Part 5 of the ISO/IEC 19566 JPEG Systems multipart family. Other parts address packaging, transport, privacy/security, JPEG 360, JLINK and related system‑level functionality. Implementers often use multiple parts of ISO/IEC 19566 together.

Q: What are the key keywords?

A: JUMBF, metadata box, JPEG Systems, XML, JSON, CBOR, embedded file, codestream reference, UUID, interoperability, ISO/IEC 19566-5:2023.
