This document defines how the XMP data model can be serialized to JSON-LD.

Abstract

Overview

ISO 16684-3:2021 - Graphic technology - Extensible Metadata Platform (XMP) specification - Part 3: JSON‑LD serialization of XMP - defines how the XMP data model is serialized to JSON‑LD. The standard provides rules and examples for converting XMP (traditionally serialized as RDF/XML) into a JSON‑based Linked Data form so XMP metadata can be used in web, semantic‑web and JSON‑centric workflows.

Key topics and requirements

Mandatory @context: All JSON‑LD serializations of XMP must include an @context mapping namespace prefixes to IRIs (namespace prefix serialization).
Property naming: XMP property names are expressed as compact IRIs (prefix:suffix) using terms defined in the @context.
Resource identity: The XMP rdf:about (AboutURI) maps to JSON‑LD @id. If no AboutURI exists, an empty @id must be present.
Type handling: Node and value typing uses JSON‑LD @type (or, where appropriate, rdf:type) to represent rdf:type and typed nodes from RDF/XML.
Value forms: The standard formalizes serialization for the three XMP value forms - simple, structure, and array - including array kinds: unordered, ordered, and alternative. JSON‑LD defaults arrays to unordered.
Literal and URI values: Simple literal values serialize as native JSON values; URI values serialize as objects with an @id key.
Qualifiers and nested structures: Rules cover qualifiers, structure fields, nested arrays and complex modeling consistent with ISO 16684‑1.
Normative references: Relies on JSON‑LD 1.1 (W3C) and BCP‑47 language tags for internationalized strings; Unicode (ISO/IEC 10646) for text.

Practical applications

Enable interoperability between image/asset metadata systems and web/JSON ecosystems.
Publish XMP metadata as Linked Data for search engines, knowledge graphs and semantic web consumption.
Facilitate metadata exchange in DAM (Digital Asset Management), publishing, archives, libraries, and media workflows where JSON is preferred.
Support modern web APIs that ingest or expose asset metadata without XML/RDF processing.

Who should use this standard

Software developers and architects implementing XMP exporters/importers
Digital asset managers, photographers, publishers, and imaging software vendors
Metadata architects, archivists and library technologists integrating XMP with web/Linked Data
Organizations migrating legacy RDF/XML XMP to JSON/JSON‑LD ecosystems

Related standards

ISO 16684‑1 (XMP data model and RDF/XML serialization)
JSON‑LD 1.1 (W3C Recommendation)
BCP‑47 (language tags)
ISO/IEC 10646 (Unicode character set)

This part of ISO 16684 ensures consistent, standards‑based conversion of XMP metadata into JSON‑LD for reliable, interoperable use across web and application environments.
