Overview
ISO/IEC 19583-26:2026 is an international standard developed by ISO and IEC, which specifies the representation of the ISO/IEC 11179-3:2013 metadata registry content using W3C XML Schema (XSD). The primary goal of this standard is to provide a common XML Schema for the exchange of compliant metadata between ISO/IEC 11179-3:2013-compatible registries. By mapping the conceptual model of ISO/IEC 11179-3:2013 into a structured, acyclic, and directed graph in XML, this standard ensures interoperable communication, robust message validation, and supports consistent content exchange across diverse information technology systems.
Key Topics
- XML Schema Definition: Describes the structure and vocabulary for ISO/IEC 11179-3:2013 in XML Schema, enabling the creation and validation of metadata exchange messages.
- Class and Attribute Mapping: Implements a vocabulary that mirrors classes, attributes, and associations from the ISO/IEC 11179-3:2013 conceptual model.
- Interoperability: Supports both strictly conforming and conforming implementations, balancing interoperability needs with extendibility.
- Schema Components:
- Common Facilities Schema: Base types and reusable definitions.
- Four Corners Schema: Assembles primary metadata registry content types.
- Message Schema: Defines document structures for message exchanges between registries.
- Conventions and Principles: Establishes mapping rules regarding namespace usage, class representation, and identifier references to ensure unambiguous data representation.
- Modelling Principles: Addresses directionality, relationship representation, and strategies for handling recursive and cyclic structures in XML.
- Use Cases: Caters to a range of registry interactions, from large-scale replication to targeted content exchanges, including integration with configurable information systems.
Applications
ISO/IEC 19583-26:2026 delivers practical solutions for organizations that manage or exchange metadata using the ISO/IEC 11179-3 framework. Its main applications include:
- Metadata Registry Interoperability: Enables diverse registry software to exchange metadata in a standardized format using XML, regardless of platform or vendor differences.
- Data Integration: Facilitates the integration of metadata registries within and across organizations by providing a validated, machine-readable schema.
- Validation of Metadata Content: Supports automated validation of exchanged messages, ensuring compliance with ISO/IEC 11179-3:2013 concepts and reducing errors in metadata sharing.
- XML Database Implementation: Offers a framework for building native XML database systems that store and maintain ISO/IEC 11179-compliant content.
- Support for Configurable Information Systems: Allows customizable applications such as survey systems and data collection tools to exchange partial or complete metadata records with central registries.
