Overview
ISO 17369:2013 - Statistical Data and Metadata Exchange (SDMX) defines an integrated, interoperable approach for exchanging, reporting and disseminating statistical data and related metadata. At its core is an SDMX information model designed for national and supranational statistical organizations but applicable to any organization that manages structured statistical reporting. The standard covers syntax-specific implementations (SDMX‑ML and SDMX‑EDI), registry services, web‑service guidelines and supporting technical notes to enable automated, consistent data interchange.
Key Topics
- SDMX information model: a syntax‑neutral UML model describing data sets, metadata sets, concepts, and relationships used for interoperable exchange.
- Data Structure Definition (DSD): the structured collection of metadata concepts and rules that organize statistical data for collection and dissemination.
- Metadata structure and reference metadata: models for quality, methodology and provisioning metadata (metadataflow) in addition to structural metadata.
- SDMX‑ML: XML‑based format for SDMX messages, aligned with the information model for object‑oriented processing.
- SDMX‑EDI: UN/EDIFACT format support for SDMX messages to accommodate legacy and international EDI workflows.
- Registry specification: defines services for registration, querying and subscription/notification of available data and metadata (SDMX registry).
- Web services and RESTful APIs: guidance for implementing SDMX using HTTP/REST or SOAP web services and related WSDL/WADL considerations.
- Key concepts and vocabularies: code lists (including hierarchical code lists), concept schemes, dataflow and metadataflow definitions, provision agreements, structure sets and reporting taxonomies.
- Versioning and compatibility: evolution from earlier SDMX releases (notably SDMX 2.0 → 2.1) to improve XML schema alignment, presentation, and support for non‑time‑series data and partial code lists.
Applications
ISO 17369:2013 is practical for:
- Automating exchange between national statistical offices, international agencies and data providers.
- Building SDMX‑compatible registries and web services for publishing statistical releases and release calendars.
- Converting legacy statistical formats to a standardized XML or EDIFACT interchange.
- Implementing machine‑readable dataflow and metadataflow pipelines to support analytics, dashboards and OLAP systems.
- Standardizing code lists, DSDs and metadata to improve data quality, discoverability and reuse.
Who should use it
- National statistical offices and supranational organizations (Eurostat, IMF, World Bank).
- Data providers, data aggregators and national ministries.
- IT architects, data engineers and developers building statistical exchange services or SDMX‑compliant tools.
- Registry and metadata managers responsible for provisioning and subscription services.
