Statistical Data and Metadata eXchange

What Statistical Data and Metadata eXchange does

Statistical Data and Metadata eXchange (SDMx) is an international standards initiative, governed under a Memorandum of Understanding signed in March 2007 by a consortium of eight sponsoring organisations: the Bank for International Settlements (BIS), European Central Bank (ECB), Eurostat, International Labour Organization (ILO), International Monetary Fund (IMF), Organisation for Economic Co-operation and Development (OECD), United Nations (UN), and World Bank Group. The initiative maintains ISO 17369, the international standard for statistical data and metadata exchange, which was first published as an ISO Technical Specification in 2005 and approved as a full International Standard on 8 January 2013. SDMx is designed for national statistics offices, national central banks, and institutional organisations to standardise and optimise data operations, and its user community spans over 80 countries.

The technical portfolio centres on the core SDMx standard, a web-based Global Registry hosting Data Structure Definitions across domains such as National Accounts, Consumer Price Index, Balance of Payments, Foreign Direct Investment, and the System of Environmental-Economic Accounting, the Validation and Transformation Language (VTL) for data validation and transformation rules, a RESTful API specification supporting SDMX-ML, SDMX-JSON, FUSION-JSON, EDI, and XLSX formats, and a Test Compatibility Kit for compliance testing. Versioning has progressed from SDMx 3.0 (which added microdata and geospatial support in 2021) to SDMx 3.1 (2024, with horizontally complex DSDs) and VTL 2.1 (August 2024). The standard was rebranded from SDMX to SDMx on 29 June 2026, with the strategic emphasis shifting from data exchange to data leadership and AI-readiness.

SDMx operates as an open, non-commercial standard. The standard, specifications, and open-source tools are provided free of charge, and there is no revenue model, pricing schedule, or customer billing structure. Funding flows through the eight sponsoring international organisations and in-kind contributions from Technical and Statistical Working Groups established in 2011. Distribution occurs via the sdmx.org website, GitHub repositories under sdmx-twg, the Global Registry, a LinkedIn community, and biennial Global Conferences and Experts Workshops, with the 10th Global Conference convening over 300 participants from 80 countries in Rome in September 2025 and the 13th Experts Workshop scheduled for Ankara in late 2026.

Core offering

SDMx develops and maintains ISO 17369, the international standard for statistical data and metadata exchange, together with an open-source ecosystem of software tools, the SDMx Global Registry, the Validation and Transformation Language (VTL), a RESTful API specification, and the SDMx Test Compatibility Kit. The offering is targeted at national statistics offices, central banks, and international organisations to standardise, automate and modernise official statistical data operations. The standard and core tools are provided free of charge and governed by a consortium of eight sponsor organisations.

Product overview

SDMx is an open international standard ecosystem (ISO 17369) comprising software tools, educational materials, methodological guidance, and global community support for statistical data and metadata exchange. The portfolio includes the core SDMx Standard for data structuring, the SDMx Global Registry as the central repository for Data Structure Definitions, the Validation and Transformation Language (VTL) for data validation and transformation rules, the SDMx RESTful API for programmatic access, and the SDMx TCK for API compliance testing. These products work together to enable national statistics offices and central banks to standardise data operations, deliver high-quality data products, and prepare data for AI-readiness.

Products and services

• SDMx Standard The core international standard (ISO 17369) for statistical data and metadata exchange, designed for national statistics offices, central banks and institutional organisations to standardise and optimise their data operations. Version 3.0 added microdata and geospatial support; version 3.1 extends data modelling for high-dimensional datasets.
• SDMx Global Registry Web-based IT application containing SDMx Data Structure Definitions (DSDs) and other SDMx objects supporting worldwide implementation of statistical standards. Serves as the central reference point and authoritative source for global SDMx DSDs.
• Validation and Transformation Language (VTL) A standard language for defining validation and transformation rules (operators, syntax, and semantics) for statistical data. VTL is technology-agnostic and usable with SDMx, DDI, and XBRL/DPM.
• SDMx Test Compatibility Kit (TCK) Testing tool that enables SDMx implementers to measure the compliance and coverage of an SDMx RESTful endpoint against available SDMx REST API versions, reporting on compliance levels and feature coverage.
• SDMx RESTful API RESTful web services API specification enabling programmatic access to SDMx data and metadata, supporting SDMX-ML (v1.0, v2.0, v2.1, v3.0), SDMX-JSON (v1.0, v2.0), FUSION-JSON, EDI and XLSX data formats.
• VTL Tools Open-source tools providing editing and calculation features for VTL, with engines implemented in Java, Python, R, and SQL, available to SDMx implementers for executing VTL definitions.

Scale indicators6 records

Recent moves6 records

Expansion highlights5 records

Direct peers

• XBRL International: XBRL International is the standards body for business and financial reporting, similar to SDMx for statistical data. Both are open, ISO-aligned standards maintained by international consortia serving regulatory and financial reporting use cases, with comparable governance models.
• Open Geospatial Consortium (OGC): OGC develops standards for geospatial data interoperability, comparable to SDMx's role for statistical data. SDMx 3.0 added geospatial support, indicating direct overlap in addressing geo-referenced statistical datasets through international consensus-based standards.
• DDI Alliance: DDI Alliance maintains the Data Documentation Initiative standard for social science data, directly comparable to SDMx's metadata management focus. VTL explicitly supports both SDMx and DDI, indicating technical overlap and shared customer base in research and official statistics.
• HL7 International / FHIR Foundation: HL7/FHIR maintains international standards for healthcare data exchange with similar multi-stakeholder governance and ISO alignment. Both address structured data interoperability for institutional users (hospitals vs. statistical agencies) using standardized formats and APIs.

Broad incumbents

• ISO (International Organization for Standardization): ISO is the parent organization that published SDMx as IS 17369. Comparable as the umbrella standards body, though ISO covers thousands of standards across all industries rather than specializing in statistical data exchange.
• W3C (World Wide Web Consortium): W3C is a broader standards organization covering web data formats (RDF, JSON-LD, SKOS) that SDMx draws upon for its semantic layer. While not a direct competitor, W3C's foundational data standards increasingly overlap with SDMx's metadata management capabilities.
• GS1: GS1 maintains global standards for supply chain and product data (barcodes, EPCIS), with similar multi-stakeholder governance and global mandate. Comparable in scale of adoption and institutional backing, though addressing commerce rather than official statistics.
• OASIS Open: OASIS develops open standards across multiple domains (security, IoT, cloud) with a similar consortium governance model. Comparable to SDMx in producing vendor-neutral specifications adopted by government and enterprise, though covering a broader portfolio rather than specializing in statistics.

Others

• IETF (Internet Engineering Task Force): IETF develops internet standards including data formats and APIs. SDMx's RESTful API specification draws on IETF conventions, making IETF an enabling standards ecosystem rather than a direct competitor in statistical data exchange.

Emerging players

• OpenAPI Initiative: OpenAPI Initiative maintains the standard for describing REST APIs, relevant as SDMx provides a RESTful API specification for statistical data. Represents a broader technology trend toward standardized APIs that could either complement or compete with SDMx's domain-specific API approach.
