SDMX SDDS

Statistical Data and Metadata eXchange (SDMX) is an ISO standard (ISO 17369:2013) designed to describe statistical data and metadata, normalise their exchange, and improve their efficient sharing across statistical and similar organisations. It provides an integrated approach to facilitating statistical data and metadata exchange, enabling interoperable implementations within and between systems concerned with the exchange, reporting and dissemination of statistical data and their related meta-information.

It consists of:

• technical standards (including the Information Model);
• statistical guidelines;
• an IT architecture and tools.

SDMX is not just a format for data exchange. Taken together, the technical standards, the statistical guidelines and the IT architecture and tools can support improved business processes for any statistical organisation as well as the harmonisation and standardisation of statistical metadata.
