Statistical Data and Metadata eXchange (SDMX)

by SDMX

SDMX is an ISO standard 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. SDMX documentation consists of technical standards (including the Information Model), statistical guidelines, and an IT architecture
