SDMX for Human Health and Population Distribution

SDMX, which stands for Statistical Data and Metadata eXchange is an ISO standard (17369:2013). It is designed to describe statistical data and metadata, to normalise their exchange, and to enable them to be shared more efficiently among organisations. SDMX has three key components: I) a information model to describe data and metadata; II) a standard for automated communication  and III) an IT architecture and set of tools for data and metadata exchange

Relevance & expected benefits: 

Statistical data are stored in a structured harmonized approach. Code list are stored in dedicated registries. By using SDMX data directly for INSPIRE several advantages are achieved: e.g. usage of semantically harmonized data, storing and updating data only once and leaving data at its source avoidance of duplication of transformation, synchronization issues across datasets, publishing machine to machine readable data.

Outcome: 

Reuse already existing statistical data provided in SDMX (ISO 17369:2013).

Evidence: 

Several reference implementations of SDMX are available for usage are available. Official sponsors and users of SDMX are the following organisations: Eurostat (the Statistical Office of the European Union); Bank for International Settlements (BIS); Organization for Economic Co-operation and Development (OECD); European Central Bank (ECB); International Monetary Fund (IMF); United Nations (UN) and The World Bank Group (WB).

 
Limitations: 

Any organization providing data using SDMX must map their internal data structure into the SDMX information model.
