The various sets of BIS international financial statistics, as well as other BIS activities in the statistical area, require the transmission, processing and dissemination of vast amounts of statistical data and related methodological information (so-called metadata).
On behalf of the central banks involved in its statistical work, the BIS is a sponsor of the Statistical Data and Metadata Exchange (SDMX) initiative, together with the ECB, Eurostat, the IMF, the OECD, the World Bank and the UN.
Together with IT service architecture and IT tools, the SDMX technical standards and content guidelines enable data and metadata to be disseminated and shared efficiently. The first version of the standards was finalised in 2004 and has been approved as an ISO Technical Specification (ISO/TS 17369:2005). The most recent version (SDMX 2.1) was approved by the SDMX sponsors in 2011.
