Abstract
SDMX (Statistical Data and Metadata Exchange) is a standard used successfully by the international statistics community. In data exchange, SDMX has replaced numerous individual agreements and enabled the development of so-called data-driven systems.
But the real potential of SDMX lies in its use as a classification system for any—and not only—financial and economic data. Many institutions use SDMX for data collection, data provision and Internet publishing. A real-life example of a mature SDMX solution is the IMF’s (International Monetary Fund’s) “Special Data Dissemination Standard Plus” initiative.
At its core, SDMX is amazingly simple: a data set is modelled by identifying and encoding its defining dimensions, i.e. the axes of its coordinate system. Each individual data point from this data set is then uniquely determined by its coordinates: the SDMX key. By sharing specific dimensions between different topic areas, an SDMX landscape of linked topic areas emerges.
