SDMX and the e-GDDS
The Statistical Data and Metadata Exchange (SDMX) standard underpins much of the operation of the enhanced General Data Dissemination System (e-GDDS).
e-GDDS recommends that participants establish a National Summary Data Page (NSDP) on the Internet, which links to electronic SDMX data files for each of the e-GDDS data categories. Once e-GDDS participants disseminate data via the NSDP, IMF staff use automated SDMX-based processes to assess progress against the core data categories, making reference to periodicity and timeliness, in an annual report and a brief semiannual update.
SDMX is an international initiative that aims at standardizing and modernizing (“industrializing”) the mechanisms and processes for the exchange of statistical data and metadata among international organizations and their member countries.
SDMX is sponsored by seven international organizations including the Bank for International Settlements (BIS), the European Central Bank (ECB), Eurostat (Statistical Office of the European Union), the International Monetary Fund (IMF), the Organisation for Economic Cooperation and Development (OECD), the United Nations Statistical Division (UNSD), and the World Bank.
