Introduction to SDMX Seminar Eurostat/ECLAC 02 October 2012 August Götzfried Head of Unit, Eurostat B5 Management of statistical data and metadata
The exchange of statistical data and metadata is complex, resource intensive and expensive; In the past, national and international organisations had developed specific approaches and solutions; Opportunities and challenges related to new technologies such as XML, web services… for machine to machine exchange were coming up. SDMX is the Global answer to this. The background: Why SDMX ?
World Bank UNSD SDMX Statistical Data and Metadata EXchange 3 02-Oct-2012
The 7 international organizations have joined forces, with the effect of: Memorandum of Understanding signed March 2007 A rotating chairmanship every two years UN Statistical Commission 02/2008: SDMX is recognized as “the preferred standard for exchange and sharing of data and metadata in the global statistical community” Further involving national and international statistical agencies Importance of capacity building and outreach (webpage, seminars, workshops, training…) More freely available IT tools……. Why is SDMX so important?
SDMX is the crucial instrument for rendering the production method of EU statistics more efficient → new Eurostat vision After a phase of low investment the burden on national and international statistical organizations is in general reduced. Data and metadata messages produced by national and international organizations get more comparable and consistent. National and international statistical processes get more harmonized and offer new ways of data and metadata exchange (such as data hubs) Web-based dissemination formats are provided that are computer “readable” and easier to update. Benefits of SDMX
Costs of SDMX Development/maintenance of the SDMX standards and guidelines done by the international sponsoring institutions (supported by NSIs) Standards are public and open source IT tools are created by sponsoring or other organizations and made freely available Capacity building by individual sponsoring institutions Input to the SDMX standards from the user community through open process No need to radically change the IT and statistical systems: gradual SDMX implementation possible with low investment costs
