  1. Introduction to SDMX Seminar Eurostat/ECLAC 02 October 2012 August Götzfried Head of Unit, Eurostat B5 Management of statistical data and metadata

  2. The background: Why SDMX ? • 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.

  3. UNSD World Bank Statistical Data and Metadata EXchange SDMX 02-Oct-2012

  4. 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?

  5. Benefits of SDMX • 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.

  6. 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

  7. SDMX – opportunities • Across domains • Across organisations • Streamline data flows • Central management (SDMX Registry) • Data structures, concepts, code lists • Software tools • Data sharing 02-Oct-2012

  8. Version 1.0 GESMES/TS Version 2.0 From version 1.0 to version 2.1 ISO/TS 17369 2008 SDMX accepted at UN level SDMX-EDI SDMX-ML SDMX Registry SDMX recognised and supported as the preferred standard SDMX 2.1 Version 1.0 Version 2.0 September 2004 November 2005 February 2008 April2011

SDMX Sponsors • Highest-level Group (Directors,etc.) • Main general SDMX decisions SDMX Governance • SDMX Secretariat • Second-level Group • "Daily" management and decisions • Central consultation for SDMX Members • Statistical Working Group (SWG) • Management of the Standards • Standard SDMX code lists • Nomenclatures • Content-Oriented Guidelines • Technical Working Group (TWG) • Management of the IT infrastructure • Technical Standards • SDMX registry • Webforms
