Global Data Structure Definitions (DSDs)
  • Since 2011, SDMX has brought together the technical 
   and statistical world in several domains to work on 
   DSDs for global use
  • Global DSDs improve many aspects of data exchange 
   for the whole statistical community, such as:
   – Better timeliness by allowing data queries (pull) at the point 
    of dissemination
   – Avoid the burden of maintaining many different reporting 
    systems and exchange agreements
   – Save money by reusing IT systems, standards, and 
    methodology
        Global DSDs as Enablers
   Immediate benefits:
     – Agreed reporting structures across international community
     – Guidelines for implementation allows easy understanding and 
      implementation
     – Clear for reporters how to provide the data using free SDMX 
      tools
     – The SDMX Global Registry is already available for storing the 
      Global DSD artefacts, and a great tool for testing, piloting and 
      production rollout
         Global DSDs as Enablers
   Some benefits became clear later:
     – Global DSD governance framework has proven to be very effective
     – SDMX design approach is reusable and is now a SDMX guideline
     – A harmonised reporting framework (the Global DSD) allows working 
      groups that are focused on implementation
     – The agreed maintenance cycle makes it much easier to manage changes 
      for Global DSD maintainers and adopters
     – Better links are possible to other statistics
     – Allows a “cascading” data collection model
       • Avoids reporting same data to different organisations
       • Ability to report to one organisation who can forward it to the relevant 
        organisation
          Global DSD History: National Accounts
       •    First Global DSD in production (2013 Q3)
       •    ECB, OECD, Eurostat (project manager), in the working group:
             – Design the reporting structures (DSDs)
             – Create guideline documentation for pilot and implementation
             – Respond to change requests from the international community
       •    Shares many aspects with other Global DSDs
             – Code List, Concept sharing
             – Reusable design principles
             – Reusable  governance and maintenance principles
             – “Macro-Economic Ownership Group” makes decisions on National Accounts, BOP, FDI, GFS
                   •  Makes decisions on recommendations from technical group
                   •  Environmental Economic Accounts (SEEA) will be in the SDMX-MES
       •    SDMX implementation task force for International Data Cooperation (TFIDC):
             – Design efficient data flows between organisations 
             – Pilot the technical implementation of the Global DSD
             – Put the Global DSD into production in an internationally coordinated manner
