• Data quality • 1 country 1 year 1 GDP
• Shared validation rules
• Shared responsibilities
• Lowering reporting burden • 1 data flow from

Concepts and Code Lists
• 2 global SDMX implementation projects
• …for National Accounts (SNA2008 / ESA 2010)
• …for Balance of Payments (BPM6) and Foreign Direct Investment (BMD4)
• 2 project steering groups and 2 technical groups
• Running from 2011 until 2013
• Publication of V1.0 DSDs in September 2013
• Steering groups Ownership Group
Background
• Mandated by SDMX Sponsors in January 2014 • As a single OG for NA & GFS, BOP and FDI
• Representation of management from content and SDMX side
• Oversees maintenance of SDMX artefacts • Mandated technical groups
• 1 on BOP and FDI; 1 on NA and GFS
• Close cooperation with IAG Task Force
international data cooperation (TFIDC)
Ownership Group (OG)
Maintenance Agreement
• MA will only apply changes agreed upon by OG
• Change requests may lead to…
• Structural changes: major release (e.g. SNA2025 )
• Annual maintenence release (regular case)
• Fast-track maintenance release (only for small changes limited to selected dataflows) (subject to review during next annual release)
State of Play
• V1.1 published in Jan 2014 • V1.2 in April 2014 in SDMX Global Registry
• V1.3 fast-track release for NA Sector Accounts (to fix a mistake in one code list)
• V1.4 regular release currently in preparation • Support for coding Euro Area 19 • Inclusion of IMF GFSM coding • Support for SNA93 in the context of international
data cooperation • Support for additional dataflows (e.g. GNI, EDP) • Minor additions to existing code lists
• Next OG meeting: November 2014
SDMX-NA Governance
• Maintenance Agency: Eurostat
• Ownership Group:
• Active: ECB, Eurostat, IMF, OECD, UNSD
• Passive: BIS, World Bank
• Published in the global registry:
• http://registry.sdmx.org
• Annual maintenance cycle (April-April)

International Data Cooperation Background
General objectives • Reduce reporting burden on NSIs
• More efficient use of resources in
International Organisation (IO)
• Ensure high quality and consistency
of data of official statistics
• Improve global data exchange and dissemination
SDMX provides • technical/statistical standards
• new exchange modes (hubs)
• clear rules and responsibilities
SDMX Web Services
A possible data sharing model
EU OECD
other than EU World other than OECD
Eurostat - ECB
OECD
IMF, UN, WB, BIS, other IOs
U S E R S
The necessary pre-conditions
• SDMX maintenance agreements Ownership and maintaining agency to be defined (normally between the international organisations)
• Internationally agreed data validation
Data validation rules and SDMX data validation standards (beyond file structure validation)
• Streamlined data exchange processes Frequency and timeliness for data dissemination, data quality management etc.
International Data Cooperation in National Accounts
• IAG: Interagency Group on Economic and Financial Statistics
• BIS, ECB, Eurostat, IMF, OECD, World Bank
• same organisations as SDMX Sponsors
• IAG Task Force International Data Cooperation
• TFIDC, co-chaired by Eurostat and IMF
• Pilot 1 on GDP and population
• Pilot 2 on Sector Accounts
TFIDC – State of Play
• Pilot 1 on GDP and population
• Data flow template agreed, based on NA_MAIN DSD
• Monthly data exchange, senders: Eurostat, OECD, IMF
• Some minor technical issues: e.g. SDMX header compatibility SDMX TWG
• Go live planned for Q1/2015
• Pilot 2 on Sector Accounts
• First tests successful, based on NA_SEC DSD
• Lessons learned from pilot 1
• Pilot to kick off Q1/2015
TFIDC – Next steps
• Agreement on detailled validation rules • Eurostat / OECD agreement as basis
• Support for SNA 93 data exchange • Change request pending in Ownership Group
• Improvement on data exchange frequency • Monthly PUSH not enough to meet objectives
• Discussion on future topics • Plans for dissemination using global DSDs
• PULL mode, improved data coverage…
