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:

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…
