4
OECDs SDMX work

• Trying to generalise formats across domains
• away from stove-pipes
• Using SDMX in and out of OECD.Stat
• SDMX web service
• Joint External Debt Hub with BIS, IMF, WB
• NAWWE
• ComTrade with UNSD
• Data sharing with IMF (and other IOs)
• Education with Eurostat, UNESCO
• Country pilots data collection

5
Rationale

• The idea
• web based mechanism
• report internationally agreed set of data
• allow any authorised user to access data
• international organisations agree
• Benefits to country's NSO
• One format and one operation for reporting
• Automated generation of data from source
• Built-in validation
• Benefits to international organisations
• Timely reporting
• Complete reporting
• No code misinterpretations

Prototype V1
Web Interface

• Data selection criteria is driven from the
  Structural XML

• Data content is driven from the copied NSO XML
  data files

• Dimension criteria and countries can be combined
  for output

8
Joint Eurostat/OECD questionnaire

• Contains 48 tables
• New version starting 2007
• To be used by OECD from 2007
• Yet to be formally adopted by EU

9
The NAWWE schema

• http//stats.oecd.org/nawwe/
• SDMX-ML v/2 generic message
• with 17 common dimensions table no.
• codelists based on international standards
• Will accommodate yearly as well as quarterly
  national accounts
• But limited now to annual accounts

10
Status early 2007

• Countries Australia, Canada, US, New Zealand
• Organisations OECD, ECB, IMF
• Almost final specification of questionnaire end
  2006
• Data Structure Definitions for all tables
• but only 11 of them specified as tables
• Metadata Structure Definition
• using SDMX Cross-Domain Concepts

11
Next steps

• Four countries expected to report early 2007
• BEA already shows many OECD tables on its web
  site www.bea.gov/bea/dn/sna/sna.htm
• Process
• Adapt these tables to new questionnaire
• Replace these tables by NAWWE tables

12
Conclusions

• Technical questions under control
• Content is the challenge
• E.g. development of questionnaire
• Agreeing among IOs difficult
• But potential gains in efficiency and quality are
  great
