OECD’s SDMX work • Promoting SDMX as the world standard • 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

  3. 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

  5. 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

  6. 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

  7. 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

  8. Status spring 2007 • Countries: Australia, Canada, US, New Zealand, Mexico • 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

  9. Next steps • Four countries expected to report 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
