National Accounts World Wide Exchange Progress Update – Russell Penlington (STD) October 2003
Rationale: Capitalise on Standards National Account standards exist already: • SNA93 defines a standard for national account statistical data • NSOs submit Excel tables in a standard coding and format Data Dissemination standards exist already: • XML is an non-proprietary standard for transmitting data between applications and organizations • SDMX is an XML standard for defining, transmitting, validating, and interpreting statistical data between organizations NAWWE attempts to capitalise on these standards to: • Enhance national account data collection at the OECD • Provide other international organizations the same benefits • Facilitate data sharing and dissemination processes for NSOs

Prototype: 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
Progress Update: Project Status XML Schema and File Structures: • Structural and Data XML schemas based on SDMX standards • New Excel macros distributed to pilot countries Web Application Interface: • Automatic checking of remote server Data XML file updates • Utilization of Structural XML for navigation & metadata display Next Steps: • Modify and refine XML schema as SDMX version 1.0 eventuates • Enable notification of XML file import status (NSOs & STD staff) • Provide XML output functionalities (Excel and database upload) • Integration of user functions (validation, output, upload) OECD Development Team: Valerie Thielemans, Eric Dery, and Russell Penlington
