1. Global SDMX Implementation Experience from on-going projects Daniel Suranyi, Eurostat Project Officer for SDMX implementation SDMX Expert Group, 13-14 September, Paris

2. Challenge: Global DSD Statistical Domain International Harmonisation SDMX

5. Roadmap – National Accounts 20122013 2 014 Preparation Development Consultations Implementation Production & Maintenance Organisation, planning, data flows Domain concepts, draft DSDs, fine tuning Pilot projects, system adaption, release SDMX & NA expert review, acceptance

6. General Approach Definition of domain concepts Grouping –cross-domain –NA & BoP –NA specific Coding Draft DSD Review

7. Reporting matrix into SDMX artefacts Concept Scheme Data Flow Code ListsData Structure Definitions CL Constraints

8. Comparison: Use a single "Global DSD" "Not applicable" code in all dimensions Constraints for sub-setting code lists "Entry gate" problem –Push: validate selection of data flow –Pull: queries more complex Complex validation

9. Comparison: Using multiple derived DSDs No direct reference to "Global DSD" –to concept scheme and code lists Multiple files / identifiers  Push: DSD ↔ data flow  Pull: direct query Maintenance –On DSD level instead of complex mechanisms

10. Use case: reference multiple code lists Reporting Country National Accounts ISO 2 NA Aggregates Research & Development ISO 2 NUTS 2 R&D Aggregates Activity Eurostat NACE 2 Custom Aggregates OECD ISIC 4 Custom Aggregates Currently not possible in SDMX 2.1 –to extend code lists by reference –to reference multiple code lists by concept –to use hierarchical code lists for reporting Current solution –build domain code lists based on COG

11. Statistical Domain International Harmonisation SDMX Messages "SDMX Implementation" ≠ "Global DSD" –Data flows  Concepts  Reporting matrix / code lists –Best practise: domain & SDMX experts from the start A single global DSD per domain is not sufficient –Harmonise reporting needs as far as possible –Additional intelligence around the DSD needed –Derive DSDs, but handle with care Some technical limitations –Common way of using existing possibilities –Foresee in next version of standard
