  1. The Generic Statistical Information Model Steven Vale UNECE steven.vale@unece.org

  2. What is GSIM? • A reference framework of information objects • It sets out definitions, attributes and relationships of information objects • It aligns with relevant standards such as DDI and SDMX • Version 1.0 December 2012 • Version 1.1 December 2013

  3. GSIM: • Provides common terminology across and between statistical organisations • Allows statistical organisations and standards bodies (e.g. SDMX and DDI) to understand and map common statistical information and processes

  4. GSIM is a conceptual model: It is a new way of thinking for statistical organizations

  5. Purposes of GSIM • Improve communication • Enable greater automation • Provide a basis for flexibility and innovation • Improve efficiency • Generate economies of scale

  6. BUSINESS group capture the designs andplans of statistical programmes, and theprocesses that deliver those programmes • EXCHANGE group describes information flowing in and out of statistical organisations, e.g. objects that describe the collection and dissemination of information • CONCEPTS group is used to define the meaning of information to provide understanding of what the data are measuring • STRUCTURES group is used to structure information throughout the statistical process, so that it can be uniquely and unambiguously identified

  9. GSIM and GSBPM • GSIM describes the information objects and flows within the statistical business process.

  10. To get the maximum benefits from standards-based modernisation, implementGSIM together with GSPBM

  11. Mapping GSIM to DDI and SDMX • Detailed mapping between GSIM and the information models of DDI and SDMX. • Evaluate coherence • Resolve unnecessary differences

  12. GSIM Conceptual model SDMX DDI Implementation standards Other relevant standards

  13. Version 1.1 • Simplified - 150110 information objects • Incorporates revised Neuchâtel Model of classification terminology • Better aligned with other standards, particularly DDI

  14. Layers of documentation • Brochures • Top managers • Communication Layer • Conference-type paper for information specialists • Specification Layer • Detailed technical information for implementers
