GSIM, CSPA, and Related Activities of the High Level Group

Several recent initiatives related to the use of DDI in official statistics are now in progress, under the auspices of the UNECE’s High Level Group (HLG) on the Modernization of Statistical Production. This presentation will focus on the revised Generic Statistical Information Model (GSIM) 1.1, the related Common Statistical Production Architecture (CSPA) and prototypes, and the mapping work relating these to DDI implementation. Relationships to other standards is also presented, including Statistical Data and Metadata eXchange (SDMX), the “syntax-neutral” expression and validation language being jointly developed by DDI and SDMX, and the related process models (GSBPM and its longitudinal equivalent developed by the DDI Alliance).
