Implementing DDI Profiles at a National Statistical Office: Experiences at INSEE and ABS

Practical experience using DDI in large statistical organisations has led to the conclusion that DDI profiles are an essential tool for both modernising the statistical production process and facilitating sharing of technical tools and processes.

Both INSEE (Institut National de la Statistique et des Etudes Economiques) and ABS (Australian Bureau of Statistics) are part of the DDI profiles team (sub-group of the DDI/GSIM - Generic Statistical Information Model - mapping group) under the auspices of UNECE (United Nations Economic Commission for Europe), which aims at creating profiles for particular parts of the DDI lifecycle.

  • INSEE has been modelling survey questionnaires using the DDI lifecycle information model for more than two years. INSEE originally used version 3.1, but due to lack of some objects specific to business statistics, such as question grids, has been moving towards adopting version 3.2.
  • The ABS has adopted DDI as a key enabling standard for describing metadata, for use in the development of the next generation of statistical infrastructure. The ABS is implementing version 3.1. of the standard, with extensions where necessary.

This presentation will explain the DDI profile experience for Survey Instruments at INSEE, and for Variables at ABS.
