Modelling the contents and structure of official statistics Or: How to design ”correct” and globally consistent SDMX Data Structure Definitions Or: Navigating in a space of statistical surveys of society Or: Reality as a statistical construction Based on a paper by Bo Sundgren, Statistics Sweden ICES-III, Montreal, June 18-21, 2007
