The French National Institute of Statistics and Economic Studies (Insee) has developed a metadata-driven survey data collection process including a questionnaire generator code-named Eno ). This tool operates on a formal description of a questionnaire in DDI and executes a completely automated chain of transformations to produce the actual collection instrument(s) (web and paper forms, interviewer questionnaire) and their documentation.
Eno is interfaced with a questionnaire design visual tool, code-named Pogues, that produces the DDI description of the questionnaire which is then submitted to an embedded instance of Eno. Using Pogues, survey managers and questionnaire designers can specify their web, paper and interviewer questionnaires in a friendly way and visualize the generated results in one click.
Pogues and Eno are open source and internationalized.
