Insee has been developing during the last years a metadata-driven survey data collection process including a questionnaire generator code-named Eno. This tool operates on a formal description of the questionnaire in DDI and executes a completely automated chain of transformations to produce the actual collection instrument(s) (web and paper questionnaires). The questionnaires can be personalized and, depending on the output format, a variable amount of flow logic can be implemented.

Questionnaires from 30 different business surveys have been produced by Eno, and this number will continue to increase, especially because Eno will soon support questionnaires for household surveys.

Interfaced with Eno is a questionnaire design user interface, code-named Pogues, that connects with the generation process. More specifically, Pogues produces the DDI description of the questionnaire which is then submitted to an embedded instance of Eno. Using this tool, a survey manager or questionnaire designer can specify his web, paper and soon interviewer questionnaire in a friendly way and visualize the generated result in one click.

Pogues and Eno are open source, internationalized, and thus can be used directly by other statistical agencies. They are currently using DDI version 3.3. Some have already shown their interest.
