1. QCAT integration

• index: [prefix][questionnaire_type] (examples: qcat_technologies, qcat_approaches).
  • The prefix can be set in the settings.
  • The index is actually an alias pointing to an index in behind (for example qcat_technologies_1). This allows to update the mapping of an index without any downtime (see also https://www.elastic.co/blog/changing-mapping-with-zero-downtime).

• type: questionnaire. This is currently always set to questionnaire.

• id: identifier. The identifier of the questionnaire.
