What high-level problem are you trying to solve?
Forms can be available in many languages, which is great. But often, researchers would like to know what language the form was filled into:
-
To use as a data point for data analysis (e.g., preferred language)
-
To know what language to use to reach out for follow-up surveys
-
To know whether some translations can be discarded for future projects (i.e., if not used at all)
-
To use within the form for skip logic and calculations
Any ideas on how ODK could help you solve it?
Adding a metadata field (e.g., form_language) that tells you what language was used for data collection. This field might evolve throughout the submission process, if users toggle back and forth between languages, which would be reflected if the field is used for form logic, but ultimately only the last selected language would be recorded in the data.
