Individually mapping variables can be massively time consuming if there is no existing documentation, and if variables do not match question names. Therefore the following rules have been applied to the mapping:
- Each item (question item, variable or question grid) can only have ONE topic mapping. If the item is such that two topics must be applied, the mapper moves up to the top level of topics or declines to give a topic.
- Items related to one another during the question-variable mapping must have the same topic. Again, if this does not work, the mapper moves up to the top level of topics or declines to give a topic.
