Methods For Mapping Repeating Fields

The following table describes the various methods you could use to map repeating fields:

Method NumberMethodAdvantagesDisadvantagesDetailed Example(s)
1Create a table group.Handles any number of repeats, with minimal mapping.Slightly more complex table organization.Mapping Repeating Fields Using Table Groups
2Map a finite number of repeating fields.Simple tables, which are good if you only care about a small number of values.Does not handle any number of repetitions and requires more manual mapping through the Chameleon GUI.Mapping a Finite Number of Repeating Fields
3Use Python scripting.Less mapping, which allows you to manually map fields using Python.Repeating values are not mapped separately. This approach is not recommended if the data you want has several sub-fields within the repeating field.
