This document discusses strategies for handling JSON data and transformations between JSON and case classes in Scala. It notes that case classes can be used as data transfer objects to represent JSON but are not updated in place. Transformers are suggested to handle conversions between different case class representations of JSON data while avoiding issues with implicits and maintaining immutability. Using traits to avoid duplicated code and avoiding enumerations are also briefly mentioned. Contact information is provided for those wanting to learn more about these strategies.
