selfVM.JsonToObjects as described here - Import xml and JSon with MDriven - is available only in ViewModel and will import Json from a string and fill in matching attributes and associations from the model starting from an object that JSonToObjects create based on sent-in type (first argument).

JSonToObjects offer no transformation layer between your Json and your model - things need to share names to match.

The TaJSon strategy is different in that it always uses a ViewModel as a template for both getting and setting data hierarchies to and from json strings. TaJson offers to update object hierarchies in a whole other way than JSonToObjects do as JSonToObjects always create new objects.
