Some time ago, InterSystems introduced the concept of %DynamicObjects.
This feature is a powerful tool that makes it very easy to convert any string of JSON text to objects and vice versa.
However, in the work that J2 Interactive is doing for our customers, there are a couple of things that "need some tweaking".
Very often, we create REST services for our customers. Those services have a payload (in JSON format) that contains information that our customer expects in the form of an object that is proprietary to them.
