We are attempting to "Repoint" old class data to new class data to save disk space and data redundancy across multiple tables. This works to a point. In essence the two classes are sharing the same data / Index / stream globals. But if an ID in the Old_Class is opened, a property is modified, and saved the property that is in the New_Class (but not in the Old_Class) is NULLed / blanked.

I believe a specification-first approach is an excellent idea for API development. IRIS already has features for generating an implementation stub from a specification and publishing that specification for external developers (use it with iris-web-swagger-ui for the best results). The remaining important thing not yet implemented in the platform is the request validator. Let's fix it!

Here is the result of the experiments.
