How can I model data objects in the web designer?

Afaics, data objects have not been added to the modeler yet - nor are they currently planned.

I was out on medical leave all last week, and plan to take another look this week.

I started reviewing the code and it appears some remnants remain for the initial integration (i.e. data constants are defined in json converter project). I am not sure yet how to extend the stencil set. The previous version included detailed properties in the JSON file, but I don’t see anything similar in the latest implementation. I am not sure what the difference is between a Complex property type and a multicomplex.

I have found some resources as follows:

And here is a link to my previous work with the initial implementation:

I made significant progress today and will open a formal issue tomorrow.
