For simplicity, we discuss two: PrimaryData as a HashMap of key-value pairs that drive the display model, and FocusedEntity, which represents the current tag under focus.
Each of the items under MyProcess represents a category of additional resources that you can add to your process model (except for the last one, which represents the process itself).
Like all models, this represents a simplified view of reality: there are no intermediate states under development for example, since the definitions of such states are subjective and ambiguous.
