We introduce the metamodel as a new modeling framework for design
objects based on General Design Theory, a mathematical model of design. Using
General Design Theory, the metamodel concept can serve three functions: (1)
as a central modeling mechanism to integrate models, (2)as a mechanism for
modeing physical phenomena, and (3) as a tool for describing evolving design
objects. Modeling with multiple points of view is realized by representing
physical phenomena that occur in the design object and by constructing models
with knowledge of physics and design from tne metamodel. We illustrate the
first and second functions of metamodels with an example based on naive
physics, and we illustrate the third function of the metamodel through design
experiments. Finally, we present two systems to illustrate how the metamodel
mechanism can be implemented.
