One small (overdue) example.

You can see some early prototypes of detailed clinical models with the Clinical Data Definition work I did with Tolven a few years ago. A reasonable example would be the chest exam which isn't a complete, flushed out, all bells and whistles example, but it gives a basic idea of where we were two years ago.

One of the components, shown here, are the attributes of a heart ascultation finding. It has a main finding, or entry point, (just called Murmur) which has a fairly value set for the Observation.value drawn from a handful of SNOMED-CT concepts which describe the bulk of the murmurs we routinely encounter in practice.
