Medical Device Workflows in FHIR

Medical device workflow are rich and complex. This design attempts to factor the domain into a minimal set of components that can be combined to produce useful systems. It's self-consciously naïve, but it should serve as a seed for discussion.

A few assumptions and a sketch

• Any device can be online all the time, and can act as a FHIR server -- possible all on its own, or possibly with the help of a proxy/manager/facade component that "fronts for" the device. (Communication between the device and its manager occurs using any mechanism necessary; but the components below be useful for such internal communication, too.)

(EK: The assumption that a device can act as a server, won't that preclude the use of our resources by less powerful devices? I'm just thinking about smaller worn devices, etc. Maybe just posting results somewhere is the max we can expect from them)
