A June blog post by Keith Boone (aka @motorcycleguy), Convergence: CEDD, CIMI, IHE, FHIR, hData, HL7, mHealth and ONC got me thinking and sketching this simple diagram of how some of those pieces can fit together.
It's more stream of consciousness than companion diagram, but there it is. A REST client/server wrapped in consent rules wrapped in security protocols (only client side shown), treating health information as RESTful resources. A URI for each patient, document, and fragment.
The other thing that stuck out to me is the fact that we need data structures which can be use by both simple clients and highly complex ones. Where a mobile app may be reading and writing a half dozen data poings per entry, an industrial strength medical information system may be processing hundreds, and yet they operate on the same record. That's the essence of the CDA XML to hData JSON downshift, to allow interoperability between devices of vastly different capability.
