OMHE (Open Mobile Health Exchange), pronounced "ooommm," is an open-source microsyntax for text messaging (mobile SMS), Twitter®, medical devices, and other "short text capable" systems.
OMHE has a short list of standard messages and commands like
wt=182to transmit a current weight or
getphrto request a copy of your personal health record. The target audience includes cell phone users entering personal info on the go, distributed data collection devices like blood glucose monitors and pedometers, and patient services like personal health records or disease management nurses. I think this idea may have real utility in a variety of settings, and being open-source is a big plus.
