Select the JSON or FHIR demonstrations
The Java Script Object Notation (JSON), and its health adaption, Fast Healthcare Interoperability Resources (FHIR), are popular conduits for the transmission of data over the Internet.
This JAVA JSON demonstration reads a JSON file, which contains real time weather measurements, from the Australian Bureau of Meteorology's (BOM) site for a selected town.
The demonstration also calculates the real time Fire Danger Rating (FDI) for the town and the number of days since it last rained.

The HAPI-FHIR demonstration is a test server which I use to experiment with patient bundles,that is, synthetic patients in my synthetic hospital.
I write clients to do client CRUD functions mainly to understand FHIR bundles.
