I am assigned on a project from my company which will use HL7 to communicate with health care
department using HAPI. It will be exchanging of messages between them, means an XML sender and
an XML receiver.
I want to start the POC as soon as possible and end it. Please help me with some initial pointers from where
to start and how to progress as i know nothing about HL7 except its some protocol.
