Hi Rudi,

HL7 is indeed THE standard used to communicate patient data in a hospital (is implemented by all major vendors).

You can find a good introduction to HL7 on http://secure.cihi.ca/cihiweb/en/downloads/HL7Can_V2xTutorial.pdf

www.IHE.net can also help you to understand hl7 messaging in the hospital workflow.

There are a lot of (free) tools and api's available ... see http://www.hl7.org.au/HL7-Tools.htm

Here are some sample HL7 ADT (admission, discharge, transfer) messages created from my care2x system :
