Gateway

A Gateway is an HL7-artefacts aware application which executes business rules, and forwards/ copies/ amends/ transforms interactions (messages or batched messages) based on those business rules. In order to perform those business rules, a Gateway is always an HL7 application that is listed as the receiver of the incoming interactions and sender of the outgoing interactions (just like any other HL7 application).

• Question (Phoenix Action Item, refering to ATS Line item 52) - Are the Gateways always trusted? Is there a use case or a possibility of a highly distributed environment where Gatewys are *not* trusted?
