Interface   -   [1] In computer science an interface is a hardware or software tool to enable input or output communication between one system and another, typically via a standard protocol. [2] In health information exchange most clinical data interfaces are software scripts built with standard communication protocols. For example Redwood MedNet uses the open source Mirth Connect interface engine, which uses JavaScript to choreograph the handling of clinical messages received from a sending software system or sent to a receiving software system.   See Computer Science, Informatics, Interface Engine, ISO, JavaScript, Open Source, Protocol, Standard, W3C
