The IT Infrastructure Domain supplies infrastructure for sharing healthcare information. An infrastructure interoperability component represents a common IT function that is used as a building block for a variety of use cases... a necessary ingredient, but rarely visible to the end user!! These components may be embedded in an application, but are often deployed as a shared resource within a RHIO or Health Information Exchange.
