Messaging Protocol

Definition: Messaging Protocol refers to the rules, formats, and functions implemented by the Messaging Infrastructure Layer for exchanging HL7 messages. Once the message has been assembled according to the HL7 standard, and formatted according to the rules of an HL7 ITS, a meesage gets passed on to the Messaging Infrastructure Layer, which will use Messaging Protocol for the message delivery. Messaging Protocol examples include Web Services, ebMS and MLLP.
Addtional notes:
- messaging protocol term is often used to refer email protocols such as SMTP, IBM's SNADS, etc (see Answers.com). From the HL7 perspective, we refer to these technologies as the application transport (or transfer) protocols, to distinguish the ability of a messaging protocol (such as ebMS) to use any application transport protocol to which the binding is defined (e.g. FTP, HTTP, JMS)
- The messaging system usually includes messaging agents (which in this case would be the HL7 Sender and Receiver), transfer agents and the messaging store that together are facilitated by the Messaging Infrastructure Layer in the HL7 Application architecture.
