Sender

HL7 Messaging Architecture

A Sender in the context of HL7 embeds the sending HL7 Application and the Messaging Adapter responsible for Messaging Protocol configuration. A Sender implements business rules according to the HL7 Trigger Event and Interaction definition, and prepares the HL7 message for the delivery facilitated by the Messaging Protocol in the Messaging Infrastructure Layer.

Notes

• Question: "Why do we embed Messaging Adapter in the concepts of the Sender and Receiver as well?"
  • Answer: "The reason why we have included the Messaging Adapter to the Sender and Receiver is very simple - without the Messaging Adapter the HL7 Application, which is able to produce and consume HL7 message (including object representation and serialization using the ITS) is not able to send the message anywhere, so no point of calling something "a Sender" where there's no sending or receiving associated to it.
