See Transmission Wrapper (new wrapper mechanism) for a discussion of the new wrapper mechanism.
Glossary definition: A Transmission Wrapper includes information needed by a sending HL7 Application to package and route the V3 interaction to the HL7 Application which is the designated Receiver. This wrapper also includes attributes that influence the message handling behavior of the receiving application. All HL7 Version 3 Interactions have an appropriately configured HL7 Transmission wrapper.
See Message Wrappers section of the v3Guide for a high level desciption of Transmission Wrappers.
The HL7 Transmission Wrapper exists to two different forms:
- The Message Transmission Wrapper. This wrapper contains zero or one instances of HL7 Transmission Content.
- The Batch Transmission Wrapper. This wrapper contains zero or more Transmission Wrappers (either Message Transmission Wrappers or Batch Transmission Wrappers).
An interaction that has the Message Transmission Wrapper as its "outermost" wrapper is commonly referred to as a Message or a Message Based Interaction. An interaction that has the Batch Transmission Wrapper as its "outermost" wrapper is commonly referred to as a Batch or a Batch Based Interaction.
