Issue

Upon receipt of a Batch (a Transmission with a Batch-class entry point) the receiver doesn't know whether it should process its contents in a sequential fashion, or whether the contents can be processed in a paralel (or even random) fashion.

Recommendation(s)

• Add an optional contentProcessingMode attribute to the RIM Batch class (data type CS CNE) to indicate the type of content processing that the receiver of the batch is expected to undertake, i.e., sequential or parallel. Default value is sequential.
• Create a new ContentProcessingMode vocabulary with 2 values:
  • sequential: the content should be processed in a sequential fashion
  • parallel: the content may be processed in a non-sequential fashion

Note: a boolean would suffice at the moment (sequential or not), there may however be use cases for other content processing modes.

Rationale

The behaviour of receivers when processing Batches was "subject to site agreement" in HL7 v2. Various proposals will be (and have been) made to allow a sender to specify the behaviour of the receiver in an explicit manner.

Recommended Action Items

• Implement the proposed solution
