Subject: HARMONIZATION - CQ Proposal for March

Karen,

Please add the issue below to the list of CQ Harmonization items for the March 2005 Harmonization meeting.

TTYL,

-Rene

Issue: "Batches"

CQ has two requests:
1. Move the versionCode attribute from the Message class to the Transmission class.
2. Move the interactionId attribute from the Message class to the Transmission class.

These changes allow versionCode and interactionId to be used in both Message and Batch.

The first item is motivated by the need to have a versionCode in the batchwrapper, in order for the receiver to know what attributes the Batch class has.

The interactionId is desirable for reasons of consistency; batches (like accept NAKs) will have a fixed interactionID, batch acknowledgements (itself a batch) will have a different interactionID.

Background information related to Batches and Batch acknowledgements can be found in CQ Proposal 601, see the CQ documents download page. Batches are slated to be included in R2 of the MCCI domain.
