Issue

The transmissions that form the contents of a Batch (a Transmission with a Batch-class entry point) mostly have the same Sender/Receiver as the Batch transmission itself. This introduces a level of redundancy which some implementers would like to avoid. The RIM currently makes no statement regarding the inheritance of transmission related classes.

Recommendation(s)

Add documentation to the RIM to the effect that Child transmissions inherit all elements of the Parent transmission unless explicitly overridden, such as sender, receiver, attachments, transmission time, etc. This is applicable to (but not limited to) Messages [interactions with a Message-class entry-point] contained in a Batch [interactions with a Batch-class entry-point].

Rationale

Avoid duplication which increases the size of Batches; resolve modelling ambiguity by documenting inheritance for transmissions.

Recommended Action Items

  • Implement the proposed solution

Resolution

20060618 harmonization meeting

Lloyd: add docomuent to association from batch to transmission batch:transmission-transmission:batch. Friendly amendmend.

Charlie: what type of contextConduction (if that were possible on this association) is this? Somethings may inherit where you don't want to.

Open issue: there currently is no mechanism to stop unwanted inheritance.
