INM workitem.gif

This page documents an INM Workitem, i.e. an issue within scope of the INM Committee that either is still being discussed, or the resolution of which has not yet been included in an INM ballot.

Is there a need for a general mechanism for Fragmenting Large Transmissions (messages as well as batches). The UK uses a max. 25Mb size of individual transactions.

  • 20060510 WGM: Motion "The INM committee decides not to support a mechanism to fragment large messages. Any fragmentation for transmission/transport purpose should be dealt with within the Message Infrastructure Layer. The receiving HL7 Application has the option of refusing an interaction because of its size." (Motion by Rene/Miroslav, 13-1-0).
    • Discussion: Miroslav: fragmentation is present in v2 (as a site negotiation option), problematic in v3. Fragmentation is a post-serialization ITS specific issue. Document that MIL may support fragmentation in the ATS document.
