INM Pre-May WGM out-of-cycle Meeting

From HL7Wiki
Jump to navigation Jump to search

INM has held an out-of-cycle meeting (the board has approved it) related to Transmission and Transports in San Antonio immediately prior to the WGM.

Topics

The intent was to do mini-harmonization for the Transmission and Transport domains, and in addition, to find solutions for some of the festering issues that exist in the overlapping areas between these areas. These issues are long running issuesthat do not fit well into the ballot process, and we have been struggling to find time or a process to give them any substantial consideration.

There are a large number of outstanding issues. Generally,there is a scope question relating the concept of interactions, transmissions, transports, how they inter-relate with each other, and how the historical HL7 approach relates to approaches taken in other industries or by other standards bodies (note that we use these other standards for actual transport).

See below for the agenda; also see the list of confirmed attendees.
