3 Agenda Items
- As Noted
3. Connectathon Technical Followup, issues found during the Connectathon:
- MSH-10 Message Control ID: John Garguilo noted that device IDs need to be unique in messages and acknowledgements. Referring to the MSH-10 Wiki page (link above), Al believes that item 4 means that the combination of the sending application and the device identifier will provide a unique value. Jon Blasingame asked if an adjustment will be required for messages that leave or enter from other domains’ messages. Further, Al suggests that some additional data will be required, such as time or sequence number. Khalil indicated that uniqueness must be maintained even when the system is reset. He asked if a “resent” message will need to have a new, unique ID. Al responded that the purpose is to associate the sent and ACK/response messages. John Garguilo suggested that constraining the HL7 requirement will make testing with the NIST tool possible – if this adds value. Al noted that a change now could incur significant validation costs in product development. Al noted that MSH-3, 4, 5 and 6 are optional in HL7 v2.6. John Rhoads noted that item 4, requiring MSH-3, is a PCD constraint. Sandra noted that MSH-3.1, 3.2, 3.3 are required.
- MSH-21 Entity Identifier: This is required for the message but not for the ACK. MSH is only defined once. Al believes that is doesn’t make sense in the ACK. John Rhoads asked if clarification in the TF would be worthwhile for MSH in acknowledgements. Al responded that it would be difficult to do within the table, and there are other items, e.g., MSH-13 and MSH-15 where notes would be helpful.
7. Event Notification: John Garguilo asked if Alarm Communication can become a subset of a larger profile that would include events. Monroe expressed the view that Event Notification will broaden the topic. John Rhoads indicated that there are different processing mechanisms, e.g., alarms are directed to a person. This discussion can continue in the ACM WG meetings.
9. May F2F: Moved to the second week. Manny will poll to learn if the move will prevent anyone whose presence is essential to PCD efforts from coming or joining a Webex for portions of the meeting.
