3. Announcements
- Several at HL7 meetings in Phoenix. Ken; asked about CP 97 – static and dynamic use for OBX-4, the more we talk the more confused we become. Jeff M; If there's more concerns, we should discuss it more, maybe constraining it to the pumps. Ken; some questions about dynamic and static issues. John G; rules and testing must be considered for single device and gateways with multiple devices. He suggested several folks and meetings of a “tiger team”. Have to accommodate several modes, are we doing a good job capturing correct data from devices and gateways. Will require a group to address this, with senior participants to focus on the needs. Hope to describe generally in the TF, then describe constraints in implementation guides, content modules, special Vol 2 modules. Members: Todd, Chris C, Ken, Paul Sc. Could be a topic on Thursday Standards and Tooling meetings. Paul E; some met after last weeks call, he sent notes to Paul Sh.
Action – Paul Sherman will send a request to the PCD group organizing discussion of CP 97 and OBX-4.
Action – Form a 'Tiger team' to work on it.
4. Status: TF, Supplement, Other Documents
- Ballot to Modify DEC NK1 Segment PCD CP grid CP 102.
Out for Ballot now. Pretty small in scope, simple. Didn't have a use case that required it until now. Have 3-4 votes now, another 8 or so, we'll be in good shape.
- Discuss CP 101
First comment – Doesn’t EUI-64 need to be required for certification? Yes, but until then, if running ethernet, can have a derived EUI-64. Monroe suggested that other unique identifiers could be used in a testing environment, but not for certification where the application must be unique and in an installation the individual device must be unique and can include the MAC address. If it's in an app, then the EUI-64 is instance unique. Don't believe it's instance unique. Need to be clear on EUI-64's intent. Todd – doesn't recall a division, believes it's a source device identification. If you have a NIC, then there's a unique identifier. May not apply to DEC. Background: DNS3 was using another ID, PCD has decided to use EUI-64, wanted to resolve conflict. Will need to work out a Connectathon table – need to know this prior to testing. Does EUI-64 need to go through IEEE? John R – had to think about design goals, some goals; Definitively ID info source (trouble with RS232 devices); for gateways, will need source ID, not just gateway ID. John G – needs to be predetermined or derived from the message. Need it established before the Connectathon, and maybe Pre-Conn. Validation requires having pre-defined identifiers for testing and they need not all be EUI-64 for this purpose. Do we have what we need to validate? John R – real world deployment will be an issue as well. John R - CP takes away DNS option, which is good. Jeff M – Needs reworded, to include NIC based EUI-64.
Other comments –
o Spelling,
o RS 232 legacy devices, how does this get resolved (gateway devices)? No simple answer. John G – whatever identifier to use, if we have a table with any format, we can validate the tests.
o Jeff M will follow up with Ken on serial/legacy comms, how to resolve it. Plus need language to clarify EUI-64 sources.
