Agenda
(Sean) Review last week’s discussion --- largely:
· Rough consensus, working code
· Agreement: we will ultimately recommend a single concrete implementation for the pilot
· (ROUNDTABLE – issues?)
Clarification from Mark Stine
§ Reference implementation software will be utilized for the pilet?
§ Proof of concept code will be first step
§ Wide variety of implementations
Clarification from David Kibbe
§ Are we dividing the proposals correctly?
§ CGC can do both!
§ Want to be able to get to the edge, but exchange structured data between HER, both complete and modular
§ More than one transport on the backbone
§ HISP has a single source
§ Latency of SMPT is a new thing to think about
§ Always going to have latency … as fast or as slow as the internet is based on where we are
§ Kick this back as a design assumption or user story issue
Comment from Steven Waldren
§ What is the intent?
§ This could be a user story issue
Comment from David Kibbe
§ Can SMTP deliver a structured Data File from server to server like REST?
§ People want to send messages & structured computable
§ Does this make a difference?
Comment from Vassil
§ Special SMTP
§ Packaging group is trying to determine the packaging format regardless of transport
o Is there one backbone protocol
o Does SMTP have to be a single protocol?
§ Edge protocol, there are certain requirements to meet with and we may have to provide reference implementation for more than one protocol
Comment from Dan Kazzaz
§ Single backbone and multiple protocols at the edge
Comment from Brett Peterson
§ Single backbone and multiple protocols at the edge
§ Focus on 2.x on Abstract Model for background
Comment from Lin Wan
§ What will be difference between NHIN Gateway?
§ Much will be dictated by security & trust
§ SMPT, IHE
Comment from David McCallie
§ SMTP model allows for a “freebee” at the end for POP of imap
Second part of discussion
§ How can we start to prove out both the core technical merits of various options and feel out applitite of community for picking this up (social & technical) really three main potential implementations:
o SMTP
o REST
o IHE
§ Call for champions & participants & drive towards the minimum threshold
§ Groups would run self driving and then at face-to-face to a heavy check in … see if any of them are establishing a critical mass … and also see if there are any we can eliminate
Comment from Vassil Peytchev
§ Understand how this will interact with the privacy & security group
Comment from Lin Wan
§ Time line and dependencies on other workgroups are disconcerning
§ Do we have a list of what we are trying to define?
§ Have the WG make a list of what they need this to do – committing development resources
Comment from Arien Malec
§ This is aggressive, but appropriately aggressive
Agreement: we will ultimately recommend a single concrete implementation for the pilot
(Sean) Propose plan and timeline for getting to recommendation
· Call for champions and participants to self-form groups creating three implementation proposals: SMTP, REST, IHE
· Groups work to create “minimum threshold” recommendations
· May 6 (in DC): group reports out status of all three groups, eliminates any not demonstrating critical mass
· If multiple options remain, two more weeks of development in groups
· May 18 (teleconference): final recommendation selected
· (ROUNDTABLE – overall plan)
· Decision: consensus on overall plan
· (ROUNDTABLE – call for champions)
· Action item: Brian will issue a call for champions via the discussion group, Arien will also post on the blog
(Brian) Flesh out “Minimum Threshold”
· Review wiki text
· (ROUNDTABLE – agreement?)
§ Are these the right three?
§ Are there more things we should add?
§ Call out to the WGs for additional things to add?
§ User experience … A minimal HER module
o Should this be a requirement for demonstration
o Minimal level of user experience
o Mapping User Stories to end product
§ Issue a call for IG later
§ Start with a blank page and say “form your own groups”
o SMTP: charged with creating “here is a picture of how NHIN Universe looks when the backbone is SMTP” and what are the preexisting bits?
o HIE
o REST
§ Brian will make a post to continue the “minimal threshold” conversation offline
§ All workgroup members are expected to comment on the thread
o Outside, next week on this call we will feel like we are close
o Everyone respond to a thread
§ Actions expected after meeting:
o Report to implementation group later in day, identify champions and call for broader participation
o Publish timeline to wiki
o Continue conversation about “minimum threshold” criteria on Wiki
o Agreeing on two points from last week:
§ 1) agreed to use working code and concrete pieces
§ 2) Single concrete implementation for the pilot (SMTP or another)
