Notes

Java Team Update

Beau Grantham

• Reported there were no significant developments on his work

Greg Meyer

• Commented on the agent side of the Java reference implementation
  • Currently working on the trust components
  • Developing Apache James bridge for the SMTP stack
    • This had been in development before the conversation about bounce issues
      • Adjustments will be made accordingly
    • Greg Meyer and Umesh Madan have been able to successfully pass messages back and forth
  • Also working on documentation through JavaDoc
    • Concentrating on configuration documents along with Beau Grantham
  • Finally, moving forward for LDAP store for certificates

Arien Malec

• Offer his assistance to Greg Meyer with respect to either API or configuration documentation

Greg Meyer

• Pointed WG towards [1]
  • This is a Maven site for:
    • Agent Gateways
    • Security and Trust Agent
  • This Maven site includes:
    • Guides and templates
    • A section on the documentation
• Asked whether this information on the Maven site should be migrated to the NHIN Direct Wiki
  • Further asked if a "Round the Room" was necessary

Arien Malec

• Deemed a "Round the Room" unnecessary
• Suggested the following approach moving forward:
  • Keep the class API library on the Maven site
  • Keep the agent on the NHIN Direct Wiki

Beau Grantham

• Asked for clarification on Greg Meyer's mention of "bounce" messages
  • Questioned if this had anything to do with conversation set for last week

Greg Meyer

• Clarified that his reference to "bounce" indeed had to do with the conversation last week
• Shared with the group that he had requested for a 30-day trial for a specific test software for the agent/gateway
  • Can move forward with the open-source one
  • Takes 30 days for the program
• Further asked what are the requirements for a Clover report
• Decided to take item off-line with Beau Grantham

Arien Malec

• Added that he would like to deep-link this into the wiki as well
  • Once complete, aims to link to the documentation page of NHIN Direct

Beau Grantham

• Continued that Vince Lewis has volunteered to work on the SMTP to XDR to XDM (XD* side)

Vince Lewis

• Added that he took a week sabbatical, but should start working on this again and aims for completion by tomorrow

Greg Meyer

• Further added that the Apache James custom matcher has been created

Beau Grantham

• Recognized that Pat Pyette has volunteered to develop the Web Config component
  • Wants to coordinate with the CSharp team to get their schema
  • Needs to get the SQL server script to the post-gress

Pat Pyette

• Affirmed Beau Grantham's note
  • Clarified that he has already accessed the CSharp team's schema

Vince Lewis

• Requested to discuss with Umesh Madan off-line about the storage components in the "HISP in a Box" model
  • The certificates are all pushed into one database

Umesh Madan

• Responded with the following storage components:
  • Certificate/anchor storage
  • Domain storage
  • Properties storage

Greg Meyer

• Commented that the Java reference implementation team has taken a more modular approach for storage
  • The database is enough configuration to get you started
  • The certificates may not be in the database
  • The HISP in a Box may just reference to an LDAP store

Umesh Madan

• Clarified the CSharp reference implementation's storage mechanisms
  • You could have a LDAP store
  • You could have a machine store
• Decided to take this off-line

CSharp Team Update

Arien Malec

• Passed the update report to Umesh Madan

Umesh Madan

• Provided an update of the CSharp reference implementation
  • The Configuration Web/Console UI component is going
    • It can provision CERTs
    • The team can watch the gateway dynamically change
  • MDN-Ack business needs to be resolved
• Items for this week:
  • Scripts and documentation
    • Asked where further documentation is required
  • More testing and unit testing

Sri Koka

• Asked where is the public gateway

Umesh Madan

• Asked Sri Koka to clarify what he meant
  • Umesh Madan is running a certain gateway

Sri Koka

• Asked if he can access the gateway

Umesh Madan

• Clarified that the gateway is the SMTP server
  • It is an internal server with SMTP and POP3
  • Decided to take item off-line

Claudio Sanchez

• Updated that the Config Web/ Console UI Component = 90% of bare-bones done
  • It should be able to tell you have everything you need to run a HISP
    • Includes set-up domains, certificates, trust anchors
  • However, should be able to provide a lot more information
    • Wants to create a "wizard-like" experience to creating domains, etc.
• Recognized that Arien Malec has mentioned the need for documentation
  • Asked how the CSharp team should coordinate the documentation

Umesh Madan

• Determined this should be discussed off-line

Chris Lomonico

• Added that the caching work for the CSharp reference implementation is essentially complete
  • Working around the asynchronous stuff
  • Wrapping up the final unit testing, should be done today

Vassil Peytchev

• Identified that not much progress was made last week on the XD* side of the reference implementation
  • Currently working on the incoming service and sending piece
  • Getting the XDR to XDM switch
• Plans to register some commits this week into the XD* side

Arien Malec

• Plans to build the documentation manually tonight
  • Almost got closed on documenting the common libraries until Umesh entered more code
  • Working on DNS among other things, hoping going to have this done tonight
• Stressed that "high quality documentation" is the key to making NHIN Direct accessible to HIT developers

Umesh Madan

• Thanked Arien Malec for essentially conducting a default code review through the thorough documentation

Setting Key Milestones

Arien Malec

• Asserted that they are nearing "feature-complete" on the CSharp side

Umesh Madan

• Agreed with Arien Malec
• However, identified some key outliers
  • Sean Nolan is working on the chain-builder side
  • Umesh Madan is working on the DNS responder

Arien Malec

• Further added that both the CSharp and Java teams have some progress to make
  • Both sides are working on the XDD side
    • Moving a little slower
    • Would like to shift some focus to the XD* arc
• Aims for a cross-project "feature-complete" state for the reference implementations
  • Target: Entering the Connect-a-thon
  • Asked the precise date of the Connect-a-thon

Brian Behlendorf

• Introduced his presence to the WG
• Responded that the dates are September 21st and 22nd
  • Will be collocated with the NHIN Connect Code-a-thon in Rochester, Minnesota
  • NHIN Connect are the true hosts for the event
  • Asked reference implementation WG members to Register for the September Code-a-thon

Arien Malec

• Aims to re-announce the September F2F Code-a-thon through a blog posting
• Discussed the goals for the WG's position by that point in time
  • Wants a beta-ready checklist
  • Key Goal: Get the 3-4 arcs done
    • SMTP/Gateway
    • Configuration
    • XDR Piece
    • XDM Piece
  • Aims for this to be completed going into the September F2F Code-a-thon

  • Recognized that if critical mass is not achieved for the Connect-a-thon, then they will look to early October
• Turned over to Brian Behlendorf

Brian Behlendorf

• Proposed opening NHIN Direct to other review outlets
  • Would like to get the code to a level of self-starting so that developers can plug-in

Umesh Madan

• Responded that ultimately timing is the question
  • Asked Brian Behlendorf if he was thinking about writing blog entries on Slashdot?
    • With a few key direct URLs

Brian Behlendorf

• Explained that he is trying to stoke some interest into NHIN Direct from developers
  • Tap into a sense of volunteerism
  • These folk will likely have little background in Health IT
    • However they may be interested in Health IT
    • Plenty of jobs coming up for HIT developers - might peak interest

    • Slashdot.org
    • O'Reilly Radar blog
    • Retweet action going

Umesh Madan

• Suggested waiting until the reference implementations are "feature-complete"

Arien Malec

• Suggested they would prefer an actionable hit list when they take such a step

Sri Koka

Umesh Madan

• Responded that Sri Koka is correct
  • However, by September it should be a lot easier to get plugged into the endeavor
