Agenda

1. Java Update
2. CSharp Update
3. Open Discussion

Java Update

Beau Grantham

• Reported on the Direct code-a-thon (at the NHIN Connect-a-thon)
  • Found very helpful
    • Was able to plug-in coders into the Java side
  • Walked through the Apache James' gateway and bridge
    • Created a Wiki page for the Java Agent Test Environment
      • Two James servers
      • Test that their system is working
• Mark Bamberg from NHIT is helping with the install piece
  • Passed it over to Mark Bamberg

Mark Bamberg

• Finished the Linux component of the install piece
  • Simple read-me from the Maven
  • Demand scripts built at the Code-a-thon
  • Beau Grantham will be reviewing it later

Arien Malec

• Suggested that Mark Bamberg also get it running on OS10 and Windows
  • It would be great to have all three for the installer

Mark Bamberg

• Responded that he has access to all three so it should be no problem

Beau Grantham

• Noted that Greg Meyer brought in the MDN piece
  • This was the last major piece missing from the agent side
• Stated that Pat Pyette has checked in the UI portion
  • Not yet fully-functional
  • Pat Pyette is not extremely familiar with that so he has someone else helping him out as his firm
• Recognized that ~30 unit tests have taken place for the service layer
• Added that Vince Lewis is addressing ATNA audit logging
  • This is primarily for the XD portion
  • Will eventually be brought elsewhere

Arien Malec

• Recognized that ATNA is just a specific format for audit logging
  • Need the ability to stream that to a remote location

Beau Grantham

• Added that they are using an Apache common to log-in

Arien Malec

• Responded that they should be able to screen audit events in that layer

Sri Koka

• Commented that they need to have both:
  • ATNA logging
  • External logging

Arien Malec

• Responded that they simply need an audit framework and the ability to place add-ins on top
  • Need to make sure they are not dependent on any specific format/type

Seonho Kim

• Commented that they probably need record repositories

Arien Malec

• Responded that seems a little bit like scope creep
  • Depends if someone wants to contribute that
  • Not sure if it is necessary, but welcomes the contribution

Chaminda Gunaratne

• Reminded the group of a number of change proposals
  • Sri Koka had asked about this

John Williams

• Introduced himself from Garden State Health Systems
• Asked for clarification about the change proposals

Sri Koka

• Responded that if they are using ATNA audit logs, then:
  • Need to keep in mind the ATNA syslog protocol
  • Requires the use of TLS

Arien Malec

• Asked that this conversation moved off-line

Beau Grantham

• Shared final point that they are re-factoring some of the XD code
  • Not tying people to what they have in the reference implementation
    • Bridge in a separate package
    • XD* permutations in a separate unit
      • Beau Grantham checked in some code
      • Aims to have done between today and tomorrow
    • They have two XD packages

Arien Malec

• Asked about Java's road to feature-complete

Beau Grantham

• Responded that the Java reference implementation is nearly feature-complete
  • Recognized that the Java team may have missed the mark on the LDAP section
    • Had a conversation with John Moehrke that led to this realization
  • Waiting on the completed install/set-up piece from Mark Bamberg
• Identified that their completion target may be pushed out a week or so

CSharp Update

Sean Nolan

• Reported that there was not too much action on the CSharp front
  • Shared that he had completed the certificate chain management work
• However, stated that he believes the CSharp reference implementation is in relatively good shape
  • Biggest gap for CSharp side: Web Config/UI Console piece
    • Waiting on Claudio Sanchez, who unfortunately has been stolen by his real work
  • Emphasized that a SMTP-based pilot would be still able to install and set-up a CSharp reference implementation

John Theisen

• Shared that he too has been distracted by his regular job
• Identified that he still managed to pushed his changes up from last week

Sean Nolan

• Decided to hold an off-line discussion on the hook for the logging
  • Allow others to pick and choose
• Suggested to start a discussion on the Wiki about what the API will look like

John Theisen

• Stated that the installer (64 bit) is fully functional
  • However this is excluding the Config portion
• Also shared that he put the "MSBuild" file in the repository (a BAT file)
  • Should simplify the coding process for those familiar with MSBuild

Chris Lomonico

• Had a couple of questions for Sean Nolan which he decided to take off-line
  • Would touch base that night

John Theisen

• Suggested going off-line for a discussion about his work as well

Arien Malec

• Addressed CSharp's road to feature-complete
  • SMTP side is feature complete
    • MDNs works
    • CERT chaining work is going up
  • XD* Side
    • No one has jumped into it yet
    • Shared that he has been working on a sideline XD* project
      • Takes XD metadata and brings it into XML
      • Happy to check that stuff in
      • Noted that it may be simple enough to translate to XDM, but not sure about XDD
    • Stated he would check that in today

Sri Koka

• Stated there are two ways to utilize the Java code for CSharp's XD* side
  • Tough to bring the XD* code from Java to the .NET side
• Questioned about the Codeplex materials as well

Arien Malec

• Suggested a strategy session for the XD* side for the CSharp reference implementation
• Asked Sean Nolan if he knew about the Codeplex materials which Sri Koka was referring to

Sean Nolan

• Responded that he was able to contact one of the original uploaders
  • That person was not familiar with the actual code/process, came from a while back

Sri Koka

• Added that it was from a company based out of India that developed those materials

Arien Malec

• Asked Beau Grantham for a clarification about the XD* piece on the Java side
  • Believed that it only addressed a portion of the process

Beau Grantham

• Responded that is the case indeed
  • It does the mapping and cross-tracking
  • It does not do what Arien Malec's sideline XD* project does

Arien Malec

• Asserted therefore that the two options can exist in parallel
  • Can take the Java code towards the .NET reference implementation
  • Can take Arien Malec's code toward the Java reference implementation
• Suggested a cross CSharp/Java call
  • Asked Jas Singh to coordinate this call

Jas Singh

• Responded that he would coordinate the call
• Asked for the best method to organize the call

Arien Malec

• Asked Jas Singh to e-mail the following:
  • Arien Malec
  • Beau Grantham
  • Vince Lewis
  • Sri Koka
  • George Cole
  • Ron Cordell

Summary

Arien Malec

• Highlighted the project timelines for the Implementation Geographies
  • A number of pilots want to begin "petal-to-the-metal" testing in November
  • Most pilots aim to "go live" by late December or early January
• Suggested target dates for Reference Implementation completion to match the pilots' expectations
  • Should be feature-complete by the end of this month (September)
  • Should be code-complete by the end of next month (October)
• Addressed the proposed Install-a-thon/Setup-a-thon
  • Noted that the end of October looks good for most
    • Suggested Wed. October 27th and Thur. October 28th
      • Recognized that one of the dates does not work for Beau Grantham

Beau Grantham

• Responded that he will try to make it, but has to check first

Arien Malec

• Noticed that neither Umesh Madan or Sean Nolan had responded as well

Sean Nolan

• Assured Arien Malec that either himself or Umesh Madan would be able to attend

Mark Bamberg

• Shared that he would not be able to make the 27th, but should be able to make the 28th

Arien Malec

• Shared final point that he would like to have the technical/integration partners of the pilots present during this proposed Install-a-thon/Setup-a-thon
  • Especially for the pilots aiming to start testing and installing in November

Round the Room

Open Discussion

Sean Nolan

• Thanked Beau Grantham for his help with respect to the Chain Builder on the certificate side
  • Plans to check that code in tonight

Beau Grantham

• Responded that he will be looking at that work to complete a similar piece on the Java
  • Waiting on Sean Nolan to check-in that piece

Arien Malec

• Recognized how there is essentially one overall reference implementation
  • One reference implementation team develops a piece, and then that "see-saws" over to the other reference implementation team
    • Has happened in both directions
  • Believes this is a good and healthy development
