  • Pointed the WG to Brett Peterson's post:
    • [2]

Brian Behlendorf

• Reviewed logistics for CollabNet
  • Good WiFi
  • LAN connection available
    • Bring Ethernet cables
    • If most want LAN connection, a switch can be arranged

C-Sharp Update

Umesh Madan

• Reported a moderately busy week on the CSharp side
  • Began holding stand-up calls every other day again
• Indicated that Arien Malec sent notes from the CSharp XD* meeting from Monday
  • CSharp XD* and Client API Architecture and Plan
• Stated that Chris Lomonico has been working on the DNS portion

Chris Lomonico

• Responded that the cache code is in there now
  • Performing test cases on some of the stuff

Umesh Madan

• Further indicated that these days he has been more busy
  • Completed intermediary resolution
  • Looking at the CRL revocation stuff
    • Lack of libraries at the native level
    • May not want to do that, will have to assess

Arien Malec

• Reported that they held a meeting yesterday on the C-Sharp XD* plan
  • Discovered they needed a strategy to bring it all together
  • Had created an object model at a higher level
    • Mapping of it to the XML
    • Developed from the EHR vendor perspective
  • Vassil Peytchev has developed a similar object model, but utilized XML serialization
    • Arien Malec realized it would be easy to translate his code over to Vassil's work
      • Arien Malec will map his object model to Vassil Peytchev's XML serialization ebRIM object model
      • Useful to read/write over the object model
    • Noted that Vassil Peytchev has a little bit of work remaining on his object model
  • George Cole has his own code which can serve as an interface
• Requested that Umesh Madan review the overall plan:
  • CSharp XD* and Client API Architecture and Plan

Umesh Madan

• Indicated that the next couple days he will be off-site
  • Should be able to take a look at it come Thursday or Friday

Arien Malec

• Responded that is okay and that the code will be more complete by then
• Described the key components to the CSharp XD* Architecture
  • Arien Malec - Client API
  • Vassil Peytchev - XDR/Serialization
  • George Cole - XDR/SOAP side
• Identified remaining work: Writing the package and send components for XDM + SMTP
  • Noted that .NET does not have the libraries for the zipping files
  • Possible suggestion: [3]

John Theisen

• Expressed willingness to help Arien Malec off-line with that

Vassil Peytchev

• Recommended they look at .NET's J Sharp libary

Arien Malec

• Indicated that once they get through the first three pieces, then the fourth piece should not be too tough
  • Plans to make progress by Wednesday on the code

Vassil Peytchev

• Stated he believes this should work

Arien Malec

• Stated that CSharp is in good shape to meet their objectives

Brian Behlendorf

• Asked if the XD work would be done by the Code-a-thon/Install-a-thon

Arien Malec

• Responded that they should be in testing by the Code-a-thon/Install-a-thon

George Cole

• Indicated that he has to finish his piece by Friday night
  • After that, he will not be able to work on it until October 25th
    • Right before the Code-a-thon/Install-a-thon

Brian Behlendorf

• Stated desire to encourage developers aiming to use .NET to come to the Code-a-thon/Install-a-thon

Umesh Madan

• Responded that they should say that anyways
• Stated that all the major features are essentially set in place
  • Umesh is still working on the CRL caches

Brian Behlendorf

• Suggested once more having a list of "nice to have, but not critical" items which people can work on during the Code-a-thon

Umesh Madan

• Indicated it his goal to come to the Code-a-thon/Install-a-thon with the HealthVault

John Theisen

• Reported that he was able to make the last pieces of the installer functional
  • Still some minor technical issues linger
  • Need to fix the permission issue so that the Config can write out

Chris Lomonico

• Reported making progress on the work he adopted and willing to move forward

Java Update

Beau Grantham

• Indicated that his time has been limited since last Thursday
• Reported on the abstract metadata object model which he worked on
  • Has ability to the translate into the XML serialization
  • First draft has been dropped into the base-line
  • Trying to avoid XD* coding overlap
• Highlighted that Greg Meyer has done some great documentation for the agent
  • So that developers can use the agent without the gateway

Greg Meyer

• Reported assembling a guide for developers:
  • Focused on the agent separate from the gateway
    • Code examples
    • Transformations examples
  • Encouraged Direct Project participants to add to it

Beau Grantham

• Added that was spun mostly from developers who expressed interest in the Java implementation
• Asked Greg Meyer about his addition to the Config piece

Greg Meyer

• Indicated that he has been helping Pat Pyette with this
  • Hooking all of that into the gateway
  • Only configurable by XML
  • Hopes to have it setup in the next couple days

Beau Grantham

• Asked if Greg Meyer would essentially make it a basic module

Greg Meyer

• Responded that is an alternate way to create it
  • Unlike the C-Sharp, will not make everything go through the configuration service to get certificates and anchors

Umesh Madan

• Responded that Greg Meyer's statement does not accurately paint the CSharp approach
  • Anchors do not need to be pulled from the agent
  • The intent was to make the reference implementations match
• Expressed view that regardless, the aforesaid approach will add a greater functionality to the Java side

Greg Meyer

• Reported that he incorporated an Adobe database
  • Can still be changed variably
  • Adding to the Configuration service

Umesh Madan

• Commented that it is a good idea to have a memory store for testing

Beau Grantham

• Asked Tim Jeffcoat and Pat Pyette for updates with regards to the Config piece

Tim Jeffcoat

• Reported making progress on the UI portion

Pat Pyette

• Indicate he worked with Arien Malec to pull together some work

Beau Grantham

  • He has been planning to create a proposal regarding audits
• Noted that packages are applicable to the client side as well

Beau Grantham

• Indicated that he will follow-up with Vince Lewis
• Asked Mark Bamberg about the install scripts

Mark Bamberg

• Plans to commit code-complete install scripts by the end of the week
  • For the agent and gateway
  • Also a graphical installer

Beau Grantham

• Indicated that his plan is to utilize the model for the remaining pieces

Arien Malec

• Asked Java about their progress towards the following goals:
  • Feature-Complete: End of this week
  • Production-Ready: End of month

Beau Grantham

• Responded that he still believes they are on track for mostly feature-complete by the end of this week
  • Mostly code-complete by the end of the momth

Open Discussion

Brian Behlendorf
 

• Suggested reaching to people who are interested in getting involved
  • Recognized that such a public push was considered beforehand, but has been left on the back-burner
  • Suggested reaching out to places like the O'Reilly Radar to draw in new developers
    • Maybe Andy Oram can post it
    • If you have these skills and want to get into Health IT
    • Come the first day of the Code-a-thon
  • Posted possible message for review:
    • [4]
• Highlighted the extra Wednesday morning session
  • Deliberately decided to start at noon PDT on Wednesday to allow those traveling sufficient time
  • However, Brian Behlendorf recognized two potential uses for early Wednesday Meeting
    • Vassil + crew are arriving early to get a head start
    • On-boarding for those not familiar with Direct Project

Arien Malec

• Stated that it can be a good idea to do a "cold" walk through of the code and specifications
  • Forces the Direct Team to really understand what they are assembling by having to teach others
  • Suggested working with communications WG
• Recognized that if it takes the group away from the core task, then it is not useful
