  2. Java Update
  3. Open Discussion


CSharp Update

Umesh Madan

  • Reported that the CSharp team has made some progress on connecting the DNS responder to the Configuration service

Chris Lomonico

  • Indicated that he is currently seventy-five percent complete with the Configuration service

Umesh Madan

  • Provided general update for CSharp team:
    • Arien Malec has been busy with XDS
    • John Theisen came up with a proposal for necessary namespace changes
      • Removal of NHIN references
    • Indicated that the CRL validation was completed last week
  • Shared that he has personally been focusing on HealthVault in order to test at the Code-a-thon
  • Passed on to the rest of the CSharp team

Arien Malec

  • Reported that not much has developed on the XD* side
  • Indicated that a general strategy has been developed
  • Stated that he is currently mapping the high-level metadata object model to Vassil Peytchev's metadata model
  • Asked if either Vassil Peytchev or George Cole had any updates

Vassil Peytchev

  • Responded that he has no update to share
    • Will see what he can do moving forward

Arien Malec

  • Asked John Theisen to speak about the namespace changes

John Theisen

  • Indicated that his proposal is a strategy to remove NHIN from the various spaces
    • New namespace = help.direct.(component)
      • Most people can get around that
    • Settled on have the assembly names follow from the namespace
      • Basic stuff there
  • Stated that they have prioritized other work to after completing these initial steps
    • Ex: Moving some of the code around
  • Therefore suggested a code-freeze this Thursday to Friday to prevent any collisions
    • Rationale: have this completed prior to next week's Code-a-thon

Arien Malec

  • Indicated that this has not been discussed on the Java side
    • Suggested the Java team consider a namespace change as well


Java Update

Arien Malec

  • Recognized that Beau Grantham is not on the call
  • Asked Greg Meyer provide the Java update

Greg Meyer

  • Indicated that Beau Grantham had sent out an update
    • Configuration Side
      • Filled out 70%-80% of the stubs
      • Trying to finish the addressing service and pull into the UI
      • The code for this was checked in yesterday (validated by team)
      • Goal is to get a centralized configuration in the long-term
    • XD Side
      • Passed over to Vince Lewis

Vince Lewis

  • Reported that he is in the process of adding the audit piece (ATNA)
    • To write to a file
    • Pull out a VSB
  • Added that he is working on the optimal configuration piece for the XD* side
    • Should be up today

Arien Malec

  • Commented that he has been measuring the number of lines of code that have been uploaded on each side
    • The Java team has been incredibly productive of recent
    • The Java team is pretty close to having a "unit test to lines of code" ratio of 1
      • A ratio of 1 is the general best practice for coding
      • Indicates that the code the Java team is checking in is also of quality

Greg Meyer

  • Asked Pat Pyette to provide an update for the UI Console

Pat Pyette

  • Reported there was nothing to add for the UI (for the client)
    • Shared that he has personally been really busy
    • Wants to get this going soon

Greg Meyer

  • Added that he has been cleaning up the Java build where possible
    • Found the root cause for many issues with the Java build
    • Five or six independent machines working fine now
  • Recognized that Mark Bamberg was not on the call
    • No new recent commits towards the installer
    • The install scripts will be worked on through this week
  • Further recognized that Michael Firriolo has been doing great work on the Java testing
    • Michael Firriolo has been offering suggestions for documentation where it is lacking
  • Commented that the Java team in general is moving forward
    • The Java team checked in a lot of code last week

Arien Malec

  • Asked Pat Pyette if the Java team was considering a similar namespace change

Pat Pyette

  • Responded not at this time
  • Added that the Configuration is mostly complete aside "settings" related issues

Greg Meyer

  • Added that he had to make a quick change to the Java code (not checked in yet)
    • Found another conflict around a couple of annotations regarding Java 6
  • Suggested holding an off-line discussion around some of the documentation for the Config
    • Suggested parties: Tim Houlding, Pat Pyette and Greg Meyer


Open Discussion

Approach for October Code-a-thon/Installathon
Arien Malec

  • Stated he would like to discuss what they WG wants to accomplish next week
  • Highlighted an exercise completed at the CONNECT Code-a-thon
    • Completed a walk-through of the development of the Java Configuration
  • Suggested conducting a similar exercise at this Code-a-thon for a HISP
    • Requires everyone to come in with their own domain
      • Everyone sets up their domains
      • Then they get parallel configurations of those domains
        • Goal: achieving interoperability
    • Suggested this as the organization model for next week
      • To the extent that they have an exercise for getting a HISP up-and-running
  • Solicited input from Greg Meyer and Umesh Madan as development team leads first

Greg Meyer

  • Asked if these are going to be public domains or in the internal network

Arien Malec

  • Responded that he initially thought public domains
    • Could only do in-network if too much of a problem

Greg Meyer

  • Asked if public domains can do certificate resolution
    • Commented that a number of them use GoDaddy to host their domains

Arien Malec

  • Recognized that GoDaddy does not allow NS records to be pointed
    • GoDaddy does not allow other components to be hosted by someone else
  • Recognized that DNS does work with public domains
    • Suggested looking at the domain hosting services that allow you to actually do that
  • Highlighted the Best Practices WG document for Certificates
    • The document suggests using a special purposes domain
      • Point all of that over to whoever is managing the certificate
  • Stated these are exactly the types of things we should blow through prior to and during the Code-a-thon
    • Key lessons that need to be learned early
    • Can then publish an "operational best practices"

Umesh Madan

  • Suggested they can also use a "dummy" domain as well
    • HealthVault is doing something similar
    • Used GoDaddy to point NS records to his DNS box
      • Thats the extent to which he would use GoDaddy

Greg Meyer

  • Commented that a step through will be very useful

Arien Malec

  • Asked Umesh Madan to further clarify

Umesh Madan

  • Responded that he created two domains
    • HSDincubator.com
      • Two NS files
        • Intro file hosted in GoDaddy
        • The files in GoDaddy are pointed to his main domain through .info
      • Still need a place to host an address record
    • HSDincubator.info

Arien Malec

  • Exactly the type of records they need to keep track of these

Greg Meyer

  • Asked if someone could write up what Umesh Madan just shared

Umesh Madan

  • Stated that he would try to get this written up by Thursday morning
  • Nice thing is that it won't take to long to get this up and running
    • TLLs take 30 minutes

Greg Meyer

  • Turned to a different point
    • He may look for some documentation for tiny-DNS
  • Asked if Brian Behlendorf was on the call
    • Recognized that Brian Behlendorf was not on the call
    • Commented that he had asked him for some of the aforesaid documentation

Umesh Madan

  • Commented that using BIND could be as well simple
    • Just has to write out somethings manually

Greg Meyer

  • Responded that tiny-DNS may actually be simpler than BIND-9

Umesh Madan

  • Agreed that in the long-term that makes sense

Greg Meyer

  • Asked if they are going to have a public certificate authority exchange
    • Will there be a repository for public certificates?

Arien Malec

  • Responded that is a great idea
  • Recognized that Brett Peterson is not on the call
    • Suggested that maybe VisionShare can be one of the Certificate Authorities (CAs)
    • Suggested that one of them can also be one as an SSL

Greg Meyer

  • Commented that he is trying to use as many public CAs as possible
    • Pushing them to the Java code repository
    • Might be useful for people to choose there

Umesh Madan

  • Added that Greg Meyer could create a folder to store certificates through Mercurial

Arien Malec

  • Responded that it is a sound idea

Greg Meyer

  • Indicated that is possible

Umesh Madan

  • Commented he could set it up under NHIN-D
    • Could also put CERTs and anchors there

Greg Meyer

  • Responded it is not a bad idea to put public certificates in such a folder for the Code-a-thon
    • Could also use for testing in general

Umesh Madan

  • Stated that he is automating some of the exchanging information long-term

Arien Malec

  • Indicated there has been a common question
    • "I have my existing exchange infrastructure..."
    • "How do we bridge this to the Direct Project?"

Umesh Madan

  • Responded they can definitely do that
  • Believed the answer should be easy
    • Run it as a gateway
    • Do not virtually have to do anything

Arien Malec

  • Responded that many also state that their exchange infrastructure is hardened
    • "Can I still connect to Direct?"

Umesh Madan

  • Indicated that they look quite similar
    • Could basically hook yourself
    • Pass the rest to the NHIN-D agent
  • Stated that he may need to look at the actual infrastructure
    • Will not be able to look before the Code-a-thon/Install-a-thon
    • Suggested that someone try writing a hook themselves
      • It is DLL so you can load it

Greg Meyer

  • Java side has a book covering some of the materials
    • Said book could also cover such a topic

Arien Malec

  • Shared that this particular question is coming from the VA

Umesh Madan

  • Commented that they are formed in terms of gateways
    • Their internal boxes are not looking to the outside world
  • Indicated it is something worth exploring at the Code-a-thon if some prior work is completed


Round on Proposed Approach for Code-a-thon
Arien Malec

  • Suggested that they continue with a round on his suggested approach for the Code-a-thon
    • Approach
      • Developers come with a registered domain
        • Would like to use public domains
      • Go through the exercise of configuring a HISP that can serve that domain
      • Understanding the process of developing interoperable systems
    • Reference Implementation WG
      • Can you help others do that?
      • Or work as an implementer?
