Notes

Vince Lewis

• Informed group that he is conducting clean-up as well as re-factoring
  • Should be done by the middle of next week

Arien Malec

• Recognized that Beau is working on the object model
• Asked if Beau Grantham had checked in the resolver

Vince Lewis

• Responded that Beau Grantham has prepared a sub-resolver and interface

Arien Malec

• Indicated that is a good way to do it thus far

Vince Lewis

• Suggested they iron out the business logic to the resolver

Arien Malec

• Indicated it would be based on a configuration where you always know the domain
  • With respect to sending the XDR
  • Otherwise you send the SMTP

Vince Lewis

• Asked about the idea that resolver is supposed to determine the endpoint
  • Not just determining addresses

Arien Malec

• Expressed agreement with Vince Lewis' understanding
• Spoke of a hand-written implementation
  • Suggested looking at the MedAllies implementation

Vince Lewis

• Agreed with Arien Malec's perspective

Arien Malec

• Indicated that over time they can swap it out to UDDI without changing anything

Vince Lewis

• Expressed goal to not create something too cumbersome
  • If he is sending SMTP, then he needs to send to that endpoint
  • However, if kept simple then there should be no problems

Arien Malec

• Transitioned to the CSharp side

Vassil Peytchev

• Clarified that he has been out of the loop for a little while now
• Indicated he had been pulling together an object model for the XD* metadata
  • Generating XD metadata when there is a CDA payload
    • Plans to merge this
• Recognized that Arien Malec has created a similarly functional XD* object model
  • Generated without SOAP
  • Once he merges his item into the repository
• Determined to hold a call with Arien Malec to determine which direction to go
• Stated that they will be pulling from the codeplex
  • Not sure if anyone worked on that since the Code-a-thon

Arien Malec

• Responded that no one has worked on it since Ron Cordell put that in
• Clarified that George Cole will be provided some code in smaller packages
  • Recognized there may be two competing object models

George Cole

• Stated that a single project was checked-in which should address some of the XDS
  • Registry error
  • Registry error list

Vassil Peytchev

• Asked if this was an XD or XDS file (unresolved)

Arien Malec

• Clarified that he does not have a sense of ownership
  • At the end of the day, if they can get an implementation up - that would be preferrable
    • Document entries - registry package mission sets
• Suggested they decide between Vassil Peytchev's and Arien Malec's approach
  • Need to determine the correct path to go down before hooking up to the web configuration
  • Not sure that they need all the XD dependencies

Vassil Peytchev

• Agreed with Arien Malec that not all the dependencies are important
  • If they can get the web service to generate the object graph through parsing
    • Then they can move forward

Sri Koka

• Indicated that he was not able to do as much
• Stated that he had looked at Arien Malec's code
  • Asked Arien Malec if he used LINQ

Arien Malec

• Responded yes

Sri Koka

• Indicated that he does not want to do this from the front

Arien Malec

• Recognized that they have a couple of decisions to make
• Asked Vassil Peytchev if he was free for Monday

Vassil Peytchev

• Responded that he would be free after 11:00am EDT

Arien Malec

• Decided to hold a CSharp XD* architecture meeting
  • Invited Vassil Peytchev, George Cole, Sri Koka and Jas Singh
• Indicated that by Monday his object model should be able to "round-trip"
  • Is XDR code more compatible or is the parsing option preferred?
