Java Team Update

Beau Grantham

• Reported that the XDD side is getting near production ready
  • Apache James would pick it up and forward it to XDS to XDR
  • Could be transformed to an XDM zip file as well
  • Passed through the security agent
• Shared that he has put up a list up on the wiki

Arien Malec

• Asked: Vince is working on the transform agent?
• Commented on the XDM component
  • Noted that some hard-coded work is in there
  • Transform is done
• Believed that the front-end of the reference implementation needed work

Vince Lewis

• Identified that the XDD Spec was worked on during a meeting last Friday
• Asked what the next step is for XDD
  • Should they be changing everything or leaving XDR?

Arien Malec

• Stated that XDD is XDR with non compliant metadata

Vince Lewis

• Asked if they should leave both XDR and XDD in there

Arien Malec

• Responded that Vince Lewis does not have to remove anything
  • He can run the same code with SOAP headers and be XDD compliant

Vince Lewis

• Commented there is some stuff, however, that they want to remove/add
  • Asked again: Do we want to bring down to XDD, or do we leave extra routing to XDR?

Arien Malec

• Responded that extra headers are not going to mess anything up

Vince Lewis

• Understood where Arien Malec was coming from

Beau Grantham

• Commented that the gateway now enables
  • Multiple documents
  • Multiple recipients
• Stated that Javadoc process coming along really well
  • Private documentation being worked
  • Javadoc coverage has been pushed up to the API
• Added that Pat Pyette has checked in some code with respect to the config

Pat Pyette

• Commented that he is working on the last piece for the UI
  • Trying to hook up the UI to the top layer
  • Once it works, then it should be pretty simple to replicate
• Aims to check something in today
  • Parts of it should work end-to-end

Beau Grantham

• Addressed the agent side
  • Remembered that Arien Malec asked someone to take on the agent piece while Greg Meyer is on vacation
    • Beau Grantham has agreed to start working on it
    • Works with a CRL file
    • Successfully sends a message
• Reminded the WG that he will be out from the end of the week through the weekend
  • However, he will be flying to the code-a-thon next week
• Compiled a hit-list for the Java reference implementation
  • Road to code complete

Arien Malec

• Asked: Are we on track for an end-of-month?

Beau Grantham

• Responded that he still thinks it is possible

Greg Meyer

• Added that he aims to get the MDN stuff offline

Arien Malec

• Asked about the outstanding agent issues
  • Certificate chaining
  • MDN stuff

Umesh Madan

• Asked Beau Grantham to work with Sean Nolan on the chaining issues

CSharp Team Update

Umesh Madan

• Addressed last week's focus
  • Documentation
    • Someone should be able to run with them
    • Be able to build the gateway and the config service
    • Built ability to export CERTs
  • Setup Scripts
• Highlighted what he specifically worked on last week:
  • Public gateway is up and running
  • DNS Responder
    • For back-end CERT storer
    • Service should be scalable
    • Once this is done, Umesh Madan will be off line
  • Added remaining items to the Open Questions list on the CSharp Team Page
    • Auditing - John Theisen
    • CERT Resolver
    • Caching
    • Chain-builder

  • Need more code coverage
  • Not yet at the level of the Java side

John Theisen

• Added that he made some progress since last time
• Stated that he is also working on the container issue

Umesh Madan

• Asked: Can the auditing system be built on top?

John Theisen

• Responded yes
  • Factory style returning of information
  • Trying to make sure it is easy for different companies to incorporate the libraries they chose

Arien Malec

• Asked if John Theisen could write up some notes on this
  • Essentially a developers guide

John Theisen

• Agreed to do it for the logger's library
• Added that is working on a "poor man's container"
  • No dependency on a third party container
  • Keep the code base lightweight
  • Still have the option for others to use different containers

Umesh Madan

• Added that he will make sure to look over the proposals

John Theisen

  • TTL tester to make sure the cache doesn't expire
• Added that he will take on any other items the team needs addressed

Umesh Madan

• Direct to Chris Lomonico: Since you have already worked on the cache, if you could take on the improvements for the CERT Resolver

• Stated: that would be fantastic!

Chris Lomonico

• Agreed to take the CERT Resolver improvements on

Sri Koka

• Added that he is conducting the unit tests
• Asked: Do you have the data/records for us, or should we start from scrap?
  • Further asked: How did you do it?
• Stated that he will contact Chris Lomonico after the Reference Implementation WG call
• Asked: Do you have a preference?
  • MX and CERT

Arien Malec
