Subject: NRI link contract use case (was RE: [xdi] Agenda: XDI TC Telecon Thursday 1-2PM PT 2008-07-10)
Tatsuki, Sorry for the delay in replying to this -- I'm getting ready to go on vacation and trying to catch up with past mail. I think that the link contract pattern we discussed last week can work for an OP-defined contract per your requirements. We should make that an example use case we document on the wiki. I'd be happy to help work on this once I am back from sabbatical (six weeks).
