Attendees: Neelakantan Kartha, Dale Moberg, Marty Sachs, Jean Zheng.

Discussion: There was discussion of the NDD document that Kartha posted. The consensus was that most of the elements or attributes in the CPP were negotiable, whether or not they were explicitly identified as being negotiable in the specification. It was agreed that we need to discuss each element in the CPP with regard to its negotiability, the type of negotiation possible for the element, and additional information involved in the negotiation (such as the numeric ranges, step size etc.). Kartha volunteered to come up with a first cut, one page enumeration of some of the key elements in the CPP that are negotiable, to get the discussion started. Dale volunteered to do the investigation of negotiability for the security related stuff (such as certificates etc.)

There was a brief discussion of negotiation of packaging details. Dale commented that the optional mime/body part (such as the attachment of a CAD drawing that goes with a purchase order) should be negotiable. Dale also brought up the issue of whether extensions to the CPA are negotiable. His opinion was that this could be postponed for now, and the others concurred.

Jean commented on her interactions with Brian. She said that Brian agreed with the distinction between a CPA proposal (the very first message in a negotiation, which sets up the context, NDDs etc) and CPA offers (the other messages in the negotiation). She also raised the following issue: Suppose party A sends a negotiation proposal to party B with a timeout of T seconds and T seconds has already passed. What should be done at A at this stage? It was agreed, after discussion, that sending a message to B, with the information that a timeout has happened and then terminating the thread at A is a reasonable thing to do. The motivation for sending the message to B that timeout has occurred is because a human might be monitoring at B, and this message would be useful to the human.

Respectfully submitted,
