Hello
I am Antonio from Taiwan.
I have studied this subject - CPP/A negotiation for a while.
But,I am so confused and still don't know something:
 
1.In th CPP/A, what kind(type) of  content( element or attribute ) the two parties(Company A & B) need to negotiation?
   For example, we can negotiation the "price"  when we get the quotation from the seller.
   But I still don't see the Key point in the CPP/A.

MWS: At this stage of development, CPP/A is concerned only with information technology parameters and CPPA negotiation works only with the information technology parameters.  Negotiation on business information is a much more complex subject and we have not yet begun to address it.

 
2. I just know how to combine a CPA from 2 CPPs,and  I don't see the process of negotiation.
    This is strange to do this thing if we don't have the negotiation from CPP/A.

MWS:  The process of negotiation is described in the CPPA negotiation draft specification. Version .04, which you mention below, is still the current draft.  An update will be issued sometime in June.  Please feel free to ask specific questions on things you may not understand in the negotiation draft.

 
3.If CPP/A has it's negotiation algorithm, and then we can follow this rule to design the negotiation system.

MWS:  the negotiation protocol is described in the CPPA negotiation draft.  We are not attempting to define or standardize a specific negotiation algorithm.  As long as the rules in the negotiation draft are followed, it should be  possible for each party to use a private algorithm.

  
4.Can you suggest me to read some research papers or articles ,and it can help me to think the negotiation algorithm or
   understand CPP/A more?

MWS:  The best way to understand CPP/A is through the first few sections of the CPPA specification.  Negotiation and negotiation algorithms have been extensively studied for 100 years or more. There are many papers in the scientific literature.  Here are just a few:

G. E. Kersten. Modeling Distributive and Integrative Negotiations Review

and Revised Characterization, Group Decision and Negotiation 10(6), 493 - 514, 2001.

J. Nash, The Bargaining Problem, Econometrica 18, 155 - 162, 1950.

A Framework for Adaptive Interviewing, Proceedings of the 8th

International Conference on User Modeling, pp 105-116, Sonthofen, 2001.

    P.S.I have read the "Collaboration-Potocol Profile and Agreement Specification V 2.0" and
          "Automated Negotiation of Collaboration Potocol Agreement Specification V 0.04"
 
Thanks.
 
Best Regard.
