[ebxml-cppa] Comments about Negotiation White Paper

[Yukinori Saito <y-saito@ecom.jp>]

Followings are comments about Negotiation White Paper.

1. Questions
(1) I don't clearly understand the role of UDDI and ebXML Registry, and
differences of functions between UDDI and ebXML Registry. Both UDDI and
ebXML Registry are services or schemas about discovery of companies or
services. In the view point of negotiation of CPA, please tell me typical
roles or functions of both UDDI and ebXML registry.

2. Comments
(1) If I understand correctly, NCPA means 'Negotiation CPA'.
There is a statement such as 'Normal CPA' in Section 3.6 (Basic Components).
I think this 'Normal CPA'   is mistaken. This should be altered to
'Negotiation CPA'.

3. Requirement
(1) If some full line examples are prepared, It will be very helpful to
understand functions and structures of Negotiation.
If two cases (manual negotiation and automated negotiation) are provided,
that will be much better.
-NCPA
-Manual Negotiation ( if capable)
 2 CPPs, initial CPA, manually negotiated CPA
-Automated Negotiation
 2 CPPs, 2NCPPs, initial CPA, automated CPA

(2) It is difficult to understand architecture of Automated Negotiation,
because this white paper is described by texts only.
I recommend to insert some graphical overview about architecture of
Automated Negotiation.
I made a draft about the architecture of Automated Negotiation, named
'Overview of Automated Negotiation Architecture'.
Please review this draft. If you notice some misunderstanding parts, please
indicate them.
If you think it is suitable to insert this draft to the Negotiation White
Paper,
please insert this document to the White Paper.

Best Regards,
Yukinori Saito
