[ebxml-cppa-negot] NDD Schema and Sample NDD instance document

["Kartha, Neelakantan" <N_Kartha@stercomm.com>]

Here is the promised NDD schema and a sample NDD instance document that
conforms to this schema. The NDD
instance document contains the first 15 or so elements in the spreadsheet
that we filled earlier this year. The elements
that are represented are different enough in their negotiability
characteristics, so that the NDD schema captures all
of the negotiation patterns I had identified earlier (in the document titled
"Patterns in the negotiability of elements" that
I had posted to the list in June 2002.)

I have added comments on the NDD schema and instance document in the hopes
that people will read them. Please
send comments to me and to the list. 

The NDD schema is based on a skeleton schema that Dale Moberg had sent to
me---however, note that I have made several changes and additions.

What remains to be done:

1. Flesh out the NDD instance document more. Doing this might require
additions/changes to the schema. However, in many (most?) cases,  what is
already in the schema should suffice.

2. Discuss whether the approach proposed here is appropriate/good enough.



I noticed one issue while doing this work. There are some elements (such as
Start/End etc.) that are present only in the CPA. Assuming that one starts
out with two CPPs, the two initial NDDs point to these two CPPs. The
question then is : how is the negotiation of these elements, present only in
the CPA, to be done, since the NDD does not contain any references to them?
An approach is: first finish the negotiation of the CPPs, form a preliminary
CPA, with some arbitrary values for these elements. Then form two NDDs for
this CPA, focusing on elements that are present  only in the CPA. 

Comments?

Best regards,

Kartha
