[ebxml-msg] RE: COnformance Clause

Title: RE: [ebxml-msg] Re: Use cases for messageOrdering

Hi all:

 

In order to prepare for the conformance agenda item (next conference call, next week)

here are the two candidate conformance clauses for MS 1.1 that are most favored by the IIC group (Options  2 and 3),
for your review. (Option 1 was "all or nothing" conformance.)

A conformance clause should normally be included in the final spec document.

 

IIC is actually recommending Option 2  ( 9 members preferred it, while 4 members preferred option 3)

As voters could also express - or not - second choices, we actually used a "weighted" vote that reflects more precisely

the total preference for each option (weight=3 for most preferred, 2 for second if any is mentioned, 1 for third if any mentioned).

Result is: 

33 (thirty three) for Option 2,

30 (thirty) for Option 3,

8 (eight) for Option 1.

 

I think this vote - starting with the design of the clause candidates - indicates how important

some features like Reliability and Ordering have been perceived.

You'll note that a special attention has been given to the interpretation of the keyword "optional" , as

this used to cause some trouble in past MS POC performances (see "definitions"). .

 

Note that  these clauses define conformance levels (rather than profiles),
based on implementation and usage investigation  (see the "rationale" section at the end)
These levels do not attempt to match functionally all possible profiles/agreements (CPP/A),
but should rather be considered as properties of the MSH implementation itself -
establishing a few broad classes of implementations (yet coherent from usage perspective),
so that the number of MSH certification options can be limited.

(A same conformance level roughly guarantees the same CPA playing field for all communicating parties,

supporting several usage profiles,  the detailed definition of which being done/enforced at CPP/A level.)
