RE: [ebxml-msg] FW: Informal input to ebMS

Hi Doug,

 

Thanks for taking the time to look at the feedback.  Let me do some more digging on

your comments and get back to you tommorrow.

 

I thought you might have some thoughts on our latest discussion/issue.  Essentially

some implementations are returning an asynchronous ack before returning the

orginal http 204 response, and this is causing timing/resource issues.

In other words, I send you a message with no sync reply, I receive your Ack

asynchronously, then next I receive your http response synchronously.

 

Thanks for your time and interest,

mike dillon

Jeff and Mike,

I have a couple of questions on the consensus items:

• "cid based start parameter in the MIME Content-Type header" does not sound at all legal according to the MIME specifications.  The start MIME parameter accepts a content identifier as its value (the part of a cid URI after the colon), not a URI.
• "Payloads are not canonicalized during the digital signing process" seems to head away from interoperability.  If any intermediate makes a relatively small change (say, modifying the character set) to a payload, the recipient will be unable to validate the signature.  Canonicalization serves a number of useful purposes such as reducing the impact of inconsequential changes.  (And, in most cases, XML comments are not consequential.)

I much appreciated the sequence diagrams.  I'm reminded of one of the issues from the list because the diagrams once again point out an inability to request the business response and MSH acknowledgement in the same (asynchronous) message.  You can't create a derivative of (3b) putting the two "responses" together without combining them with a synchronous reply.

Your thoughts?

thanx,
    doug

Hi Jeff,

 I just sent this yesterday.  I will also send
 more formal feedback at the end of the tests....

Hi Ian,

 Attached is some input based on the current/past DGI ebMS interops.

 Also, attached are some examples of sequence diagrams we have been
 building, we would be willing to expand on these for inclusion
 in the spec or in some type of implementation guide...

 Can you forward me the concall number for the meetings Thursday,
 I'd like to dial in if that is ok with you.

 Thanks !

 Have fun in Miami !
