RE: [ebxml-msg] Pull'ing a specific document

["Pim van der Eijk" <pvde@sonnenglanz.net>]

Hello Makesh,

 

We heard this requirement previously from German government users.

 

There is a feature called sub-channels (see section 2.5.4 of the Part 2) that almost does this. If the response message is expected on the MPC

 

http://receiver.example.com/mpc123

 

then a server could offer sub-channels like:

 

http://receiver.example.com/mpc123/?refToMessageId=messageid@sender.example.com

 

or with an XPath expression that matches SOAP headers. Right now such a convention (to use URL query syntax) is not standardized.  But it might be the easiest way to handle this.

 

The eb3:PullRequest has an open content model, so we could also invent some element syntax like

 

<eb3:PullRequest mpc="http://receiver.example.com/mpc123">

    <eb3:RefToMessageId>messageid@sender.example.com</eb3:RefToMessageId>

</eb3:PullRequest>

 

But this is a really an extension and again, is not standardized right now.

 

Pim

Subject: [ebxml-msg] Pull'ing a specific document

 Hi

 

In initial conversations with partners/customers over AS4, I have repeatedly heard the request to be able to Pull a particular document. The unique identifier could be based on the UserMessage that has been exchanged earlier e.g. PO # if a PO Message has been sent earlier.

 

Is there provision in the current spec to be able to support that ? My  understanding is that it is a generic Pull where the next available document is sent in the response.

 

Any advice please ?

 

Thanks

Makesh
