Subject: RE: [ebxml-msg] A first assessment of ebMS profiling for AS2

Jacques noted a need for accomodating

3- Header fields: ebMS header mapping or profiling of AS2 headers & system identifiers (AS-From...)


Tim mentioned one approach:


For endpoint resolution (AS-To, AS-From, MessageId, etc), was thinking along the lines of what WS-Addressing provides, and honestly I'm not sure how ebMS 3.0 incorporates WS-Addressing




and so on could be HTTP entity headers as in AS2.  (But that is not in the spirit of WS-* in that message metadata foi them is to be scrunched into the message bodyparts in various ways. ebMS follows this pattern.)


I don’t think that WS-Addressing is relevant for AS4 identifiers, however. These party identifiers are logical identifiers of parties by values such as DUNS numbers that are used in the X12 EDI world, for example. Corresponding WS-Addressing values tend to be EPRs (or just URIs, er, IRIs).


If these Froms and Tos were mapped into what is available in ebMS 3, however, I would say that


AS4-To corresponds to the ebMS To field

AS4-To corresponds to the ebMS From field.


Service, Action, and Role correspond with no current metadata values in the EDIINT AS1 2 3 versions.


Message-ID  Need to consider what that is used for. RM functionality (like duplicate checking) or MDN/NRReceipt functionality.


Conversation-Id in ebMS has no corresponding value in EDIINT AS1,2,3.


AS4-Version etc. also will need some discussion.
