Subject: [ebxml-msg-comment] Public Comment
Thanks for the opportunity to comment. Sorry this is late. My comments on the ebXML ms 3.0 spec are as follows. Section 2.2 MEPs This section is useful but the problem is how far to go. The document mentions the use of eb:RefToMessageId but not conversationId and does not talk about the relation in time between the various messages. So I am not sure what role this section plays in a document on the messaging standard. I suspect that ebBP or some such would be a better place to talk of these things in terms of the structure of transaction patterns? Section 3 - Message Pulling If the challenges can be met then I see this as a great step forward for ebXML ms3.0. In our current communities we have been moving to ebXML ms2.0 from a mechanism based on XML posted over http with responses being polled by the client. The moment we explain that we are moving to push push many of our partners respond with "it wont work". Our intention would not be to move to an exclusive push pull model but rather when outbound messages fail to be received we would take those messages and requeue them such that they could be pulled by a partner as part of their recovery process. Section 4 - Processing Modes I think this concept is a very good one. Not sure why the default P-Mode has no reliability. My view of ebXML ms is that a key feature is reliable messaging. Conformance Profiles Having choices is good however we are in a very diverse community (using ebMS solutions from three different vendors in the community plus an open source implementation and Three home grown ones). When it came to interop even our use of ebXML CPA/CPP threw some of them. It would be useful to try and come of the fence here even if it is to make a stand on the default first port of choice for all the commercial vendors. Thanks for all the hard work on this standard Derrick Evans BT OneIT
