Subject: RE: [ebxml-dev]: ebXML and limited resources

Hello Monica,

I think our story has been a pretty good one, although we haven't had the resources or really any managerial imperative to get our story out. Hence while I have heard of various things going on with NOIE and others here in Australia, we really haven't had time up until now to let these people know that not only is stuff in development in their own backyard, it is now in production.
I am currently doing a post implementation appraisal of our effort here and would be happy to engage with anybody who wants to talk about this work in detail. The email address below would be the most effective contact point. I will spawn a new thread here called "FRC B2B System - Victorian Gas Industry" although I'm not sure how much further users here will want me to take this issue.

I would encourage you to provide more information. Several ebXML
enthusiasts are working on the ebXML Joint Marketing Team to develop,
distribute, educate and entertain ebXML adoption stories to the
marketplace.  I have been working in that capacity, and have also been
working with NOIE and AWP to keep abreast of Australian efforts.  

I am on the JMT steering committee.

Finally, and technically, there is work within XCBF (Biometrics) under
OASIS to define a lightweight option for XML encoding using ASN.1.  It
does not have to have XML Encryption or Signature, and allows a great
deal of optimization for mobile or limited resource use.  For more
details, contact Phil Griffin at: phil.griffin@ASN-1.com.

I ook forward to hearing from you and getting more information.

Thank you.

Subject: FW: [ebxml-dev] ebXML and limited resources

Hello Daniel,

We have just gone live with an industry wide B2B implementation using
the ebXML messaging infrastructure, carrying an aseXML document as the
payload. aseXML is the Australian energy industries data description

I'm not sure what you mean by network resources, if you want high speed
network performance, clearly - dont use any form of web services, ebXML
or otherwise, don't use anything that uses HTTP as the transport layer.
If you are in an all Java environment use RMI (in conjunction with
RMIProxy http://www.rmiproxy.com/ if you have to cross firewalls -
otherwise it will fall back to HTTP anyway and defeat the purpose of the
technology). If you dont have the option of deploying on RMI then you
need CORBA and middleware. The difficulties of CORBA (and DCOM for that
matter) is kind of the problem that cumbersome web services are there to
fix. So - if ubiquity demands you sit on HTTP (or SMTP for that matter)
using an intermediate data description language (presumably some flavour
of XML) - expect overheads in the gateways and on the network.

ebXML is an excellent solution to many of the problems posed by inter
enterprise collaboration, certainly here in the Gas industry it has been
a startling success in the form in which we have used it ( ebMS v1.0
with signing and reliable messaging). However while it offers excellent
abstraction from the disparate platforms that are deployed by the
various participants, it is by no means 'lightweight' in the gateways.
The overheads in HTTPS, digital signing, reliable messaging, and so on,
are substantial, particularly if you need to scale up to large traffic
volumes. Our system (which has a hub and spoke architecture) has been
live for about 3 weeks and is currently doing about 100,000 messages
through the hub on a busy day. 

Given all the constraints we faced, I don't think any technology other
than ebXML could have delivered a viable messaging solution to this
industry; in conjunction with aseXML which has here demonstrated the
great strength of XML in providing a common data description language.

Subject: [ebxml-dev] ebXML and limited resources

Dear all,

We are currently dealing with XML based transaction standards used in
environments with limited network resources. Is there an investigation
available dealing with efficiency of ebXML under time or limited network
resource constraints?

Thanks in advance for comments,

Daniel Kilper
