Hi
Did any body has work on the RNIF .I have some problem in working with
it.....
If any body has work on this please let know...
Thanks

Thanks all for your kind responses

I have some more questions - specially regarding the reliable messaging
capabilities of RNIF 2.0.
In several answers I have got (both online and offline) I'm told that RNIF
does NOT provide reliable messaging.

On the other hand, in a paper (from WebMethods) comparing RNIF 1.1 and RNIF
2.0 I have read that:

"RNIF specifies a reliable messaging mechanism based on Acknowledgements and
supplies a set of standard choreography models that all PIPs must follow."

 <<RNIF 1.1 - 2.0.pdf>>
By reading the answers, the above paper and also the RNIF 2.0 spec - and I'm
now a bit confused.

Is it true that RNIF 2.0 only provide a reliable messaging mechanism when
you also use the different RosettaNet PIP's? I.e RNIF 2.0 can not be
considered as a "standalone" Message Service Handler (MSH) in the same way
as ebMS? And that the reliable messaging mechanism in RosettaNet is achieved
by sending "Receipt Acknowledgment" messages/documents from the "application
layer" by executing the RosettaNet PIP's?

Also I understand that the future RNIF 3.0 will be layered on top of ebMS.
Or even that RNIF 3.0 == ebMS?
Is it true that ebMS will be used INSTEAD of RNIF (3.0) or what capabilities
do you believe that RNIF 3.0 will put on top of ebMS?

When do you believe that this new RNIF 3.0 spec will be available?

My best regards

        Hi,
        we have an internal discussion regarding ebMS vs. RNIF.

        If we are not using the RosettaNet PIP's (processes and documents) -
is it best to use ebMS or RNIF as wire protocol?

        <arvola>

        RosettaNet is a vertical standard focusing on the needs of the
Information Technology, Electronic Components, and Semi conductor
Manufacturing industries, whereas ebMS is intended as a horizontal standard.
If you are not using RosettaNet PIPs, it is preferrable to use ebMS as the
wire protocol because:

        1. It is compatible with SOAP.

        2. It offers reliable messaging capabilities.

        3. It supports XML Digital Signature which is more flexible compared
with S/MIME (supported in RNIF) in terms of allowing referenced objects (not
necessarily part of the physical message payload) to be signed.

        4. It may have wider interoperability with third-party B2B
implementations.

        </arvola>

        What are the pros & cons of using ebMS (2.0) vs. RNIF (2.0)?

        <arvola>

        If you want to use SMTP as the transport protocol, then you will
probably need payload encryption. This is directly supported in RNIF 2.0
using S/MIME.

        Payload encryption is not specified in ebMS 2.0. TIBCO's ebXML
offerring does support payload encryption. However, this is not guaranteed
to inter-operate with ebXML software offerings from third parties.

        TIBCO's RNIF 2.0 implementation has been available since the summer
of 2001. It is a more mature product compared with TIBCO's ebXML offering.

        </arvola>

        Does anyone have or are aware of any document comparing ebMS (ebXML
Messaging Service) and RNIF (RosettaNet Implementation Framwork).

        <arvola>

        As part of the investigation for the feasibility of layering RNIF
3.0 on top of ebMS, the RosettaNet engineering team has looked into the
mapping between RosettaNet message headers and ebXML message headers.
However, that analysis does not really compare ebMS features agaist those of
RNIF.

        </arvola>
