RE: UDDI to ebXML RR mapping

[Waqar Sadiq <wsadiq@vitria.com>]

Matthew,

This is great.  I was thinking more about mapping basic UDDI concepts to the
equivalent RR concepts.  Just as an example, what in RR would map to a
tModel and so forth. I think it would be useful to make a list of concepts
from both specifications and then map them to each other, concept by concept
and attribute by attribute.  In the end, it would be great to be able to
implement UDDI model on top of ebXML model.

Thanks,

Waqar

Waqar,

We have been playing with UDDI since it became public, and just a few days
ago
I suggested internally at XMLGlobal that bridging UDDI to ebXML would be
relatively trivial assuming that the UDDI registry is complete, which it is
(test.uddi.microsft.com).  All that would have to be done is to build an
object
sort of like
the ObjectQueryManager object that this group has specified, except into
would
be called UDDIQueryManager, and it's methods or actions would correspond to
the
UDDI find and store methods, such as find_business, store_Tmodel, etceteras.
This object would accept payload and invocation requests over ebXML TRP, and
dispatch the queries on the UDDI registry either remotely with SOAP, or
locally
with a client library, and send the response back using TRP.

example query and response:


Content-Type: multipart/related; version=1.0; boundary=**bound**
Content-Length: 2286

--**bound**
Content-Type: application/vnd.eb+xml; version=1.0
Content-Description: ebxmlHeader
Content-ID: 0
Content-Length: 1466

<?xml version="1.0" encoding="UTF-8"?>
<ebXMLHeader MessageType="Normal"
   Version="1.0">
   <Manifest>
      <DocumentReference>
         <DocumentLabel>find_binding_req</DocumentLabel>
         ...
     </DocumentReference>
    </Manifest>
    ...
    <TPAInfo>
        <ServiceInterface>UDDIQueryManager</ServiceInterface>
        <Action>find_binding</Action>
    </TPAInfo>
    ...
  </ebXMLHeader>

--**bound**
Content-Type: application/xml; version=1.0
Content-Description: find_binding_Req
Content-ID: 1
Content-Length: 324

<find_binding serviceKey="uuid" generic="1.0" maxRows="99"
xmlns="urn:uddi-org:api">
   <findQualifiers/>
</find_binding>
--**bound**--

... and the response would have the uddi response XML body in the payload.
It
may make sense to modify the ObjectQueryManager to handle UDDI requests
internally to itself, I am more partial to simply bridging ebxml and UDDI
right
now.  The UDDI API is very straight forward and is very useful for discovery
of
trading partners and processes.  I saw a really neat demo at the UDDI
workshop
in Redmond of UDDI integration with a procurement app (Great Plains) that
made
good use of this API and registry, I very much hope that we can work the
UDDI efforts into ebXML, and would be willing to elaborate further toward
that
end.

Cheers,

Matt
