Subject: RE: Proposal: A Registry Browser GUI tool

we with rr have always assumed we would use the trp protocols to access the
rr at least as one of the options. the other option is ldap ua.... for the
prototype i think that trp would be best.... rik

Nick is correct, the MS was designed to support RPC like behavior where a
sends an ebXML Message containing a "REQUEST" which results in an immediate
synchronous or asynchronous "RESPONSE". A scenario related to regrep would
appear as follows:

ebXML message REQUEST: I want your trading partner profile
ebXML message RESPONSE: OK; here it is

In the above scenario the ebXML header document in the REQUEST message
identifies the service (a.k.a. procedure) being invoked, in this case it
be a regrep service (e.g.  TPINFO) and the payload contains the "call
parameters" (e.g. DUNS Number of trading partner profile being requested).
RESPONSE contains an ebXML message indicating a SUCCESS status in the ebXML
header document, the payload  contains the requested information (trading
partner profile) in XML (tpaML).
