RE: Registry Submissions and Queries

[Peter Kacandes <Peter.Kacandes@ebay.sun.com>]

Just wanted to clarify and make a couple of corrections to my previous comments.

First off, what I meant to say was that there had been an IETF pre-BOF and BOF on SOAP, not an 
OASIS TC. Sorry for the confusion. Its hard to keep all of these things straight sometimes.

Secondy, its important to distinguish between SOAP and XML-RPC. I'm told that there are 
certainly situations where XML-RPC might be a good thing. Apparently, there was a presentation 
at the BOF on the requirements for XML-RPC. I'm further told that there was a comparison 
between those requirements and what is available in SOAP. I'm told that that is where SOAP was 
found to be lacking.

I'm further told that, when thinking about XML-RPC, the key thing to keep in mind is the 
degree of synchronicity and coupling. In situations where syncronous operations and tight 
coupling between systems is required, then XML-RPC could be useful. Alternatively, if the 
systems should be able to operate asynchronously and loosely coupled, then XML-RPC might not 
be the best way to go.

If its a "real time" system, then one might tend to think that that is a situation where you 
would want synchronous operations and tight coupling.

Again, seeing as I'm obviously not very familiar with any of these things, take the above with 
a large grain of salt. I think I'll keep my mouth shut on this topic from here on in.
