Document vs. RPC

[remko de knikker]

Often, one makes a decision to develop RPC or Doc oriented services. 
That's what I did. Since interoperability and uniform data format was a 
key factor, I chose DOC.

But now I am trying to develop choreographies, I discover that there not 
a lot (none?) (open source/free) choreography engines that support DOC 
oriented choreographies and use choreography standards 
(BPEL4WS/BPML/WSCI). (Although I think that the whole purpose of the web 
services concept is defeated by RPC style, but anyway...)

Does anyone know of such tools??

In any case, it might be worth while considering, for people who are 
weighing one against the other..
