Welcome to the forum!!
I�m very interested in the web services choreographies and orchestations; I�ve read a lot but I still have some important doubts.
1. Suppose we have a choreography description language, with which we describe a global model from a choreography that is formed, for example, by a travel agent, a flight agent and a visa service. Ok, if I have the global model, it�s supossed that I have a relation, in that model, between some "actions" and the wsdl operations from the different services that are interacting. If I try to interact with the travel agent, "by the choreography", should I invoke literally in my code the "choreography action" or the "wsdl operation". And, if first, then should I generate the stub for the choreography information?
2. In the case that I want to create any software for using choreographies, what should I do? I mean, should i generate a software that Knowing the choreography and knowing the invocation controls if all works fine? Or should I construct a software that reads the choreography and writes a code, in my programming language, that controls what it sais?
3. About orchestation I wanted to know if the same things are aplicable.
Thanks in advance and have a nice day,
Guadalupe Ortiz

Hi,
I don't pay much attention to this stuff because it seems like its putting the cart before horse .. we still need to work out the basics of endpoint communications before going into this next tier. Of course that's just my opinion, which is obviously not shared by everyone. ;-)
