To restate a point that apparently did not communicate to anyone,
I think that many conversational choreographies will be (are being)
stereotyped so that distributed objects can converse by using
a shared script of some kind. Most of the current efforts (ebXML BPSS,
BPML, WSFL, XLang) use XML.
Yes, most of the early scripts will be business-oriented, like order-
delivery-payment. But the principle applies to other domains: don't worry
so much about the particularities of the end points; have them follow a
shared scenario. Think rules of a game.
Hi, Bob: I don't want to push the choreography metaphor too much, but
is there a notation with which we can write the songs and express what
needs to be co-ordinated independent of the actual pieces of music
that are presently coming out for particular standards bodies such as
ebXML? (I think that would be one fruitful way of answering Adam
Bosworth's concerns about specifying the order and temporal semantics
of method calls).
Have fun,
Bob Haugen
