[Bijan Parsia] An aside: I conclude from Drew's lack of response that I can declare victory :) A more plausible conclusion is that I'm drowning in e-mail. I have had an amazing number of offers to share some money left by retired (and coincidentally deceased) African dictators, and I expect to become very wealthy in the near future. [Sudhir Agarwal] > in my opinion, it depends on, who is controlling the execution of C. I disagree. It depends on 1) what services the process occurances actually get instantiated to, and 2) how the service provider implements the advertized semantics. Someone, somewhere, has to care about 1. Someone, sometimes, other than the provider, might care about 2 but it may typically be the case that she can't know anything and needn't be bothered by the fact. Sorry I echoed your somewhere, somewhen, someone prosody. The puzzle seems to cry out for it. I am, of course, assuming that the semantics of these various alternative Drew puts forth all respect the semantics of the description under which P was selected. Indeed, if P was abstract, I can see P's occurences being bound to services from *two different providers*. I think we're getting somewhere. What do you mean by "the semantics of the description under which P was selected"? Is this description rich enough to settle the issue of what sorts of things P1 and P2 are? Where is the description to be found? What language is it expressed in? What is the semantics of that language? Take a simpler example. I do a series of GETs on an URI. I have NO CLUE whether I'm getting a single web server, something out of a farm, something from an intermediate cache or proxy. Nor do I care. Nor should I, in most cases. I certianly can *build* some of these distinctions in, perhaps, but the possibility of don't know, don't care needs to be preserved, and is probably the default. I'm willing to let stateless interaction be the default, as for the global atomic-clock service. I want to know how we indicate that we've strayed from the default. -- -- Drew McDermott Yale University CS Dept.
