Maybe I don't follow, but this can't be "axiomatic" when one prominent use case for Web Services is to allow books to be ordered, schedules to be checked, etc. from very light wireless devices. >Web Services won't suport an advertising model, Again unless I'm misunderstanding, this appears to equate "Web Services" with RPC using XML and HTTP. Several of the posters in the xml-dist-app thread made the point that XML, HTTP, and SOAP (etc.) can be used to support alternative, asychronous communications and server-based coordination models. Consider a system that allowed suppliers to "advertise" available seats or rooms or books in a database or "XML space" via SOAP interfaces, and allowed consumers to request specific seats or rooms or books via another SOAP interface that generated a query to the shared DB or space. That would be a "web service," albeit one that uses a richer server-side coordination model rather than a simple "check every source via RPC and let the client sort it out" coordination model. Likewise, a SOAP interface that lets one use a cellphone to launch an "agent" that would run on a server, query multiple databases or websites for the best price on a specific seat/room/book, then e-mail back its recommendation, is still a "web service" to me. Sorry if I'm belaboring an obvious point ... [ordering books, checking schedules, checking stocks] >All these can get a better user interface from the client side - indeed, >they'll probably spawn the next generation of desktop applications, and >will be way more efficient as web services than as browser queries. On the other hand, I fully agree that the most realistic short-term use for SOAP/UDDI/WSDL is simply to do cleanly and interoperably with XML what is now done with all sorts of HTML and HTTP voodoo, hand-coding, and fragmentary documentation. When you have a fat client, exploit it!
