Think about some more loosely coupled applications than remote procedure call: data mining, for example. In data mining, the application that reads through the data does not care what the intention was of the process that wrote it, which is probably long since dead. And it may place an entirely different *pragmatic* on that data. Now extend this notion to real time, where you have processes that are steadily churning out knowledge to consumers that can do whatever they want with it. For example, Reuters Health narrowcasts news articles each day to its customers, but does not care what they do with them: the articles can be displayed as-is on a customer Web site, incorporated into a database, or printed out for use by a human editor. > How can a process select the data it will work upon without a priori > knowledge of the semantics of the element types. This is the place where WP and I still butt heads. I think I see his point of view, but I'm not clear enough on it yet to actually state it. -- John Cowan jcowan@r...
