For many applications, the axes of rendering and behavioral fidelity are the exact reason for the application failing in the market or spiraling as, Alaric says, toward a single vendor solution. We've seen that in the web browser, we've seen that in Flash, we've seen that in VRML. X3D is being crafted with that problem in mind. XSLT doesn't fix implementation issues in the browser in the least. That is the reason for conformance testing. As to the triples datamodel and automated negotiation among agents, that problem is solvable although the cost of the solution is quite high as the AI researchers doing expert systems work can tell you. The scalability of the language or implementation is irrelevant to that cost. Also, the acceptability of outcomes of negotiation to the human owners of agents is the grinder. As the AI veterans told us, rationality is a weak predictor of human behavior, and in any set of processes pipelined, hierarchical, or some combination, the fact that the system itself is a source of human bias vastly complicates the prediction of the outcome and raises the costs. For some recent thoughts on that http://hbsworkingknowledge.hbs.edu/item.jhtml?id=4170&t=operations We are still a long way from believing in the deity of Colossus: The Forbin Project. len From: Elliotte Rusty Harold [mailto:elharo@m...] At 1:36 AM +0100 6/8/04, Alaric B Snell wrote: >...a web browser that gets deployed on millions of random machines >all over the place, then instead you get developers having to test >their HTML against a list of major browsers, and being wary about >including things like MathML, SVG, Java, Flash, etc. in their sites. >It appears that "in the large", these kinds of systems tend to end >up constraining the producers of content to a schema ("works in IE") >anyway. Again, this is based on the same fundamental fallacy that everyone must do the same thing with the same data. The reason we get into these test everywhere problems is because web designers are trying to make sure that everyone sees something pretty close to exactly the same thing. Provide well-formed content in XML (not Flash or Java, please) and offer one or more stylesheets that suggest a possible presentation; and you're good to go. That's the first step in the XML vision. It enables readers to read content in a straight-forward fashion, while still customizing their experience. It also allows the information to be repurposed for tasks go beyond mere browsing, without extra effort form the publisher. -- Elliotte Rusty Harold elharo@m...
