RE: Why XML for Messaging?
Hello Len, The rich clients seldom discussed here are the game and real time 3D clients. XML is trapped here in a document/forms mindset due to our origins in document and database technologies. Didier: Its even worse, we do not actually have common rich apps defined from XML and running on clients. We are still trapped in the mainframe world. A 3D component can fit into a 2D layout form. Since our screens are 2D and based on virtual screens (i.e. windows) then then 3D components can be embedded into 2D layouts (may even take the entire screen). Moreover, this 3D component can be collaborative and trigger events to be used by other components. The simulation and game clients are rich, use messaging, and transfer objects. Distributed systems such as XMSF are already doing much of this. The Blaxxun SharedEvents extension is already doing this. Didier: I tried googling for XMSF but got a lot of garbage. Any link? The language of the next generation is the language of the *viewpoint* (not a philosophical viewpoint: a virtual camera++). Thus, not XAML or XUL. Didier: Maybe Len, but we are still in the dark ages. To move to new UI paradigms we need a renaissance.... XAML and XUL or any other framework allowing us to use the processing power of clients in a necessary step. Don't forget that we seriously regressed on that front in the last years. Another point, my numerous hours in the usability lab taught me that unless we have better input devices. Navigating in 3D is really not easy with a mouse. Maybe we need a new device like a glove and a gesture language. Or even better a sensor able to recognize the gesture. Games will probably be the first to use such devices. But games like applications are expensive to install on each and every workstation in a company. Here us what we need: a) Software that can be downloaded from the web without any installation costs. Centrally delivered and automatically delivered from there. b) Software using the local processing power. Servers should be common data storage not application processors. Speaking and hearing with our community lead me to observe that the current state of the art is: a) applications running on servers, b) clients reduced to the role of terminals and like one of our colleague said in this group. We do this in color and animations. Small improvement over 3270 terminals :-) We need to bring rich apps with reduced cost of ownership to users. Then, from there progress will resume. We regressed for the "reach" with "poorer" applications. We now need to keep the "reach" with "richer" applications. Cheers Didier
