Somewhere my post on XAP got zapped. Let me recapitulate a little bit of it. XAP stands for Extensible AJAX Platform and is a part of the Apache Incubator. It is language independent on the server side, is UI toolkit neutral (Dojo, Kabuki), and allows you to write XML markup to define your UI. There’s more to it than that, of course. The architecture doc is very interesting.
Maybe XAP could become a standard for AJAX client engines.
