COMPONENT-ORIENTED ARCHITECTURE FOR WEB MASHUPS

摘要

A component-oriented web mashup system and method for communicating between component-oriented Web gadgets to facilitate secure Web mashups. Embodiments of the system and method redefine the traditional definition of gadget to mean a Web component having a verifiable controlled communication channel (a CompoWeb gadget). A CompoWeb gadget is created and defined using new HTML tags and global script objects and functions that extend the functions of the browser. CompoWeb gadget content is treated as a component that is isolated from other gadgets and frames by a browser, and only those allowed access can view data and code therein. Called functions of a CompoWeb gadget are run in the callee's environment instead of the caller's environment. This adds security, because all the requesting CompoWeb gadget receives is the run result. Embodiments of the system and method also include delayed binding of CompoWeb gadgets, such that binding is performed at run time.
