Rich Internet is a metaphor for this emerging notion of extending the client and presentation tiers and sort of escaping the Web browser and bringing a richer user experience and a richer data experience to the Web. So what it entails is a set of distributed, service-oriented applications with much richer data aggregation than (what) just html forms and html pages can offer, and much more richer, user behaviours and a much deeper level of interaction with the user so that the user has some semantic cues about what a given piece of data means and also a lot of cues about what the user wants to do with it and what the user is doing at any given time. So we conceptually view these as a hybrid of classic desktop applications and Web, browser-confined applications; they sit sort of conceptually between those and have a lot of the benefits of both.
