In the coming months we will see a new wave of Rich Internet Applications that will blend the web application and the desktop application in exciting new ways. There are three technologies on the horizon that will change the way people use the web: LaszloSystems' OpenLaszlo, Microsoft's WinFX (codename Avalon) and Adobe's Flex 2.

OpenLaszlo

open laszloOpenLaszlo is a very intriguing technology. Originally it was built leveraging the Flash Platform, but has since announced that applications built in OpenLaszlo will be able to compile into DHTML/AJAX as well as Flash. In fact the first option will be to use the DHTML version. The language is XML based with some JavaScript abilities, which makes building the applications very easy. The versatility of being able to leverage Flash or DHTML is also a major plus. It is entirely open source and the use of XML and JavaScript makes it a good way to get started building Rich Internet Applications quickly. 

If you're interested in seeing OpenLaszlo in action, they have a good demo app - LaszloMail.

pandoraAlso check out Pandora, a 'web 2.0' application for finding music, which uses OpenLaszlo. The CTO Tom Conrad gave it great wraps in a blog post last August:

"Eight months ago when we sat down to figure out how were were going to deliver a compelling zero-install discovery and listening experience across Windows, Mac, and Linux in record time we considered everything you can imagine: plain old HTML, AJAX, Flex, OpenLaszlo to name just a few. In the end, Laszlo was the clear winner on all fronts. Mature, reliable, and the perfect tool for the job."

WinFX

win fxWinFX, specifically the Windows Presentation Foundation formerly code-named Avalon, is the biggest question mark of the three. It is Microsoft's answer to the Rich Internet Application space, and it's interesting because in many ways it's the Bigfoot of RIAs. It uses the .NET platform and via an XML markup language (XAML) it provides developers with an easy way to build powerful user interfaces for all kinds of applications, both web and desktop. 

As with other Microsoft technologies it will be limited to Windows machines. However it opens up the Direct3D platform to developers - which is going to make for some amazing user interfaces. The .NET community is huge, and WinFX is going to be the backbone of Windows Vista, meaning that it will be an easy way to deploy applications for a brand new operating system. Real world examples are scarce because Avalon hasn't been released yet, but you can see it in action by downloading Microsoft MAX. There is also an interesting white paper on the MSDN site about using Avalon to create a North Face In-Store Explorer. You can also get the beta and see what WinFX has to offer.

Flex

flexThe final technology, and the one I (Ryan) am admittedly most excited about, is Adobe's Flex 2. It too uses an XML based language (MXML) and as to be expected leverages the Flash Platform. Adobe/Macromedia's first foray with Flex required a very expensive server and had limited adoption. This time, Adobe has opened the floodgates and made the Flex 2 framework totally free. The new version of Flex will require a new Flash Player, and Adobe has rewritten the Flash virtual machine with a focus on speed and dependability. They're releasing the new player for Linux and Mac in addition to the normal Windows version, so the potential audience is huge. 

yahoo mapsAdobe has built a Flex-AJAX bridge, which brings the best of AJAX and the best of Flash together to create some awesome potential. Adobe also has 'Apollo' in the works, which will allow developers to access desktop APIs using Flex or JavaScript to deploy desktop/web hybrid applications for times when data needs to be stored offline. Flash is grown up from the days of 'skip intro' and has the potential to provide a great user experience. 

Yahoo Maps - which recently got TechCrunch's vote as the best mapping framework on the Web - uses Flex 1.5. Also check out the Flex 2 Style Explorer, which provides a way to see the power and customization of Flex (requires the Flash 8.5 beta 2 player).

Summary

All of these applications are taking the tenants of Web 2.0 - the collaborative spirit, the user generated content - and combining them with a focus on the user experience, which is so important to the desktop. AJAX has done a stellar job of making people think about the web in new ways. The technologies above are going to take that to the next level, by providing a desktop-like interface to web users. 

Rich Internet Apps allow sophisticated effects and transitions that are important in keeping the user engaged. This means developers will be able to take the amazing changes in the Web for granted and start focusing on a flawless experience for the users. It is going to be an exciting time for anyone involved in building the new Web, because the interfaces are finally catching up with the content.

The apps have been very slow to load, render, and are cumbersome to use due to the lack of responsiveness.

This has really changed for the better with Flex, and in fact, it's causing me to get back into CFML in order to make the most of the two. The resurgance will definitely help Adobe sell more ColdFusion licenses :)

Simply put, I'm really excited about this "new generation" of Flash apps. Flash always had potential, but it's never been truly realized until now. Good things come to those who wait, I presume...

I am covering similar topics on my India-centric blog that focusses on Information Technolgoy and the Internet, both of which are stirring up a revolution in India.

I had blogged on Mumbai Navigator, a tool very similar to Yahoo Maps reviewed above. http://india-it-pulse.blogspot.com/2006/04/

Nice write-up. It's perhaps worth noting that OpenLaszlo will also compile to the new Flash player.

Please forgive one nit: I think you meant "tenet" not "tenant":

And you're right about OpenLaszlo, which is one of the reasons it's interesting to me. People can write applications and then depending on their audience/need they can produce it in Flash or DHTML/AJAX. It's a cool technology!

Thanks for reading.
