Adobe Systems has announced its plans to open-source its Flex Web development framework.

The San Jose, Calif., company is releasing its Adobe Flex source code to the open-source community to enable developers throughout the world to tap the capabilities of Flex and participate in the ongoing development of the technology.

Flex is a framework for building cross-operating system RIAs (rich Internet applications) for the Web and enabling new Adobe Apollo applications for the desktop, the company said.

“We’ll be open-sourcing Flex with the next release of the technology, which is code-named Moxie,” said Jeff Whatcott, vice president of product marketing in Adobe’s Enterprise and Developer Business Unit.

Whatcott said Adobe will introduce the first public pre-release version of “Moxie” in June, “and we’ll be providing public daily builds of the technology starting at that time. We’ll also be launching a public bug database, so it’ll look, act and feel like an open-source project” even then.

However, the technology will not be open-sourced until “Moxie” is released in the second half of 2007—most likely in the fall, Whatcott said.

Upon release, the open-source Flex software development kit (SDK) and documentation will be available under the MPL (Mozilla Public License), Whatcott said.

Using the MPL for open-sourcing Flex will allow full and free access to source code, and developers will be able to freely download, extend and contribute to the source code for the Flex compiler, components and application framework.

Adobe will also continue to make the Flex SDK and other Flex products available under their existing commercial licenses, allowing both new and existing partners and customers to choose the license terms that best suit their requirements.

Whatcott said the MPL “strikes a good balance” for developers, particularly those who want to take a staged approach to working with open-source technology.

“This is the culmination of a long path toward opening up Flex,” Whatcott said.

I have it on good authority that Flex is going to be the Next Big Thing. If you like to stay abreast of web technology, this is the time to start gearing up with Flex.

Silverlight isn’t even an also-ran.
