Adobe Systems on Monday is expected to release an alpha version of AIR on Linux and announce that it is joining the Linux Foundation.
AIR is Adobe's software for running and creating Web applications that run both online and offline. AIR 1.0, released late last month, runs on Windows and Mac OS. Adobe had said it will port AIR to Linux and then mobile devices.
As part of the AIR-on-Linux release, Adobe is making an update to the alpha version of its Flex Builder framework for Linux. Both will be made available at Adobe Labs for free and will be completed later this year.
Adobe said that it joined the Linux Foundation to help promote rich Internet application development on Linux. It's a bid to raise its commitment to Linux-based software on the desktop, where it's support until now has been limited.
Adobe has also sought to work with open-source software more, in general. It has open-sourced development tools, including its Flex development framework, and contributed a scripting engine to the Mozilla Foundation for inclusion in the Firefox Web browser.
