According to the project site, The Flash/JavaScript Integration Kit "allows developers to get the best of the Flash and HTML worlds by enabling JavaScript to invoke ActionScript functions, and vice versa. All major data types can be passed between the two environments including: objects, arrays, strings, numbers, dates, booleans, nulls and undefined. The Flash JavaScript Integration Kit works across all major browsers and operating systems. It is released under an open license derived from the Apache 1.1 license."
The British Broadcasting Corporation (BBC) will be making its first foray into open source Flash by announcing the release of an open source Flash component set this Thursday at the London Macromedia User Group. The BBC's previous (and ongoing) open source efforts include the Dirac video codec and Kamaelia network testing platform.
The component set is called SMX Components, and contains components developed and used last year in the BBC News 2004 US Election Map application and, more recently, this year on the 2005 UK Election Map application. The latter contains the most up-to-date public versions of the components currently. Both applications have received rave reviews, with the Inquirer going so far as to call Flash the only winner in the US election in an article that features the 2004 US Election Map application. The 2005 UK Election Map is currently a Flash Film Festival finalist at FlashForward 2005 New York in the Application Category.
What was announced?
All of the Flash Conferences I've attended and spoken at this year have been absolutely amazing and FlashForward promises to carry on the tradition. Looking at the line-up there are so many speakers whose sessions I absolutely do not want to miss.
You can download the classes, a sample application and read more about it on the Using a SWF as a DLL page on OSFlash.
