Agenda
What is Flex?
Elements of a semantic application
Flex and Actionscript Resources
Available Examples

What is Flex?
Flex is a framework for building:
Rich Internet Applications (RIA) – Browser-based applications that look like applications (running on Flash Player)
Desktop applications that run on Adobe Integrated Runtime (AIR)
Available as:
Free SDK: http://www.adobe.com/cfusion/entitlement/index.cfm?e=flex3sdk
Commercial Package: Flex/Flash Builder (Eclipse based IDE): http://www.adobe.com/cfusion/entitlement/index.cfm?e=flexbuilder3
http://www.adobe.com/products/flex/

Why Flex for Semantic Applications
Flex compiles applications that run on Flash Player – so what ?
Secure platform
Deploy globally
Substantial visual capabilities
Embodies 10+ years of design experience
Runtime is Free :) and Cross-Platform
Bottom-line easy to create and deploy visually engaging user experiences
