4] what is meta data? Metadata tags are basically compiler arguments which actually lets the compiler understand how the components are used in Flex application. In one of the questions you have asked what is [Bindable], this is one of the metadata tags in Flex. This metadata tag [Bindable] enables the variable as bindable one. i.e, when the variable value changes, then the places where this variable is referenced also gets changed. There are around 16 metadata tags in Flex. Some more examples are [Embed], [Remote], [Style], [Event], [Effect] etc.
