When you drag and drop the ibiCanvas component into a Flex application, by default, ibiCanvas adds the Information Builders namespace, ibi, to the flex <mx:Application> tag, as shown in the code below.

xmlns:ibi="http://www.informationbuilders.com"

Note: All WebFOCUS Enable components utilize the ibi namespace prefix.

For SDK 4.x, Spark components are located in the ibis namespace. For example:

xmlns:ibis="http://www.informationbuilders.com/spark"
