RE: Active and Passive Mapplet
A mapplet can be active or passive depending on the transformations in the mapplet. Active mapplets contain one or more active transformations. Passive mapplets contain only passive transformations. When you use a mapplet in a mapping all transformation rules apply to the mapplet depending on the mapplet type. For example as with an active transformation you cannot concatenate data from an active mapplet with a different pipeline.
