Which statement best describes the relationship among attribute managing transformers?

• A. There is no overlap in their operations
• B. There is significant overlap in their operations
• C. They cannot be used together
• D. They only modify attribute names

Answer: (B)

Manipulating attributes in FME involves several transformers that share similar capabilities: they can create new attributes, rename existing ones, remove attributes, or compute values based on current data. Because of these overlapping abilities, there’s a lot of overlap among what these transformers can do. This overlap is intentional, giving you the flexibility to layer multiple attribute-managing transformers in a single workflow to build up the exact attribute set you need. You can rename something and then derive a new field from it, or create several attributes and prune the rest in subsequent steps, all in one pass. So the best description is that their operations significantly overlap and they are designed to be used together to shape attributes as required.
