What are objects in FME that let you change the content or structure of your data?

• A. Feature Types
• B. Tools
• C. Transformers
• D. Editors

Answer: (C)

Transformers are the blocks in an FME workspace that actively modify the data as it flows through. They take input features, apply operations to change what the features contain or how they are structured, and then pass the transformed features on. This covers renaming or creating attributes, computing new values, converting data types, altering geometry, reprojecting coordinates, filtering or splitting features, and generally reshaping the data schema. Feature Types describe the shape of data (its schema and geometry type) but don’t perform per-feature changes during processing. Editors and Tools are about configuring and managing the workspace rather than performing data transformations themselves. So the elements that let you change the content or structure of your data are the transformers.
