Where can you view the schema of the source data you start with?

• A. The reader Feature Type dialog
• B. The writer Feature Type dialog
• C. The Transformer Gallery
• D. The Navigator's writer entry

Answer: (A)

Viewing the schema of the source data is done in the Reader Feature Type dialog. When you configure a reader, this dialog lists all input fields (attribute names and data types) and the geometry the reader brings in, which is the source schema FME will operate on. The other options don’t show the input schema: the writer Feature Type dialog defines the output structure; the Transformer Gallery is a catalog of transformers; and the Navigator's writer entry shows how data is written, not the source’s schema.
