Filling in a Description for your custom transformer is only useful if you plan to upload it to the FME Hub.

• A. True
• B. False
• C. It depends on whether you share it with others
• D. Only for internal use

Answer: (B)

Documenting a custom transformer with a Description is valuable even if you never publish it to FME Hub. That description serves as inline documentation you and others can rely on later, detailing what the transformer does, the expected inputs and outputs, any assumptions or constraints, and practical usage notes or an example. This makes the workspace easier to understand and maintain, and it speeds up reuse or modification by teammates or your future self. The metadata lives with the transformer in the workspace (and can be seen in Workbench), so you gain clarity without needing to publish anything. If you later decide to publish to Hub, a clear Description also boosts discoverability, but the benefits are real whether or not you publish.
