Which transformer creates a message for each attribute added to the original schema?

• A. AttributeCreator
• B. ChangeDetector
• C. SchemaScanner
• D. TypeChangeDetector

Answer: (A)

The action being tested is adding new attributes to a feature’s schema and then using those attributes to convey information. AttributeCreator is the transformer that introduces new attributes to features and assigns values to them. By creating a dedicated attribute for each added schema attribute and populating it with a descriptive message (such as the name of the added attribute or a note about its addition), you effectively generate a message for every new attribute in the original schema as data flows through the workspace. The other transformers don’t add new attributes or generate per-attribute messages: ChangeDetector looks for changes in values, SchemaScanner analyzes the existing schema without creating new attributes, and TypeChangeDetector flags changes in data types.
