AttributeExposer
- FME Attributes and more obscure Format Attributes that aren't automatically shown in Workbench.
- Transformers, such as the SchemaMapper, that dynamically add attributes onto features which Workbench is not aware of.
The input features are not modified in any way. This transformer only exposes the attribute in Workbench. It is up to you to ensure the attribute is created or read by the upstream workflow.
Note: Exposing fme_basename or fme_dataset will not change the behavior of the reader. To get these attributes added by the reader, you need to expose them where the read occurs, that is, in the reader feature types or the FeatureReader transformer.
Once the attributes are exposed, they can be used by downstream transformers.
Input Ports
Input
Features with attributes.
Output Ports
Output
Features with exposed attributes.
Parameters
Attributes to Expose
After you place the transformer, you can type attribute names or choose them from the drop-down list. The order in which they appear in the list is the order in which they will appear in the Output port of the transformer.
Editing Transformer Parameters
Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click 
beside the applicable parameter. For more information, see Transformer Parameter Menu Options.
