STAC Metadata Format Attributes

In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Type Attributes), this format also adds format-specific attributes (Format Attributes).

To open Format Attributes, click the gear icon on a feature type in the workspace. Then click the Format Attributes tab. Format Attributes are applicable only to the selected feature type in the workspace.
