Tableau Data Extract (TDE) Feature Representation

Features written to a TDE table consist of a series of attribute values. Features written to the TDE file have the output TDE file base name as their feature type, and attributes as defined in the feature type dialog.

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).
