Feature Representation

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

All ZGF features contain the zgf_type attribute. The value for this attribute is set identically to the value of the feature’s feature type.
