Feature Representation

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

FF features consist of geometry and attribute information. All FF FME features contain the ff_type attribute to identify the geometric type, as well as many common attributes. The attribute ff_type is required when writing to FF. Depending on the geometric type, the feature contains additional attributes that are specific to the geometric type. These are described in subsequent sections.
