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 topic.

DES features consist of geometry and attributes. The attribute names are defined in the DEF line and there is a value for each attribute in each DES feature.

The table below lists the attributes contained in all DES features.
