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.

Please see the Writer Overview for details on how the features are converted into OSM elements in the OSM Writer.

Geometry
