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).
A DWML document always contains two fixed feature types:
- head_metadata: This feature type contains the information from the header of the DWML document. There can only ever be one feature of this type produced from a single document.
- weather_by_time_and_location: This is the feature type that captures the core content of a DWML file. A single feature in this table contains a snapshot of weather conditions for a particular date and time at a location.
