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).
Features read from MongoDB consist of geometry and a series of attribute values. The feature type of each Elasticsearch feature is as defined in the Reader Feature Type parameters.
Features written to MongoDB have the destination database as their feature type, and attributes as defined in the MongoDB Writer: Feature Type Parameters.
MongoDB attribute names and values support full UTF-8.
MongoDB attribute types are listed in MondoDB Writer: User Attributes.
