When a modeller imports metadata into Framework Manager, the Usage property for a non-indexed, numeric query item is set to which of the following?

When importing metadata in Framework Manager, non-indexed numeric query items are automatically assigned a Usage property of 'Fact' because numeric values without indexes are typically used for aggregation (sums, averages) in reporting. Indexed numeric values would be 'Identifier', and text values would be 'Attribute'. This default behavior helps modellers quickly organize their model.
