Note: A characteristic always has exactly one role, but it can be defined using fact types having multiple roles.


Example: The characteristic ‘driver is of age’ with this definition: “the age of the driver is at least the EU-Rent Minimum Driving Age.” The semantic formulation of this definition appears in the introduction to Clause 9 - Logical Formulation of Semantics Vocabulary."The characteristic ‘driver is of age’ with this definition: “the age of the driver is at least the EU-Rent Minimum Driving Age.” The semantic formulation of this definition appears in the introduction to Clause 9 - Logical Formulation of Semantics Vocabulary." cannot be used as a page name in this wiki.


Example: The fact type ‘shipment is late’ whose instances are actualities of shipments being late. There is one instance of the fact type for each shipment that is late.
