Entity definition

Definition from ISO/CD 10303-41:1992: An individual human being.

NOTE: Many countries have legislation concerning the identification of individual persons within databases. Although the intent of the IFC Model is to act as a specification for data exchange and sharing, an IFC file might in some situations be considered to be a database that enables identification of a particular person under the terms of such legislation. Users should be aware of the constraints of legislation that might apply in the places where IFC files are used.

NOTE Corresponding STEP name: person, please refer to ISO/IS 10303-41:1994 for the final definition of the formal standard.
