8.1.3.5.1 Semantic definitions at the entity

This entity represents 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  Entity adapted from person defined in ISO 10303-41.

HISTORY  New entity in IFC1.5.1.

IFC4 CHANGE  Attribute Id renamed to Identification. WHERE rule relaxed to allow omission of names if Identification is provided.
