The UDEF uses the basic information systems model that is described in ISO 11179, in which every item of data is characterized as being an instance of a property of some object class, represented in some way. The UDEF provides hierarchical categorizations of object classes and properties. The UDEF tag for an item of data is obtained by putting together the tags for the object class and the property of which it is an instance.
