Scope note

This is an abstract property – do not use it in profiles !

As a high level meta-property the present property expresses the fact that the range class is an identity defining component of the domain class This means that the identity of the domain class instance depends on the associated range class instance and no alternative instances are allowed for this property against the general rule of CIDOC CRM.

E.g. in the case of a Birth – E67 there can be no discussion about the person which is P98 brought into life by a specific instance of a birth. A specific instance of a birth is always related to just one person (or a limited range of persons in the case of twins, triplets, etc.). A discussion (and therefore production of alternative property instances) can take place concerning the P97 from father  property or the birth place, but never about the P98 brought into life property. This is necessary to allow data consistency in an information system and avoid considering e.g. the same birth instance as the birth of five different people which makes discussion impossible about the mother, father or birth place of one specific person.

This property has no direct instances but is used to specify the role of the instanciated subproperties as identifying properties for the domain temporal entity.
