From FRAD 5.3.4 Relationships between Families
The relationship between one family and another that descended from the
first or is the predecessor to the other.
Descendent Family Descendent Family
This is usually expressed in authority data through links between the
authorized names given to each entity (see also references),
cataloguer’s notes, and/or information notes:
The relationship between the family known as the House of Condé and the
family known as the House of Conti which is descended from it.In CRM and
thus in FRBRoo familes are modelled as groups.
E77 Persistent Item <=E39 Actor <= E74 Group
The relationship between families as given in the example could be
modelled as a transformation, would that make sense?
Since in CRM E74 group is used to model all kind of family relations
between persons, it is of cause possible to model all relations between
familes as groups of groups. However, to me this has a flavour of
introducing a E1: P0 any relation E1 and a P0.1 type of relation.
