Linking Element - Basic Rule

Linking Element:
Basic Rule

The rules for multi-level description require that descriptions be linked to those of the level above them.
RAD does not say how this should be done, but some standardized method must be used to indicate where any given description is in the hierarchy and what its relationship is to other parts of the hierarchy.
Downward linking is not necessary: the Scope and Content should include that information.
However, an element must be included that indicates what series, sub-series, sous-fonds, or fonds the unit being described belongs to. Current practice is to place the 'linking' element above the Title element. Only show one level of linkage (as in the example provided)
