Karen,
FRAD and FRSAD are basically variants of SKOS and SKOS-XL. Foaf:focus is a key factor for connecting these back to ontological models. The authority section of the lld-xg report addresses this but may not be clear enough.

I should mention that I am keeping a wiki page [1] relating to the
various versions of FRBR in RDF, with links to discussions around the
issues of modeling -- in particular the question of defining the FRBR
classes as disjoint.
Also, FRAD [2] resembles FRBR in structure, but FRSAD [3] takes a very
different approach with only two classes, Thema and Nomen. An
interesting aspect of FRAD, which reflects standard library practice, is
that it retains the concept of a "controlled access point" and includes
a relationship to the rules under which the access point was developed
and the agency that created the access point by applying the rules.
If I run into discussions of these latter FRs I will add them to the
wiki page.
