I'm not sure I follow you...  Are you saying that all of the
information in a library record can always be expressed with
triples with the same subject?  Even, for example, if FRBR

if I correctly infer, nicely captures the notion that a record
is focused on a particular resource without implying that all
of the information in that record may be expressed directly
as an attribute of the primary entity.
