Based on modern international modelsWork, Expression, Manifestation, Item, Person, Corporate
Body (FRBR)Family (FRAD)
Work-Expression-Manifestation-Item are discrete components of a resource. This avoids duplication of dataE.g. Work creator and Expression language are linked to, not
copied in, multiple Manifestation descriptions such as a printed book and e-book
