Functional Requirements for Bibliographic Records ( FRBR ) is
recommended by International Federation of Library Associations and
Institutions ( IFLA ) in 1998 to restructure catalog databases to
reflect the conceptual structure of information resources. FRBR uses an
entity - relationship model of metadata instead of single flat model
which existing catalogue standards followed. The model consists of four
levels of representation ; the work (a distinct intellectual or artistic
creation), the expression (the intellectual or artistic realization
of a work ), the manifestation (the physical embodiment of an expression
of a work) and the item (a single exemplar of a manifestation).
FRBR conceptualizes three groups of entities:
Group 1 consists of the products of intellectual or artistic endeavor; work, expression, manifestation and item (publications).
Group 2 comprises those entities responsible for intellectual or artistic content (a person or corporate body).
Group 3 includes the entities that serve as subjects of intellectual or artistic endeavor (concept, object, event, and place).
