Mapping FRSAD model and other abstract models

IFLA FRBR Group 3 entities "represent an additional set of entities that serve as the
subjects of works" (IFLA, 1999: 16). A third IFLA Working Group of the FRBR family,
FRSAR (Functional Requirements for Subject Authority Records), was formed in April
2005 and charged with the task of developing functional requirements and a conceptual
model for subject authority records. One of the terms of reference is to build a conceptual
model of Group 3 entities within the FRBR framework as they relate to the “aboutness” of
works. In this framework all three entity groups as defined by the FRBR conceptual model
have the potential to be the subject of a work. In other words, Group 1, 2 and 3 entities all
can have an “is-subject-of” relationship with a work. The FRSAR Working Group
proposed an abstract conceptual model and presented it at the IFLA Conference in August
2007. The model was further discussed and developed by the Working Group in 2008.
The draft report prepared by the FRSAR Working Group has indicated that the focus of the
model is on the authority data instead of authority records, hence the abbreviation used in
the report is FRSAD, i.e., Functional Requirements for Subject Authority Data.
