A Basic Introduction to FRBRoo and PRESSoo

In addition to FRBR, FRAD, and FRSAD, two conceptual models for bibliographic information were developed these last years: FRBRoo (a reformulation of the FRBR/FRAD/FRSAD models) and PRESSoo (more specifically devoted to bibliographic information about continuing resources). This paper provides the explanation that is necessary for a good understanding of the formalism used in these two models. It then shows how some of the basic constructs of FRBR/FRAD/FRSAD are rendered in the FRBRoo model. In a very brief third section, it highlights some core aspects of PRESSoo.
