IFLA Library Reference Model (LRM) is a high-level conceptual reference model developed within an entity-relationship modelling framework. It is the consolidation of the separately developed IFLA conceptual models: FRBR, FRAD, FRSAD.

IFLA LRM was developed to resolve inconsistencies between the three separate models.


The LRMoo model brings the IFLA LRM into the CIDOC Conceptual Reference Model (CRM) family of models by providing an object-oriented version of the model that is designed as an extension to CIDOC CRM.



PRESSoo is a formal ontology designed to represent the bibliographic information about continuing resources, and more specifically about serials (journals, newspapers, magazines, etc.). It is an extension of the FRBRoo model (Functional Requirements for Bibliographic Records – Object Oriented).
