Abstract: The LRMoo model brings the IFLA Library Reference Model (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. LRMoo is developed from FRBRoo, which was based on the FR family of models. In comparison to FRBRoo, LRMoo is streamlined and at a higher level of generality, while retaining full expressivity. Aspects of the model have been revised to align more closely with the IFLA LRM model, such as the handling of aggregation and representative expression attributes. Properties have been added to correspond to certain IFLA LRM relationships between works and expressions that were not declared in FRBRoo. The classes that represent the creation events of the main WEMI classes, F27 Work Creation and F28 Expression Creation, were revised. Specialized examples have been replaced with ones chosen to aid in comprehension of the model.
