Developed through joint work in the library and museum communities, it is compatible with and an extension of the museum community model, the CIDOC Conceptual Reference Model (CRM). LRMoo version 1.0 is aligned with CIDOC CRM version 7.1.3. LRMoo is a high-level, compact model, with a minimum of hierarchy between classes. LRMoo is tightly aligned with IFLA LRM and reflects its decisions about scope and granularity. LRMoo supersedes FRBRoo version 2.4 (2016), the object-oriented model that was aligned with the superseded FR models: FRBR, FRAD, and FRSAD. Transition information from FRBRoo to LRMoo is included.enBibliographic conceptual modelsStandardInternational Federation of Library Associations and Institutions (IFLA)
