Abstract
In 1998, the FRBR model (Functional Requirements for Bibliographic Records) was developed under the auspices of the International Federation of Library Associations and Institutions (IFLA). The library domain finally developed its conceptual model of the bibliographic universe and thus the basis for the development of novel bibliographic information systems. In 2017, the IFLA Library Reference Model (Riva, LeBoeuf and Zumer 2017) was formally accepted as an IFLA standard. The FRBR family of models as well as LRM all start from the user tasks that need to be enabled and supported by bibliographic information systems. The consolidation process included a detailed analysis of all entities, attributes and relationships defined by the FRBR family. In this paper, the main features of the model are presented and described. With IFLA LRM, we finally have a modern model, compatible with the semantic web.
