n. (abbr. LRM)a conceptual entity-relationship framework for bibliographic metadata in linked data environments that expresses the logical structure of data to support library end-user tasksRDA 2016The RDA Steering Committee (RSC) agreed at its November 2016 meeting to adopt the draft IFLA Library Reference Model (LRM) as a conceptual model for the development of RDA: Resource Description and Access, replacing the Functional Requirements family of models (FRBR, FRAD, and FRSAD) that are superseded by the LRM.LoC 2020, 9LRM is intended as a guide or basis on which to formulate cataloging rules and implement bibliographic system ¶ The new version of RDA is a set of cataloging guidelines based on LRMIFLA 2021IFLA 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. Every user task, entity, attribute and relationship from the original three models was examined, definitions had to be revised, but also some remodeling was required in order to develop a meaningful consolidation. The result is a single, streamlined, and logically consistent model that covers all aspects of bibliographic data and that at the same time brings the modelling up-to-date with current conceptual modelling practices. ¶ IFLA LRM was designed to be used in linked data environments and to support and promote the use of bibliographic data in linked data environments.Miksa 2021, 99Most importantly, the LRM states and defines five generic user tasks—find, identify, select, obtain, and explore—as representative of the uses made of data by people during the information seeking process.
Notes
The Library Reference Model (LRM) consolidates and supersedes the separately developed IFLA conceptual models: Functional Requirements for Bibliographic Records, Functional Requirements for Authority Data, and Functional Requirements for Subject Authority Data. LRM is the conceptual basis for Resource Description and Access. The five library end-user tasks defined in the LRM are find, identify, select, obtain, and explore.
