9 IFLA Library Reference Model (IFLA LRM), pomemben korak k sodobnim bibliografskim informacijskim sistemom IFLA Library Reference Model (IFLA LRM), an important step towards modern bibliographic information systems Maja Žumer Oddano: 20. 3. 2017 – Sprejeto: 26. 4. 2017 1.02 Pregledni znanstveni članek 1.02 Review article UDK 025.3 Izvleček V članku je predstavljen model IFLA LRM, ki je rezultat harmonizacije in uskladitve treh modelov družine FRBR. Model LRM je splošen in abstrakten in predstavlja pred- vsem okvir, znotraj katerega lahko načrtovalci informacijskih sistemov razvijajo kon- sistentne razširitve. Za definicijo modela LRM je bil, v skladu z modeli družine FRBR, uporabljen entitetno-relacijski formalizem. V članku so prikazana uporabniška opra- vila, ki so osnova za razvoj modela, sledijo definicije entitet in primeri atributov in re- lacij. Posebej je opisano modeliranje agregatov, ki pogosto predstavlja problem. Gre za prvo predstavitev modela v slovenščini, zato terminologija še ni uradna in dokončna. Ključne besede: IFLA LRM, FRBR, konceptualni modeli Abstract IFLA LRM model, the result of the harmonisation of FRBR family of models, is pre- sented. LRM is a high-level abstract model and serves primarily as a framework for the development of consistent extensions. The entity-relationship formalism, the same as in the FRBR family, was chosen for the definition of the model. User tasks as the basis of the model are presented first, followed by the entities and examples of attributes and relationships. Aggregates are specifically addressed, since they often present a modelling problem. Keywords: IFLA LRM, FRBR Family, conceptual models
