Il dibattito su FRBR library reference model è basato sul testo 2016 destinato alla worldwide review. Si mettono in evidenza alcuni aspetti innovativi di FRBR-LRM rispetto ai precedenti modelli dellafamiglia FRBR e si espongono alcune considerazioni che hanno condotto il Consolidation Editorial Group ad adottare proprio queste soluzioni. FRBR-LRM aggiunge una struttura gerarchica tra le entità che permette l’ottimizzazione di relazioni e attributi. In fase di implementazione, il modello può essere ampliato con l’aggiunta di attributi e relazioni, elaborando sottotipi di entità e relazioni. Le definizioni delle quattro entità ‘opera’, ‘espressione’, ‘manifestazione’ e ‘item’ sono state riformulate in modo da farle rimanere indipendenti, senza riferimenti reciproci, anche se rimangono immutati i loro significati e ruoli nel modello. Ove possibile, FRBR-LRM preferisce le relazioni agli attributi e, in questo modo, riduce considerevolmente il numero di questi ultimi.

Abstract
This discussion of the FRBR library reference model is based on the text issued for world-wide review in 2016. It highlights some of the areas in which FRBR-LRM innovates with respect to the previous models in the FRBR family and provides some of the considerations that led the Consolidation editorial group to the solutions adopted. FRBR-LRM adds hierarchical structure among entities which permits the streamlining of relationships and attributes. The model can be expanded for implementation through the addition of attributes and relationships and by sub-typing entities or relationships. The definitions of the four WEMI entities were reworked so as to stand independently, without reference to each other, still covering the same essential meanings and roles in the model. FRBR-LRM prefers relationships to attributes when possible, which considerably reduces the number of attributes.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
