Its mandate was to explore the treatment of aggregates in the FRBR model. Common aggregates to be considered include: (1) Collections, selections, and anthologies, (2) Augmentations (original text augmented with illustrations, notes, introductions, etc.), (3) Monographic series, (4) Serials, (5) Multi-part monographs and (6) Integrating resources. Since aggregates are only briefly described in the original Functional Requirements for Bibliographic Records (FRBR) report, at the 2005 IFLA FRBR Workshop in Dublin, Ohio and at the FRBR Review Group meeting in Oslo in 2005, difficulties and inconsistencies in applying the FRBR model to aggregates were identified as an impediment to FRBR implementation. The Working Group proposed a general model for aggregates and identified three distinct types of aggregates: (1) aggregate collections of expressions, (2) aggregates resulting from augmentation, and (3) aggregates of parallel expressions. Each type is illustrated with examples.enhttps://creativecommons.org/licenses/by/4.0/Subject::AggregationSubject::Bibliographic conceptual modelsSubject::Conceptual reference modelsReportsInternational Federation of Library Associations and Institutions (IFLA)
