    Abstract
    Evolving from database models using punch cards, strict linear relational databases and predefined object-oriented data structures, the triple statements underlying Semantic Web technologies bypass many design constraints to offer endless flexibility. Overcoming structure is challenging, especially the relatively recent structure formalized in the Functional Requirements for Bibliographic Records (FRBR). Though geared to easier access and interoperability and recognizing a multilevel bibliographic model, FRBR remains tied to translating entity-relation diagrams to data structures. Resource Description Framework (RDF) provides a more flexible way to express concepts, in which bibliographic models may be thought of as graphs of properties and relationships. But even RDF-based models can undermine that flexibility by mixing concept classes and data structures. The advantage of RDF classes is to provide semantics that enable a user to focus on similarities, not bound by contextual constraints.and success metrics.

    Abstract
    The article analyzes the conceptual model of the Functional Requirements for Bibliographic Records (FRBR) as a general model of bibliographic data and description that can be interpreted, as needed, to serve the needs of various communities. This is illustrated with descriptions of five different implementations based on the concepts in FRBR: FRBRER (entity-relation), FRBROO (object oriented), FRBRCore (FRBR entities as linked data), (FRBR entities within the commerce model), and FaBiO (FRBR indecs as a basis for academic document types). The author argues that variant models show the strength of the FRBR concepts, and should be encouraged.
