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.
