An Ontology-Based Model of Digital Libraries

摘要

In this paper a new unifying model is suggested for digital libraries which contains four conceptual layers, and defines the concepts of each layer as an OWL ontology. Instances of the ontology can be used to define an overall view of a digital library in terms of the four layers and the relationships between them. Such a model has the advantage that the methodology is formalized and extensible, thus models are comparable and manageable.
