Towards Building a Digital Library Service Metadata Model on the Semantic Web

In the current era of big data, digital library (DL) is migrating towards the directions of semantic exchanges and service interactions to facilitate DL users to search, share and reuse the digital resources in a more effective and efficient manner. This paper explores Semantic Web technologies for ontology-based modeling of DL service metadata across ubiquitous DLs, enabling to add semantics to DL services to address issues related to representation, cooperation and accessibility of services in or across the communities. In particular, the DL service metadata ontology addresses the dynamic behavior of a DL service by nesting the stateful changes, constraint rules and mapping rules to achieve the dynamic coherence for seamless service interoperability in the service lifecycle. The operation of the prototype system is demonstrated to validate the implementation of the proposed approach through access and visualization in a usage scenario.
