A Linked Data-based Semantic Interoperability Framework for Digital Libraries

The growing popularity of the adoption of the linked data is increasing the semantic interoperability in the digital libraries era. The linked data principles provide an efficient way to interlink resources across diverse datasets. Several digital libraries around the world are publishing their legacy data from catalogs and authority files following the linked data principles. In this paper, we propose a linked data-based semantic interoperability framework for digital libraries. The proposed framework is based on three layers, supporting the data acquisition, linked data publication process and the building of value-added services for the digital libraries users. In order to evaluate the feasibility of the framework proposed, we have built a prototype as a proof of concept. The prototype demonstrates the effective implementation of wrappers as a data integration method to deals with the heterogeneity of the diverse data sources. Moreover, illustrates the importance of dealing with the quality of the bibliographic metadata form early stages of development.
