Challenges in Building Semantic Interoperable Digital Libr..

After a decade of research and development, digital libraries are becoming operational systems and services. This paper briefly summarizes some of the challenges in building such library services. In building the Semantic Web enabled digital library sytem, the interoperability and scalability will be definitely the most important problem to be solved. To make clear the present status, I concisely make a survey on the functions of the interoperability-related protocols and standards in digital library field, such as z39.50, OAI, etc. In this paper, I divided the interoperability into syntactic level and semantic level. The semantic interoperability is the most complex set of challenges in the arena of building Semantic Web enabled digital libr ary system. Finally, I describe the key challenges we are now faced and also present my initial research approaches.
