Digital library and Distance Learning Web service based Middleware: Specifications and Applications

Efforts for next generation digital library and e-learning architectures are aiming for a transition from these systems as integrated, centrally controlled systems to dynamic configurable federation of library and educational services and information collections. So, developers adapt their systems to novel technology trends and developments including technologies like Web services and the grid as well as the success of new paradigms like peer-to-peer networking; and also, service oriented architectures. Systems have major drawbacks because of their limitations in scalability, availability, distribution of computing power and storage system, as well as sharing information between users that contribute in these systems. Proposing a grid DLEL middleware, we described how some new technologies including agent, Web service and grid and emerging standards can be applied to digital library and e-learning
