ENGINEERING THE LIFE-CYCLE OF SEMANTIC SERVICES-ENHANCED LEARNING SYSTEMS

Service-oriented learning environments are the new paradigm for interoperability of learning management systems. They support a wider range of needs by integrating existing and emergent services, leading to an entirely new architectural design for such systems. The engineering life-cycle of resources and services can be enhanced and integrated in current and future virtual learning environments. This work defines a services-enhanced learning architecture and describes two levels of integration carried out to author, deploy and enact learning services from open web-based interaction protocols and semantic web service descriptions.
