Web Services Based Education Resources Transmission And Service Model

E-learning is the hotspot of the international and domestic education development. Also it is the main direction of distance education development. In order to effectively build all types of educational resources bases at all levels, promoting the sharing of data between the educational resources bases, the research and development of transfer strategy and services system has become the key to the continued development of the E-learning. Such a system is essential to improve the searching efficiency of educational resources and retrieval accuracy. Also it can ensure the quality of construction educational resources.The service of educational resources is based on Learning Object Metadata Standards and Content Packaging Specification. It is a series of integrated activities such as educational resources storage, management, publishing, searching, retrieval and repeated using. The implementation of these activities relies on effective educational resources transmission and exchange of information. Educational resources are the core of the services. The method of resources'standardized description, packaging and transmission mechanism is the focus of the search.Aiming at actual problems the thesis proposes a model of transfer strategy and services of the education resources based on web services. Using Learning Object Metadata Standards and Content Packaging Specification realized the standardization of the educational resources. After that, the thesis proposes a transfer strategy based on web services to exchange educational resources information between sub systems. Combining distributed computing, web services, XML and its storage technology, the paper implemented prototype system model, thus achieved the purpose of sharing educational resources fully. The paper hopes the prototype system by packaging can be used into practical E-learning environment and can be helpful to the promotion the further development of our E-learning.
