A general learning management system based on schema-driven methodology

Although a number of learning management systems are running on the Internet, it is clear that they are not able to efficiently meet users' requirements, e.g. dynamically create and control learning activities and processes, and efficiently describe and use the semantics of learning objects and content. In this paper, we propose a schema-driven methodology to design a general learning management system supporting XML and Web-services technologies. This system is driven and controlled by schema processors, which provide the ability for users to freely generate and manage learning procedures such as replace learning activities. In addition, it can interact with legacy systems. We represent the procedures of controlling learning activities through schema management, such as dynamically establishing and allocating the main directories (e.g. the learning activity directory) from the central databases (e.g. the learning activity database) to a user in terms of his/her roles, sub-roles and requirements. This system can greatly improve the capabilities of existing learning management systems.
