Abstract. In an E-Learning environment, learning contents are usually organized through a series of courses, and the concrete learning contents are explained through various learning resources. With the development of ELearning systems and the passing of time, courses and learning resources will update, develop, and change inevitably. Because, in a discipline, the knowledge body can be divided into a series of knowledge points, so we proposed and designed a discipline oriented common knowledge ontology base (KOB) to organize and store all the knowledge points and their relations in a discipline. On the basis of KOB, we proposed a knowledge point based course developing model and a learning object metadata model. Through KOB, the knowledge points can be reused in different courses, so to improve the efficiency in courses developing, course contents authoring and contents updating. Furthermore, when a new learning object is registered to an E-Learning system or a learning object updated, through knowledge points mapping between courses and learning objects, it will be automatically reflected in according courses that have the same knowledge points with the learning object. So, on the basis of KOB, the work of courses developing and learning resources management becomes easier and flexible. Keywords: Knowledge Point, Ontology, Learning Object, Curriculum.
1 Introduction In the application of E-Learning, with the increase of courses, many problems became more and more prominent, such as those in curriculum developing, update of contents, the using and management of learning resources, and the maintainability and extensibility of E-Learning systems. Although many international academic societies and standardization organizations have issued a series of educational technological standards and specifications, including courses metadata model, learning object metadata model, contents encapsulation specifications, etc., their main purpose is to achieve the resources sharing and systems interpretability among various systems. But as for the relationship among courses, overlapping of courses contents, and logical relations between course contents and learning objects, present E-Learning standards haven’t involved them, and the related research is still a little.

With the development of a discipline, new courses constantly emerge, and the contents of old courses might often change; all of these require the expression of courses to own flexibility. Course contents are explained via learning objects, thus learning objects are the carriers of knowledge. One learning object could explain one or more knowledge points, and one knowledge point may be explained by more than one learning objects. In the present educational technological standards, metadata models related to learning objects could not yet reflect this kind of knowledge layer relations
