Curriculum Design within a Semantic Information System

There is a demand for powerful curriculum design systems to support the representation, exchange, integration and sharing of curriculum data over the internet; to meet the requirement, this paper use ontology to describe the concepts and their relationships in a specific domain, with which the author annotate the data models, and make sure the data model has structural information as well as semantic information. In this way, data transformation in a semantic consistent way is supported and query formulation is facilitated in the process; an ontology-based description model is also proposed to give expression and organisation of curriculum information.
