Nowadays, many standardization organizations are working hard at the standardization of Educational resources because of their complexity and variety. Courseware is an important part of the teaching resource. Constructing standardized courseware which has good reusability and interoperability is important point of Education information. This paper apply the technology of domain ontology, mapping the courseware resources model into the relationship between concepts in the domain of courses in the course model, and using OWL ontology web language combination of LOM metadata standard attributes to describe the attribute of courseware. This paper introduce the concept of learning objects, treat courseware as a learning object, try to use the feature of learning object to improve the reusability and interoperability of the courseware. Through the use of technology of domain ontology, technology of learning object, we can get high reusability, interoperability, and easily sharing courseware. This paper production system designed two components called “the search of learning object” “the import of learning object” to
