The Model Design and Function Realization of Network Courseware Edit & Producing System

This paper discusses the framework and design method of network courseware Edit Producing system. In view of the poor share and the complex process of network courseware ,the paper provides network courseware metadata catalog model and content packing model based on Extensible Markup Language (XML),realizes the purpose of supporting the distance education standard ,then solves the problem of resource share and data exchange; and it adopts multi-track information organization based on timeline, can synchronize and integrate video, audio, power point (PPT), lecture and catalog at one time ,simplifies the process of network courseware and improve the efficiency of process.
