IMS-LD player based on B/S structure

IMS-LD editors accelerate the development of learning design, however, IMS-LD stand-alone player which restricts resources spreading becomes the obstacle of learning design. To solve this confliction a player application model based on B/S structure is proposed. By IMS-LD analysis we can get a conclusion that all the components and methods in IMS-LD are organized as tree structure. Entity Class and Session Class corresponding to components element and method element of specification respectively build the model of play application on server.
