Building a Courseware Grid upon Dart Database Grid

DartGrid is developed by grid computing lab of Zhejiang University, which is built upon Globus toolkit and based on OGSA/WSRF standards, and has been successfully applied in data sharing for Traditional Chinese Medicine in China. In this paper, another application system built on DartGrid for managing courseware resources is introduced. The architecture of this system based on grid is open. The system consists of a series of equal grid-resource nodes. Files of resources need not be uploaded to one node as the c/s server, while the description information of the resources is registered. The salient aspects of this system are: (a) The special courseware ontology was defined as a standard for describing courseware resources; (b) The courseware grid service is to supply semantic registration, semantic query and so on. (c) Its client is a semantic browser.
