All in OGSA that gives emphasis to services are abstracted to services, and grid service is the basic con- ceptions of OGSA. After introducing the basic idea of OGSA, the framework system of OGSA was analyzed. The composition of grid service and the function of the representative standard interface were discussed. The creating course of the grid service instance was re- searched. A calling model of the grid service was put forward, and the processing course was described.
