Abstract: Web Service is the stateless service. When the web based experiment platform is designed, lots of experiments, especially the interactive experiments, make some intermediate state.And the state transition among these states is inevitable. Therefore, WSRF specification is used to manage the states , which are defined as the stateful resource. And duing to the problem of state transition among these states,we have designed an state transition management interface,based on WSRF, to manage state transition of the stateful resources.Then an example, a serial port communication, is given to specify the state transition interface in the end of this paper.
