We have a workflow based application where a given process move from one state to another state based on User action.Currently our requirement is to have UI displayed its current state and allow user to take next action steps.So my question is does generally server tells UI the next actions that can be taken or the UI should decide based on current action? This application is designed using RESTful webservices.
The server should provide the client the next allowed actions, also known as state transfers, using links. Those links should, at least, contain two pieces of information: URL and relationship. The relationship tells the client the meaning of the state transition, allowing to recognize what it will do. The URL only says where to locate the service.
