Methods and systems receive a service name, a service description, and/or operational steps of a service being registered. A first menu of previously established service class choices is provided in ranked order based on the service name, service description, and/or operational steps. Similarly, second and third menus of previously established class input/output mappings to inputs and outputs (required and produced by the operational steps of the service being registered) is presented in a ranked order, based on similar input/outputs of the selected service class. A fourth menu of previously established class transformations is provided in ranked order based on the similarity of inputs and outputs required for the operational steps of the service being registered, and inputs and outputs of the selected service class. The service is registered based on the selected service class, the selected class input mappings, the selected class output mappings, and the selected transformations.
