OGSA Service Model

The core of the OGSA service model is a PortType containing operations each of which an OGSA compliant service, otherwise known as a GridService, must implement. These operations define functionality common to all OGSA services. They are as follows:

• findServiceData - An operation which returns information describing the service.
• setServiceData - An operation which allows modification of the service and of the information describing the service. A compliant service need not be modifiable in this manner.
• requestTerminationAfter - An operation which requests that the service's termination time, the time at which the service becomes non-functional, be changed. The request specifies the earliest desired termination time.
• requestTerminationBefore - An operation which requests that the service's termination time be changed. The request specifies the latest desired termination time.
• destroy - The destroy operation requests destruction of the service instance,
