1. A system for creating a dynamic client side service proxy framework using meta-data and introspection capabilities of Open Grid Services Architecture (OGSA) service data comprising: a grid client; a defined Open Grid Service Invocation Factory configured to create a service proxy; an Open Grid Service Infrastructure (OGSI) service in communication with said grid client via a communications network, said OGSI service includes OGSI service based information exposed by the service and introspected by said Factory; and an OGSI Service Invocation Proxy defining a set of dynamic interfaces based on said service introspection and a meta-data inspection interface of said Service Invocation Proxy; wherein said Service Invocation Proxy exposes both static port type interfaces and dynamic interfaces to support more flexibility of the client; and wherein said OGSI service based information includes service data elements, port types, Grid Service Reference (GSR) values, and operation extensibility parameters.
