 | Level: Advanced Contributors: IBM, Fujitsu Laboratories of Europe, Globus 01 Feb 2004 This paper explain the relationship between OGSI and WSRF and the related WS-Notification specifications, the common requirements that both address, and compares and contrasts the approaches taken to the realization of those requirements.
The Open Grid Services Infrastructure specification version 1.0 (OGSI), released in July 2003, defines a set of conventions and extensions on the use of Web Service Definition Language and XML Schema to enable stateful Web services. It introduces the idea of stateful Web services and defines approaches for creating, naming, and managing the lifetime of instances of services; for declaring and inspecting service state data; for asynchronous notification of service state change; for representing and managing collections of service instances; and for common handling of service invocation faults. In January 2004, the WS-Resource framework (WSRF) was proposed as a refactoring and evolution of OGSI aimed at exploiting new Web services standards, specifically WS-Addressing, and at evolving OGSI based on early implementation and application experiences. WSRF retains essentially all of the functional capabilities present in OGSI, while changing some of the syntax (for example, to exploit WS-Addressing) and also adopting a different terminology in its presentation. In addition, WSRF partitions OGSI functionality into five distinct, composable specifications. In this document, we explain the relationship between OGSI and WSRF and the related WS-Notification specifications, explain the common requirements that both address, and compare and contrast the approaches taken to the realization of those requirements.
