Title: The WS-Resource Framework (WSRF), January 2004. URL: http://www.globus.org/wsrf/ Comment: The OGSI framework has been recently refactored to define a family of related specifications that could be adopted on a piecemeal basis. This refactoring together with some extensions to keep pace with changes in Web services standards forms the WS-Resource Framework (WSRF) . Although OGSI and WSRF go beyond WSDL with the specification of several kinds of specialised port types and fault messages, unlike OWL-S, they does not attempt to describe the behaviour of Grid or Web services. In this sense, OWL-S is complementary to both these specifications.
