The OASIS international standards consortium today announced that its members have approved the Web Services Resource Framework (WSRF) version 1.2 as an OASIS Standard, a status that signifies the highest level of ratification. WSRF provides a generic, open framework for modeling and accessing stateful resources using Web services. The WSRF OASIS Standard comprises a set of royalty-free, interoperable, and modular specifications that make it easier both to define and implement a Web service and to integrate and manage multiple services. A Web service is characterized by the messages that flow to and from it. Any resource manipulated by the service, such as a shopping cart at an online retail site, needs to be identified and described by the messages that are exchanged. "WSRF solves the problem of how stateful resources can be represented and managed using Web service technologies," explained Ian Robinson of IBM, co-chair of the OASIS WSRF Technical Committee. "In particular, WSRF addresses the requirements of the Web Services for Distributed Management (WSDM) OASIS Standard and other industry standards to expose and operate on fragments of a resource's state, which is essential in resource-constrained or low-bandwidth environments." David Snelling of Fujitsu, co-chair of the OASIS WSRF Technical Committee, added, "The WSRF OASIS Standard provides a platform for many higher level WS Service applications including, but not limited to, management and Grid Computing infrastructures. Using WSRF, companies can provide a standardized, interoperable platform for resource-based Web services." WSRF is already experiencing a high degree of acceptance in the marketplace, including the open source community. "We already have thousands of people coding to the Globus implementation of WSRF," said Dr. Ian Foster, director of the Computation Institute at Argonne National Laboratory and University of Chicago, and a leader in the Globus Alliance, developers of the Globus open source implementation of WSRF. "The finalization of WSRF as an OASIS Standard will help accelerate adoption for interoperable distributed systems." "The WSRF OASIS Standard was developed to help simplify Web Services and make them more flexible. Together, WSRF and Web Services Notification (WSN), which is also advanced at OASIS, are enabling a closer connection between the Grid services and Web services communities," noted Patrick Gannon, president and CEO of OASIS. "We congratulate the members of the OASIS WSRF Technical Committee--as well as those who participated in the public review and who have already implemented WSRF--for all their work in advancing WSRF as an OASIS Standard." The OASIS WSRF Technical Committee remains open to new participation. All interested parties are encouraged to exchange information on implementing WSRF via the wsrf-dev mailing list online. As with all Consortium projects, archives of the OASIS WSRF Technical Committee's work are accessible to both members and non-members, and OASIS hosts an open mail list for public comment on the standard.
