unusual and hence controversial. Its proposed mechanism for adding state to web services runs contrary to what is widely perceived as the way forward for Service Oriented Architecture, the conceptual model that is currently being advocated as the best way to write large-scale distributed systems. However, from a Grid Services perspective, there is little new in the framework, as it is very much like OGSI. By refactoring the OGSI specifications, the framework does make it easier for Web Services and Grid Services to co-exist. This is important, as it will be some time before an implementation of WS-RF will be available. We can develop a SOAP interface that incrementally moves towards richer WS-RF support. Things that WS-RF depends on XML, XML Schema, XML namespaces. These are foundational and (mostly) non-controversial
