Contrast with the Semantic Web initiative where there's Berners-Lee's vision of a web of machine-processible data built on the current web. As it's built upon existing systems a layered approach was sensible [1], and for it to be a *single* (global) web, development of a framework (RDF) was another sensible choice. Those things in place the roadmap is much clearer. There's a common language which can be used for creating more domain-specific languages which helps avoid the proliferation of task-specific syntaxes, the basic logical model allows more sophisticated languages to be built on top (OWL). Parallel and in part in concert with web service languages (esp. WSDL) the OWL-S language is being built on the existing framework rather than pretty much creating a from-scratch model X for every WS-X. It's irrelevant whether or not the Semantic Web vision is a pipe dream - it has encouraged coherence in development. Incidentally, I'm pretty sure all those individual WS-X models will be mappable into the RDF model as they are essentially based on many of the same ground rules - HTTP, URIs, domain-specific vocabularies, open world. I suspect longer term that WS-* may even need such a common model to unify what appear to be fairly disparate languages with only limited endpoints of intersection. So regarding WS-* : yes, I think it will be coherent, sensible and viable in the long term, given that web-natural selection will sort out what's actually needed, and there may be cross-fertilization and merging of these specs. But I suspect a lot of effort might have been saved had development started with something resembling a shared goal. Cheers, Danny.
