I wonder if the list might be symptomatic of there not being a shared 
goal, beyond a vague idea of distributed software built on XML. 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 

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.
