It seems that the discussion about REpresentational State Transfer (REST) vs. SOAP as the preferred approach for service development is over for many people. There articles about SOAP being irrelevant seem less emotional and seem to lack the fevered pitch they used to have.
You look at the vendors though, and I don't see movement in this direction. One could review the offerings and speculate that a primary reasons vendors are spinning with SOAP is that have not figured out how to monetize REST. You talk with people developing RESTful systems and the point is they are solving business problems instead of using a technology. It turns the whole discussion towards solving a problem - what real SOA is supposed to do. I love that. That may be another reason the vendors are having trouble getting traction in this area; they need us to focus first on the technology stack.
