Building consensus through blogging. Regarding the abstract concept of a WebServices Description Language, consensus is forming.
Jon Udell: Desirable? Hugely. I want this, everybody should want this
James Snell: the real question that needs to be answered is not whether WSDL is really necessary, but how WSDL can be improved to make it easier to write good interoperable implementations of it.
Simon Fell: I have no issues with WSDL the concept, its just a machine readable description of a SOAP endpoint. But I have lots of issues with WSDL the reality.
Going back to Dave's InfoWorld slides: Lay a thin cable, use it to lift a slightly bigger cable. Perhaps we were too ambitious and we need a smaller second cable. Sage guidance on what the important core of WSDL can be found here. Sounds like a good place to start!
