A WSDL document does not define operation semantics
I had to read this post a number of times to make sure that there wasn’t something I missed since I find myself agreeing with Mark 🙂 (just joking Mark… we’ve agreed before, I think :-). A WSDL document will not tell you anything about the semantics of an “operation”. WSDL is a contract for…

Discussion on OGSA adopting WSRF as its infrastructure and the “Search for White Dwarfs”
A discussion has taken place in the OGSA WG mailing list on whether the OGSA platform should be based on WS-RF. We contributed our views supporting the adoption of only stable specifications but the group decided in favour of WS-RF. As Jim said in a post to the WS-GAF mailing list, it’s time to compare…

“Why WSDL Is Not Yet Another Object IDL”
Jim and I wrote an article few months ago that was just published in the Web Services Journal called “Why WSDL Is Not Yet Another Object IDL“. We even had some feedback… “very poor” by James Greeve. However, he didn’t say why he thought the article was bad so we could get it right next…

Is it a Web Service or not?
🙂 Mark Baker blogs about “the iTunes music store and the non-browser Web”. He writes: So let me understand… ITMS is presenting an HTTP/URI based interface intended for use by automata, and not human-controlled browsers? How is such a thing possible?!

Eric Newcomer on UML and MDA
Eric posted some comments on the use of UML and MDA. This is the last paragraph of his post… (And no, I don’t think either UML or MDA is very well suited to using for Web services, either. Class diagrams are just not the right metaphor, since Web services are not object-oriented, and the interaction…
