WS-Spec Workshops are events, sponsored by multiple vendors, that give you the opportunity to learn about advanced Web Services specifications (WS-* specs) and to offer feedback and input to improve future drafts.
There are two types of events: Feedback Workshops and Interoperability Workshops. In Feedback Workshops, the authors of a specification discuss the content of the specification and solicit feedback from attendees. Interoperability Workshops are hands-on workshops primarily aimed at developers of companies who have developed implementations of a particular Web Services specification. These developers gather to test the interoperability of their implementations with others and provide feedback to the specification authors.
