I am off to Shanghai, China, to present a paper at IEEE SCC04 that Jim and I wrote few months ago. The paper is called “Assessing the Risk and Value of Adopting Emerging and Unstable Web Services Specifications” and a version of it is available as a Computing Science Technical Report (CS-TR-851).
Of course, given the developments in the WS space, the data in the paper is already out-of-date. For example, WS-Eventing is now supported by IBM too, WS-Addressing is supported by Sun and the process seems to have started on a W3C group being formed. However, the general idea on how to assess the value and the risk of being an early adopter of a specification in your project is still valid.
After China I am going straight to Brussels for GGF12. More WS-RF discussions 🙁
