We need to make sure we’re focused on an area of governance for which a standard language could be applied. I think we’ll see much greater success if it focused on run-time governance and work backward in the development lifecycle. We (the software development industry) have a much better handle on the types of policies that should be exchanged between systems as part of service invocations. Trying to express policies that should be exchanged as part of developing a system is far, far more challenging, and will be much more difficult to standardize. What’s interesting is that the former item is much more about having standards/languages, whereas the latter is much more about process/methodology. If you want methodology for run-time governance, I think we’re already on the right track with WS-MetadataExchange. I’m pretty sure I was introduced to that by reading the whitepaper published by IBM & Microsoft entitled “Reliable Message Delivery in a Web Services World: A Proposed Architecture and Roadmap” in March of 2003. It can be found at: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnglobspec/html/ws-rm-exec-summary.asp That was obviously some time ago, and I’m sure most on this list are familiar with it. As a practitioner, I really look forward to the day when the platforms start to support this. Unfortunately, as Anne pointed out, WS-Policy is just a wrapper. Without domain specific policy assertions, WS-Mex won’t do us much good. -tb ------------------------------------------------------------------------------------- A.G.
