It's been a while since I last provided an update on the standardization of DPWS, WS-Discovery, and SOAP-over-UDP. I'm pleased to say that the standardization committee has produced Committee Specification versions of these three specs--that doesn't mean that they're standards, but the committee has finished with these versions and has sent them to the greater OASIS community for an approval vote. The TC has a more detailed announcement.
Even though these aren't approved standards, we can still compare the technical details of DPWS v1.0 (the version originally supported in Vista) to the latest revision of DPWS v1.1 to see what has changed.
I also want to call out one big change to WS-Discovery:
Now, there are many changes I'm lumping into that category of "numerous smaller changes" which could each be broken out into their own articles--but the items I've listed above are the ones I'm most excited about. In the future I expect to dive into these (particularly security) in much greater detail.
Stay tuned for additional updates as the OASIS member vote on these specs gets underway.
