I personally believe that Event Driven Architecture (EDA) is the future. I don't believe that SOA can deliver many of the promises attributed to it without a heavy dose of EDA. Of course, to make this work, we need standards.
And that is where the Object Management Group's SOA SIG comes in. OMG has put out a Request for Information (RFI) on Event Driven Architecture to get feedback from the general community. If you are passionate about SOA, I strongly suggest you start with Brenda Michelson's excellent blog post on this RFI and go from there.
Time is short. If you wish to contribute, start today.
