Of course with the current hype around Web services and SOA, there are a number of events hovering around this topic.
IBM is holding a series of SOA Days . The main SOA page for IBM products and trends can be found here .
Another event is the 2nd SOA and Web Services Best-practices conference in Chicago, and another is a workshop we are holding around the same topic at OOPSLA 2005, for the third year.
One of the main attractions of these and similar events are the battle stories we can exchange around SOA, which in the final analysis makes all the difference: what works in practice is the more important aspect of software engineering for clients.
