As I've been looking at SOA governance solutions recently, I've been looking at a huge hole in the approach. While all SOA governance products do indeed consider the control and use of services, most are ignoring the data management issues, and thus are only solving part of the problem.
Services are really transactional behavior that fronts information, at their essence. While there are services that are built as true data services, and services that are more about transactional behavior, they are all services nonetheless and all must deal with, and manage information/data.
