This document discusses key questions around service-oriented architecture (SOA) including how services are discovered and matched, what information about services should be published, and how services bind together. Specifically, it raises questions about how to design a service broker to facilitate finding and publishing services, what criteria determine when one service matches the needs of another service requester, and how services connect and interact with each other.
