Experiences in implementing a cross-domain use case by combining semantic and service level platforms

We describe experiences of implementing a mash-up of two independent use cases, one operating in the embedded domain and the other in the internet messaging domain. We combine these service implementations on an existing Service Oriented Architecture (SOA) system with agents executing on a novel smart space architecture. Based on the lessons learned from this work, we sketch an approach for implementing similar use cases in a scalable and future proof manner by defining simple ontological concepts and associated behavior.
