Hi All, I would propose some text (section 2) linking this to SOFIA, for example: Interoperability of heterogeneous systems and devices has been a challenge in many areas of information technology (e.g. enterprise information systems, web systems, ubiquitous computing systems), and various technologies have been developed to support seamless collaboration between independent systems. In particular, techniques for creating common metadata vocabularies and ontological models (e.g. RDF [ ], OWL [ ]) have been developed under the broad term "Semantic Web". We envision that this trend will enter the machine control domain as well. An especially close technological area is smart environments, where Artemis project SOFIA [ ] is currently creating a semantic interoperability platform for ubiquitous device environments (e.g. smart houses). We will exploit the experiences and results of SOFIA especially in the developing of semantic-based interoperability between work machines in a smart work site. (Feel free to revise) If this is added, some wp should take this on its agenda, too. Regards, Kai
