In the personal or corporate spheres, the home/office of tomor- row is soon to be the home/office of today, with a plethora of networked devices embedded in appliances, such as mobile phones, televisions, ther- mostats, and lamps, making it possible to automate and remotely con- trol many basic household functions with a high degree of accuracy. In this domain, technological standardization is still in its infancy, or remains fragmented. The different functionalities of the various appliances, as well as market factors, imply that the devices that control them communicate via a multitude of different protocols (KNX, LonWorks, InOne). Building a high level middleware to support all the appliances seems to be a rea- sonable approach. However, market factors has shown that the emergence of a unique and universal middleware is a dream. To solve this issue, we have built a new generation of schizophrenic middleware in which service access can be generated from an abstract services description. EnTiMid, our implementation of schizophrenic middleware, supports various services access models (several personalities): SOAP (Simple Object Access Proto- col), UPnP and DPWS (Device Profile for WebServices). In this paper, we describe how these personalities are generated using a Model Driven En- gineering approach and discuss the benefits of our approach in the context of a deployment of new services at the city level.
