A service-oriented environment for high-level communications between computer systems and smart embedded software components that enables even low-cost devices to cohere into a “web of objects” has been created by the EUREKA ITEA software Cluster SODA project. The technology emphasizes simplicity and ease of implementation as all devices in the web of objects communicate using the Web Services language. “With Web Services, you can directly connect your device to the ERP server without any intermediaries or protocol conversions or data manipulation,” says SODA project leader Francois Jammes. The earlier ITEA SIRENA project was the site of the development of the original proof of concept for embedding Web services in inexpensive devices. SODA devised the general environment to manage applications founded on service-oriented architecture, and the ITEA project established demonstrations of full application life cycles in a number of domains, such as industrial automation, telecommunications network and terminal management, and home automation encompassing both linkage of disparate domestic systems and elderly care. The results of the demonstrations are being incorporated into real-world applications. The Organization for the Advancement of Structured Information Standards globally adopted the service-oriented ecosystem concept as the Devices Profile for Web Services (DPWS) standard in June 2009. Although the intent of DPWS bears a similarity to the universal plug-and-play standard, DPWS facilitates dynamic discovery and is fully calibrated with Web Services technology, permitting seamless integration of device-provided services in enterprise-wide applications.
