CODES: Supporting the development process in a publish/subscribe system

This paper presents CODES (COsmic embedded DEvice Specifications) which allows to describe the properties of smart components. A component is a small autonomous device that encapsulates hardware, software and possibly mechanical parts. The interaction model for the components is based on a publisher/subscriber scheme in which well defined information objects - events - are produced and consumed. CODES provides a description for the smart components in the system related to the events which they produce and consume. Additionally, CODES is exploited by a set of an appropriate tools supporting the system developer with respect to different tasks: (1) CODES allows to keep the specification in compliance with the documentation and code; (2) CODES generates code skeletons to ease the programming task; and (3) CODES facilitates the integration of components in a larger system in which multiple components cooperate
