The present document specifies and formalizes SmartBAN unified data representation formats (including in particular sensor/actuator elay/coordinator/Hub descriptions and sensed/measured data)@ semantic open data model and corresponding ontology. The present document is applicable to a BAN and/or a Smart BAN comprising wearable sensors/actuators devices@ a relay/coordinator device and a Hub. The relay/Coordinator and the Hub functionalities may be handled by a single device or by two distinct devices. The present document does not yet address the specification and the formalization of the SmartBAN service ontology and associated enablers. This will be addressed in the future release of the present document.
