Time in the domain entities access architecture

Domain Entities Access is an architecture that enables the realization of platforms supporting responsive environments in the interaction with instrumented physical environments through the observation and the control of meaningful domain entities. This results in an environment model that abstracts from any technological details. Domain entities are characterized by a set of pairs property-value. The value of a property is the last inferred one without any information with respect to when the data used in the inference have been acquired. Thus, the status of domain entities lacks of timeliness. The architecture has been revised so that end-user applications can rely on both inspection and control mechanisms whose results are driven by time. The new implementation of the framework have been validated in a real simplified scenario.
