  <http://purl.org/dc/elements/1.1/description> """SAN stands for Semantic Actuator Network. It is intended to describe Semantic Actuator Networks, as a counterpoint to SSN definition of Semantic Sensor Networks. An actuator is a physical device having an effect on the world (see Actuator for more information).

It is worth noticing that some concepts are imported from SSN, but not SSN as a whole. This is a design choice intended to separate as much as possible the definition on actuator from the definition of sensor, which are completely different concept that can be used independantly from each other.

This ontology is used as a ontological module in IoT-O ontology.""";
