Ontology for weather phenomena and exterior conditions Weather Ontology weat The relation between something and the point, or other geometrical thing in space, where it is. For example, the realtionship between a radio tower and a Point with a given lat and long. Or a relationship between a park and its outline as a closed arc of points, or a road and its location as a arc (a sequence of points). Clearly in practice there will be limit to the accuracy of any such statement, but one would expect an accuracy appropriate for the size of the object and uses such as mapping . http://www.w3.org/2003/01/geo/wgs84_pos# geo location Relation between an Actuation and the property of a FeatureOfInterest it is acting upon. http://www.w3.org/ns/sosa/ acts on property Relation between an Actuation and the property of a FeatureOfInterest it is acting upon.

A window actuator acts by changing the state between a frame and a window. The ability of the window to be opened and closed is its ActuatableProperty. 1 1 1 1 1 An Actuation carries out an (Actuation) Procedure to change the state of the world using an Actuator. Actuation An Actuation carries out an (Actuation) Procedure to change the state of the world using an Actuator. The activity of automatically closing a window if the temperature in a room drops below 20 degree Celsius. The activity is the Actuation and the device that closes the window is the Actuator. The Procedure is the rule, plan, or specification that defines the conditions that triggers the Actuation, here a drop in temperature.

Crushing a rock sample in a ball mill. Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be hosted by Platforms. http://www.w3.org/ns/sosa/ Sensor Device, agent (including humans), or software (simulation) involved in, or implementing, a Procedure. Sensors respond to a stimulus, e.g., a change in the environment, or input data composed from the results of prior Observations, and generate a Result. Sensors can be hosted by Platforms. Accelerometers, gyroscopes, barometers, magnetometers, and so forth are Sensors that are typically mounted on a modern smart phone (which acts as Platform). Other examples of sensors include the human eyes. A quality of an entity. An aspect of an entity that is intrinsic to and cannot exist without the entity. http://www.w3.org/ns/ssn/ Property A quality of an entity. An aspect of an entity that is intrinsic to and cannot exist without the entity. System is a unit of abstraction for pieces of infrastructure that implement Procedures. A System may have components, its subsystems, which are other systems. http://www.w3.org/ns/ssn/ System System is a unit of abstraction for pieces of infrastructure that implement Procedures. A System may have components, its subsystems, which are other systems. 1 1 1 Represents the measured value made over a property. It is also linked to the unit of measure in which the value is expressed and the timestamp of the measurement. https://w3id.org/saref# Measurement The unit of measure is a standard for measurement of a quantity, such as a Property. For example, Power is a property and Watt is a unit of power that represents a definite predetermined power: when we say 10 Watt, we actually mean 10 times the definite predetermined power called "watt". Our definition is based on the definition of unit of measure in the Ontology of units of Measure (OM). We propose here a list of some units of measure that are relevant for the purpose of the Smart Appliances ontology, but this list can be extended. https://w3id.org/saref# Unit of Measure 34 9.7
