Sensor A device that detects and responds to events or changes in the physical environment such as light, motion, or temperature changes. A device that has category saref:Sensor and performs a saref:SensingFunction. An aspect of an entity that can be observable by a sensor. Property Compass direction The four cardinal directions or cardinal points are the directions of north, east, south, and west, commonly denoted by their initials: N, E, S, W. East and west are at right angles to north and south, with east being in the clockwise direction of rotation from north and west being directly opposite east. Intermediate points between the four cardinal directions form the points of the compass. (definition taken from https://en.wikipedia.org/wiki/Cardinal_direction) Physical object Any Object that has a proper space region. (Definition extracted from DUL ontology) TESS (Telescope Encoder and Sky Sensor) The Telescope Encoder and Sky Sensor (TESS) is a Sky Brightness and Cloud detector developed as a device for a remote observatory. A TESS can observe the light magnitude and other properties as ambient temperature and sky temperature. Communication protocol A protocol is an agreement between the communicating parties on how communication is to proceed. (Definition taken from "Tanenbaum, A. S. (2003). Computer networks, 4-th edition. ed: Prentice Hall.") Frequency unit Unit of measure for the quantity frequency. Period measurement Represents the measured value over a period property. It is also linked to the period unit of measure in which the value is expressed and the timestamp of the measurement. 1 Period An individual representing the property period. Light A light source, which may be a lantern, a street light, a floodlight, a signal lamp or any other device whose primary purpose is the generation of light. (Definition taken from http://wiki.openstreetmap.org/wiki/Proposed_features/Key:light_source#Description) 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. Unit of measure Communication interface 1 An interface defines which primitive operations and services the lower layer makes available to the upper one, when referring to network layers. (Definition adapted from "Tanenbaum, A. S. (2003). Computer networks, 4-th edition. ed: Prentice Hall.") Color Color of the emitted light. It might be indicated by named colors or using other type of color values like hexadecimal for RGB, color temperature, etc. Light point An spatial point from where a light is projected. It might belong to a lamppost. 1 1 A digital representation encapsulates a physical object accessible via Web services Digital representation Lamppost A tall pole with a light at the top. Light property An aspect of light that can be observable by a sensor. System A group of related hardware units or programs or both, especially when dedicated to a single application. (Definition taken from https://en.oxforddictionaries.com/definition/system) Actuator Device that can act over at least one property. Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes. Spatial thing Frequency measurement Represents the measured value made over a frequency property. It is also linked to the frequency unit of measure in which the value is expressed and the timestamp of the measurement. 1 Frequency An individual representing the property frequency. Geometry Represents the shape of the light emission. It might be instantiated by individuals like "spherical", "cylindrical", etc. even though it is open to more comples representation of geometries using other vocabularies. Photometer A photometer, generally, is an instrument that measures light intensity or optical properties of solutions or surfaces. Length unit Unit of measure for the quantity lenght. Device A tangible object designed to accomplish a particular task in households, common public buildings or offices. In order to accomplish this task, the device performs one or more functions. For example, a washing machine is designed to wash (task) and to accomplish this task it performs the start and stop function. A service is a representation of a function to a network that makes the function discoverable, registerable, remotely controllable by other devices in the network. A service can represent one or more functions. A Service is offered by a device that wants (a certain set of) its function(s) to be discoverable, registerable, remotely controllable by other devices in the network. A Service must specify the device that is offering the service, the function(s) to be represented, and the (input and output) parameters necessary to operate the service. Service 1 A thing made or adapted for a particular purpose, especially a piece of mechanical or electronic equipment. For example ‘a measuring device’ (definition taken from https://en.oxforddictionaries.com/definition/device). In this ontology it refers to the devices for environmental purposes. 1 Device 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. 1 Measurement Temporal unit A temporal unit of measure, which provides a scale factor for a time quantity. Height measurement Represents the measured value made over a height property. It is also linked to the height unit of measure in which the value is expressed and the timestamp of the measurement. 1 Height An individual representing the property height. Point A point, typically described using a coordinate system relative to Earth, such as WGS84. Uniquely identified by lat/long/alt. i.e. spaciallyIntersects(P1, P2) :- lat(P1, LAT), long(P1, LONG), alt(P1, ALT), at(P2, LAT), long(P2, LONG), alt(P2, ALT). sameThing(P1, P2) :- type(P1, Point), type(P2, Point), spaciallyIntersects(P1, P2). has light point A relation between a lamppost and its light points uses communication interface A relation between a system and the communication interface it uses. has color A relation between a light emitted and its color. location The relation between something and the point, or other geometrical thing in space, where it is.
