2020-06-05 https://saref.etsi.org/saref4city/ s4city This ontology extends the SAREF ontology for the Smart City domain. This work has been developed in the context of the STF 534 (https://portal.etsi.org/STF/STFs/STFHomePages/STF534.aspx), which was established with the goal to create three SAREF extensions, one of them for the Smart City domain. v1.1.2 Information about changes compared to version 1.1.1: - Updated namespaces for compatibility with SAREF v3. SAREF extension for Smart City 2020-06-05 Event Temporary and scheduled event, like a festival or competition. (Definition taken from Wikidata) District A district is a type of administrative division that, in some countries, is managed by local government. Across the world, areas known as "districts" vary greatly in size, spanning regions or counties, several municipalities, subdivisions of municipalities, school district, or political district. (https://en.wikipedia.org/wiki/District) Public Service This class represents the service itself. A public service is the capacity to carry out a procedure and exists whether it is used or not. It is a set of deeds and acts performed by or on behalf of a public agency for the benefit of a citizen, a business or another public agency. 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. Anything that can be sensed, measured or controlled in households, common public buildings or offices. We propose here a list of properties that are relevant for the purpose of SAREF, but this list can be extended. An aspect of an entity that can be observable by a sensor. Property Public service Public service is a service which is provided by government either directly (through the public sector) or by financing provision of services. (Definition taken from Wikipedia) Country A country is a region that is identified as a distinct national entity in political geography. (https://en.wikipedia.org/wiki/Country) Public administration Public leadership of public affairs directly responsible for executive action. (Definition taken from wikidata) Temporal entity A temporal interval or instant. SpatialObject The class spatial-object represents everything that can have a spatial representation. It is superclass of feature and geometry. Time interval A temporal entity with an extent or duration Organization Unit of measure 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. Feature This class represents the top-level feature type. This class is equivalent to GFI_Feature defined in ISO 19156:2011, and it is superclass of all feature types. Actuator A device responsible for moving or controlling a mechanism or system Person Geometry The class represents the top-level geometry type. This class is equivalent to the UML class GM_Object defined in ISO 19107, and it is superclass of all geometry types. City object Generic class for describing city objects. Agent An agent making an action in the context of a city. An agent could be a person, software, etc. Instant A temporal entity with zero extent or duration 1 A Key Performance Indicator assessment represents the assessment of a KPI calculated by a given agent in a given time. Key performance indicator assessment Administrative area An administrative division, unit, entity, area or region, also referred to as a subnational entity, constituent unit, or country subdivision, is a portion of a country or other region delineated for the purpose of administration. (https://en.wikipedia.org/wiki/Administrative_division) 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 a start and stop function. Devices can be structured in categories (subclasses) that reflect the different domain in which a device is used, e.g., smart appliances domain (subclass FunctionRelated) vs. building domain (subclass BuildingRelated) vs. smart grid domain (subclass EnergyRelated). New categories can be defined,if needed, to reflect other differences, for example different points of view, such as the point of view of the device's user vs. the point of view of the device's manufacturer. We propose a list of devices that are relevant for the purpose of SAREF, but this list can be extended. Neighbourhood A neighbourhood (British English), or neighborhood (American English; see spelling differences), is a geographically localised community within a larger city, town, suburb or rural area. (https://en.wikipedia.org/wiki/Neighbourhood) 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. Measurement 1 City A city is a large human settlement. A city is distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status, which may be conferred by a central authority. (https://en.wikipedia.org/wiki/City) Agent Key Performance Indicator A Key Performance Indicator (KPI) is a type of performance measurement. KPIs evaluate the success of an organization or of a particular activity in which it engages. (Definition taken from FIWARE) 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), lat(P2, LAT), long(P2, LONG), alt(P2, ALT). sameThing(P1, P2) :- type(P1, Point), type(P2, Point), spaciallyIntersects(P1, P2). Facility A place, amenity, or piece of equipment provided for a particular purpose. (Definition taken from https://en.oxforddictionaries.com/definition/facility) controls property controls property location 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 . is measured in is subevent of is subevent of quantifies KPI quantifies KPI has calculation period has calculation period has geometry A spatial representation for a given feature. measures property contains Exists if the subject SpatialObject spatially contains the object SpatialObject.
