]> 1.03 smart home ontology for weather phenomena and exterior conditions 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 . this property was known as "belongsToState" in prior versions of the ontology The instant at which a weather report is created Denotes the time a weather state has been observed or is forecasted for. links a weather report to the reporting source, either an internet weather service or a local weather sensor relation of weather states and a one-word description for the observed weather situation Relation between weather states and the phenomena that are observed or forecasted a specific weather state is reported for a location by a weather report. this property describes an interval that denotes the time in the future (offset) for which the weather is reported The WGS84 altitude of a SpatialThing (decimal meters above the local reference ellipsoid). altitude latitude The WGS84 latitude of a SpatialThing (decimal degrees). longitude The WGS84 longitude of a SpatialThing (decimal degrees) 10 Wind direction Wind direction represented in degrees 360.0 90.0 -90.0 -180.0 180.0 Wind speed wind speed in metres per second (m/s) point 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). A point, typically described using a coordinate system relative to Earth, such as WGS84. SpatialThing Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes. 25.0 0.0 the current air pollution represented as European Air Quality Index value. The index value is based on 3 pollutants of major concern in Europe: PM10, NO2, O3 and will be able to take into account to 3 additional pollutants (CO, PM2.5 and SO2) where data are also available. 1 0.0 atmospheric pressure in hectopascal (hPa) 0.0 20.0 1 10 1 clound cover in the unit "Okta" 0 0 0 1 The dewpoint temperature in degrees Celsius. It is the temperature at which the air can no longer hold all of its water vapor, and some of the water vapor must condense into liquid water. The dew point is always lower than (or equal to) the air temperature. this concept was known as "DewPoint" in prior versions of the ontology 25.0 -25.0 37.0 10 11 12 13 14 15 16 17 18 19 1 20 21 22 23 24 2 3 4 5 6 7 8 9 0 7.9 10.7 17.1 20.7 -25.0 0.0 3.4 5.4 30.0 4.0 75 100 500.0 this concept was known as "HighSolarRadiation" in prior versions of the ontology 1 represents the relative humidity of the air in percent 32.6 0.2 1.5 1.5 3.4 0.0 1.0 0.2 10.7 12 12 25 50 50.0 250.0 this concept was known as "LowSolarRadiation" in prior versions of the ontology 50 75 6 12 6 12 5.4 7.9 13.8 17.1 1.0 4.0 this concept was known as "MediumPrecipitation" in prior versions of the ontology 250.0 500.0 60.0 5 8 0.0 50.0 this concept was known as "NeglectibleSolarRadiation" in prior versions of the ontology 0 0.0 0.0 0.2 25.0 60.0 8 0 5 1 represents precipitation in millimetres 20.0 25.0 this class was known as "SensorSource" in prior versions of the ontology this class was known as "ServiceSource" in prior versions of the ontology 0 6 0 6 1 measurement of solar irrradiation at a specific location in Watts per square meter (W/m²) this concept was known as "SolarRadiation" in prior versions of the ontology 24.4 10.7 13.8 20.7 24.4 10.7 24.4 1 exterior temperature in degrees Celsius 9 100 0 25 28.4 32.6 One-word description of the observed weather condition different weather phenomena that may influence the current and forecasted weather state. 1 1 1 1 1 1 a weather report that can be retrieved through a local sensor (e.g. weather station integrated in the smart home) or a remote internet service. Further a time division has been realized to differentiate between current, short, mid and long term forecasts. For the smart home domain, a time window of 24 hours for weather forecasts has been seen as suitable with a 24 hours forecast being classified as long-term forecast Holds information about the origins of weather reports 1 1 1 1 1 1 1 1 1 1 Describes the actual weather reported through information from the weather source. 24.4 28.4 1 360.0 1 Unit of wind direction is degrees Unit of wind speed in metres per second (m/s). Wind direction and speed are represented as datatype properties"hasDirection" and "hasSpeed"
