A ontology defining weather-related concepts and properties being relevant to smart home systems that provide predictive control.
Inverse property of hasWeatherPhenomenon.
Links a WeatherCondition to a WeatherPhenomenon. A WeatherPhenomenon can be associated with an arbitrary number of instances of WeatherCondition.
Associates a WeatherStateSource with a WeatherState, i.e. specifies where a WeatherState's data comes from. One WeatherState can only have one WeatherStateSource.
Associates a WeatherPhenomenon to its WeatherState. One WeatherPhenomenon can only belong to one WeatherState, but one WeatherState can have an arbitrary number of instances of WeatherPhenomenon.
Associates a WeatherState to a WeatherObservation. One WeatherState can only be associated with one WeatherObservation.
Specifies the priority of a WeatherState (a positive integer). The higher this value is compared to another WeatherState's priority, the more the WeatherState takes precedence over the other WeatherState.
A WeatherPhenomenon describing a temperature of more than 25 degrees Celsius.
A WeatherPhenomenon specifying atmospheric pressure using the hasPressure property (in hPa/mbar on MSL).
A WeatherPhenomenon describing a temperature of less than 20 degrees Celsius.
A WeatherPhenomenon describing a wind speed of less than 1 m/s.
A WeatherPhenomenon describing a cloud layer with cloud cover 0 (clear sky). NOTE: This class only specifies a single cloud layer. It does not make any statement about other cloud layers.
A WeatherPhenomenon giving information about a cloud layer. There are two properties: hasCloudCover gives the cloud cover of this layer in okta (an integer in the interval [0-9] where 0 is clear sky, 8 is overcast and 9 is unknown). hasCloudAltitude gives the altitude of that cloud layer. If there is more than one cloud layer, for each cloud layer another WeatherPhenomenon must be created and linked to the appropriate WeatherState.
A WeatherState describing the current weather.
A WeatherState about the current weather based on data retrieved from a (collection of) sensor(s), e.g. it is connected to an instance of SensorSource via the hasSource property.
A WeatherState about the current weather based on data retrieved from an internet service, e.g. it is connected to an instance of ServiceSource via the hasSource property.
A WeatherPhenomenon specifying the dew point. The actual value is specified in degrees Celsius using the hasDewPoint property.
A WeatherPhenomenon giving information about wind. There are two properties: hasWindDirection gives the cloud cover of this layer in degrees (an integer in the interval [0-359] where 0 is North, 90 is East etc.). hasWindSpeed is a float specifying wind speed in m/s.
A WeatherPhenomenon describing a humidity of less than 40 percent.
A WeatherState describing the weather in 12 hours.
A WeatherState describing the weather in 15 hours.

A WeatherPhenomenon describing the absence of precipitation, either because the probability for precipitation is 0 (specified by the property hasPrecipitationProbability) or because the amount of precipitation per hour is 0 (specified by the property hasPrecipitationValue) or both.
A WeatherPhenomenon describing an atmospheric pressure between 1008 hPa and 1018 hPa.

A WeatherPhenomenon describing an atmospheric pressure of more than 1028 hPa.
A WeatherPhenomenon describing an atmospheric pressure of less than 998 hPa.
A WeatherCondition is a simple description of the state of the weather. Currently there are: Cloud, Fog, LightCloud, PartlyCloud, Rain, Sleet, Snow, Sun, Thunder. Several instances of WeatherCondition can be associated with the same instance of WeatherPhenomenon using the hasCondition property. That way, it is possible to describe a thunderstorm that comes with rain.
A WeatherPhenomenon specifies information about the weather (temperature, humidity etc.) for a certain WeatherState. It is linked to the WeatherState using the belongsToState property. For specifying the weather information, there exist several data properties: hasTemperature, hasHumidity, hasDewPoint, hasWindSpeed, hasWindDirection, hasPrecipitationProbability, hasPrecipitationValue, hasPressure, hasCloudCover, hasCloudAltitude, hasSunRadiation and hasSunAngleNoon.
A WeatherObservation puts together all the information known at a certain time about both the current and the future weather at a certain location. Using the mandatory properties location a Point -- having latitude, longitude and altitude -- the location this WeatherObservation belongs to is specified. The property hasObservation time gives the time when the data has been collected. A WeatherObservation can have an arbitrary number of WeatherStates. Each of them gives some information about either the current state of the weather or the weather predicted for some time in the future.
WeatherStateSource represents a source of weather data, either from a (collection of) sensor(s) (sub-concept SensorSource) or from an internet service (ServiceSource). WeatherStateSource is connected to WeatherState via the hasSource/isSourceOf properties.
A WeatherState is a set of weather information (temperature, humidity etc.). It is assigned to exactly one WeatherObservation (properties belongsToWeatherObservation/hasWeatherState), has a priority (property hasPriority) and has a source (where the weather information comes from, properties hasSource/isSourceOf). The weather information itself (temperature, humidity etc.) is provided using instances of WeatherPhenomenon that are connected using the belongsToState/hasWeatherPhenomenon properties.
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.
Anything with spatial extent, i.e. size, shape, or position. e.g. people, places, bowling balls, as well as abstract areas like cubes.
A comma-separated representation of a latitude, longitude coordinate.
A TemporalEntity describes the temporal dimension of a WeatherState. This can either be a specific moment (an Instant that has a specific time) or a period of time (an Interval having a start time and an end time).

Revision 1.10 2003/01/11 18:56:49 danbri Removed datatype range from lat and long properties, since they would have required each occurance of the property to mention the datatype.

Feedback welcomed. Revision 1.6 2003/01/10 20:18:30 danbri Added CVS log comments into the RDF/XML as an rdfs:comment property of the vocabulary.
