This ontology defines:
Label: Fixed Duration Sum
IRI: https://w3id.org/seas/FixedDurationSum
Utility class to qualify the relation between a property and its sum over a time interval whose duration is fixed.
For example:
[] a seas:FixedDurationSum ; seas:summedProperty <fridge/1/consumptionPower> ; seas:sumProperty <fridge/1/consumption> ; seas:sumDuration "PT24H"^^xsd:duration .
means that at any time, the value of <fridge/1/consumption> is the sum of <fridge/1/consumptionPower> over the past day.
domain of: sumDuration
Label: Fixed Start Sum
IRI: https://w3id.org/seas/FixedStartSum
Utility class to qualify the relation between a property and its sum over a time interval whose start is fixed.
For example:
[] a seas:FixedStartSum ; seas:summedProperty <fridge/1/consumptionPower> ; seas:sumProperty <fridge/1/consumption> ; seas:sumStart "2014-02-24T00:00:00Z"^^xsd:dateTime .
means that at any time, the value of <fridge/1/consumption> is the sum of <fridge/1/consumptionPower> since February 24th 2014.
Label: Instantaneous Evaluation
IRI: https://w3id.org/seas/InstantaneousEvaluation
The class of evaluations that are relative to an instant
Label: Time Average Evaluation
IRI: https://w3id.org/seas/TimeAverageEvaluation
The given value is the average of the quantity over the temporal context.
Label: Time Constant Evaluation
IRI: https://w3id.org/seas/TimeConstantEvaluation
The given value is the value of the quantity at any instant of the temporal context.
Label: Time Interval Evaluation
IRI: https://w3id.org/seas/TimeIntervalEvaluation
The class of evaluations that are relative to a time interval
Label: Time Maximum Evaluation
IRI: https://w3id.org/seas/TimeMaximumEvaluation
The given value is the maximum of the quantity over the temporal context.
Label: Time Minimum Evaluation
IRI: https://w3id.org/seas/TimeMinimumEvaluation
The given value is the minimum of the quantity over the temporal context.
Label: Time Sum
IRI: https://w3id.org/seas/TimeSum
Utility class to qualify the relation between a property and its sum over a time interval. Two sub classes of seas:TimeSum enable to further describe the time interval over which the sum is computed: seas:FixedStartSum, and seas:FixedDurationSum.
domain of: sumProperty, summedProperty
Label: event frequency
IRI: https://w3id.org/seas/eventFrequency
Links a feature of interest to a frequency of the events during a temporal context. Functional sub properties of seas:eventFrequency define the semantics of the event.
sub property of: hasProperty
Label: event number
IRI: https://w3id.org/seas/eventNumber
Links a feature of interest to a number of events during a temporal context. Functional sub properties of seas:eventNumber define the semantics of the event.
For example, if a window was closed 5 times during last night:
seas:closingNumber a owl:ObjectProperty , owl:FunctionalProperty ;
rdfs:subPropertyOf seas:stateChangeNumber .
<window> seas:closingNumber <window/closingNumber> .
<window/closingNumber> seas:evaluation <window/closingNumber/evaluation/1> .
<window/closingNumber/evaluation/1> seas:evaluatedValue 5 ;
seas:hasTemporalContext [
time:hasBeginning [ time:asXSDDateTime "2016-09-25T23:00:00Z" ] ;
time:hasEnd [ time:asXSDDateTime "2016-09-26T07:00:00Z" ] ; ]
Label: state change frequency
IRI: https://w3id.org/seas/stateChangeFrequency
Links a feature of interest to the frequency of experienced property value changes during the considered temporal context. Functional sub properties of seas:stateChangeFrequency define the semantics of the property.
Label: state change number
IRI: https://w3id.org/seas/stateChangeNumber
Links a feature of interest to the number of changes the value of a property experienced during the considered temporal context. Functional sub properties of seas:stateDuration define the semantics of the property.
For example, if a window was opened and closed 5 times during last night:
seas:openCloseChangeNumber a owl:ObjectProperty , owl:FunctionalProperty ;
rdfs:subPropertyOf seas:stateChangeNumber .
<window> seas:openCloseChangeNumber <window/openCloseChangeNumber> .
<window/openCloseChangeNumber> seas:evaluation <window/openCloseChangeNumber/evaluation/1> .
<window/openCloseChangeNumber/evaluation/1> seas:evaluatedValue 5 ;
seas:hasTemporalContext [
time:hasBeginning [ time:asXSDDateTime "2016-09-25T23:00:00Z" ] ;
time:hasEnd [ time:asXSDDateTime "2016-09-26T07:00:00Z" ] ; ]
Label: state duration
IRI: https://w3id.org/seas/stateDuration
Links a feature of interest to the duration during which a property has a given state during the considered temporal context. Functional sub properties of seas:stateDuration define the semantics of the property and the state.
For example, if a window was open during 2 hours last night:
seas:openDuration a owl:ObjectProperty , owl:FunctionalProperty ;
rdfs:subPropertyOf seas:stateDuration .
<window> seas:openDuration <window/openDuration> .
<window/openDuration> seas:evaluation <window/openDuration/evaluation/1> .
<window/openDuration/evaluation/1> seas:evaluatedValue "PT2H"^^xsd:duration ;
seas:hasTemporalContext [
time:hasBeginning [ time:asXSDDateTime "2016-09-25T23:00:00Z" ] ;
time:hasEnd [ time:asXSDDateTime "2016-09-26T07:00:00Z" ] ; ]
Label: sum property
IRI: https://w3id.org/seas/sumProperty
Links a time sum to the property that is result of a sum over a time interval.
Label: summed property
IRI: https://w3id.org/seas/summedProperty
Links a time sum to the property that is summed over a time interval.
Label: time derivative
IRI: https://w3id.org/seas/timeDerivative
Links a time relative property to its time derivative property. For example,
<car/1/speed> seas:timeDerivative <car/1/acceleration> .
Means that <car/1/acceleration> is the time derivative of <car/1/speed>.
sub property of: derivesFrom
Label: sum duration
IRI: https://w3id.org/seas/sumDuration
Links a fixed duration sum to the duration of the floating time interval over which the sum is computed.
Label: sum start
IRI: https://w3id.org/seas/sumStart
Links a fixed start sum to the start of the time interval over which the sum is computed.
