Datatype Properties

acts on dp

IRI http://signalkg.visualmodel.org/skg#actsOn
Description

A class of object/place than Action can be performed on/in (e.g., windows). Range should be owl:Class, but for OWL-DL conformance only xsd:anyURI constraint is specified.

Domain skg:Action c
Range xsd:anyURI

attenuated by dp

IRI http://signalkg.visualmodel.org/skg#attenuatedBy
Description

A class of object than attenuates a category of Signal (e.g., walls attenuate sound signals). Range should be owl:Class, but for OWL-DL conformance only xsd:anyURI constraint is specified.

Domain skg:Signal c
Range xsd:anyURI

end time dp

IRI http://signalkg.visualmodel.org/skg#endTime
Description

The time at which a ConcreteAction finishes

Domain skg:ConcreteAction c
Range xsd:dateTime

fov dp

IRI http://signalkg.visualmodel.org/skg#fov
Description

The field of view of a Sensor (in radians)

Domain sosa:Sensor
Range xsd:decimal

pr exists dp

IRI http://signalkg.visualmodel.org/skg#prExists
Description

The probability of the Entity being present (e.g., of an attacker)

Domain skg:Entity c
Range xsd:decimal

pr occurs dp

IRI http://signalkg.visualmodel.org/skg#prOccurs
Description

The probability of an Entity (if present) performing an Action (e.g., the probability that an attacker will chose to break in via the window rather than by some other method)

Domain skg:Action c
Range xsd:decimal

reliable distance dp

IRI http://signalkg.visualmodel.org/skg#reliableDistance
Description

Description

The time at which a ConcreteAction begins

Domain skg:ConcreteAction c
Range xsd:dateTime
