Abstract

The core ontology introduces concepts for the structural elements of VSS defined through the rule set in the specifications. Figure 1 gives an overview of those. The root node is the Vehicle itself. From there the structure is given through so-called Branches. They serve as sorting element for the leaf nodes and are not specified in the specification itself in greater details. The leaf nodes contain the semantic information of signals, which expext to describe and hold information, which changes in greater frequency and of attributes, which are more static. The core of the ontology defines this structure in an OWL ontology and serves as a basis for the defined signals of the standard catalogue and potential further development of the branches as more than structural information.

VSSo Core Structure

2.1 OWL Classes

2.1.1 VehicleProperty

Owl Class:vsso:VehicleProperty
Definition:

VehicleProperty - Central concept for defining a vehicle, either through a VehicleComponent structure or connected directly to the vehicle. Every VehicleProperty shall be instantiated with a vehiclePropertyValue. It is good practice to set the time when the value was updated through propertyValueUpdatedAt The VehicleProperty follows the concept of a ssn:Property

2.1.2 StaticVehicleProperty

Owl Class:vsso:StaticVehicleProperty
Definition:

StaticVehicleProperty - Follows the definition of an attribute in VSS. StaticVehicleProperty is meant to stay stable at least over the duration of an ignition cycle. If you expect more frequent updates, please consider DynamicVehicleProperty

Sub-class of:VehicleProperty
See also:https://covesa.github.io/vehicle_signal_specification/rule_set/data_entry/attributes/

2.1.3 Vehicle

Owl Class:vsso:Vehicle
Definition:

Vehicle - Core concept of the ontology. Collects VehicleComponents and VehicleProperties belonging to a vehicle

2.1.4 VehicleComponent

Owl Class:vsso:VehicleComponent
Definition:

VehicleComponent - First of all a sorting element for VehicleProperties, following on the definition of a branch. It is encouraged to use the concept for actual parts modeled as `VehicleComponent.

2.1.5 ActuatableVehicleProperty

Owl Class:vsso:ActuatableVehicleProperty
Definition:

ActuatableVehicleProperty - Follows the definition of an actuator in VSS. It is a DynamicVehicleProperty, which can be changed. Refers to sosa:ActuableProperty

Sub-class of:DynamicVehicleProperty
See also:ttps://covesa.github.io/vehicle_signal_specification/rule_set/data_entry/sensor_actuator/
See also:https://www.w3.org/TR/vocab-ssn/#SOSAActuatableProperty

2.1.6 ObservableVehicleProperty

Owl Class:vsso:ObservableVehicleProperty
Definition:

ObservableVehicleProperty - Follows the definition of an sensor in VSS. It is a DynamicVehicleProperty, which can be observed but not changed. Refers to sosa:ObservableProperty

Sub-class of:DynamicVehicleProperty
See also:https://covesa.github.io/vehicle_signal_specification/rule_set/data_entry/sensor_actuator/
See also:https://www.w3.org/TR/vocab-ssn/#SOSAObservableProperty

2.1.7 DynamicVehicleProperty

Owl Class:vsso:DynamicVehicleProperty
Definition:

DynamicVehicleProperty - In contrast to a StaticVehicleProperty, this property is expected to change frequently, even within an ignition cycle. Examples are the vehicle speed, location, etc.

Sub-class of:VehicleProperty

2.1.8 PositionInVehicle

Owl Class:vsso:PositionInVehicle
Definition:

PositionInVehicle - Frequently VehicleProperties and VehicleComponents will appear in several different positions in the vehicle. Typicle examples are windows, seats, etc. This concepts shall be used to define the different position of the vehicle. They can be named with the positionName property.
