General description

Name: Trajectory
Submitted by: AdilaKrisnadhi
Also Known As:
Intent: The pattern provides a model of trajectory, which is understood as a sequence of spatiotemporal points. The model generalizing the Semantic Trajectory pattern from [Hu, et al., COSIT 2013] by employing the notion of place, instead of location/geo-coordinate, to represent the spatial extent of the trajectory. This pattern is suitable for a variety of trajectory datasets and easily extendible by by aligning to or matching with existing trajectory ontologies, foundational ontologies, or other domain specific vocabularies.
Domains:

General, Earth Science or Geoscience

Competency Questions:
  • Show the birds which stop at x and y
  • Show the birds which move at a ground speed of 0.4 m/s
  • Show the trajectories of rivers which cross national parks
  • Where are the ports at which the oceanographic cruise A3221 stopped after leaving Woods Hole?
  • List the places and times that represent the spatiotemporal extent of the 1990 World Chess Championship event
Solution description: This pattern is reengineered from [Hu, et al., COSIT 2013] with changes as described in the intent of the pattern.

Elements

The Trajectory Content OP locally defines the following ontology elements:

ObjectProperty atPlace (owl:ObjectProperty) Connects anything (including fixes in this pattern) to Place.
atPlace page
ObjectProperty atTime (owl:ObjectProperty) Connects anything (including fixes in this pattern) to TimeEntity
atTime page
ObjectProperty endsAt (owl:ObjectProperty) Connects a segment to the fix it ends at.
endsAt page
ObjectProperty hasAttribute (owl:ObjectProperty) Connects a fix or a segment to an additional information as represented by an instance of Attribute.
hasAttribute page
ObjectProperty hasFix (owl:ObjectProperty) Relating the trajectory to each of its fixes.
hasFix page
ObjectProperty hasSegment (owl:ObjectProperty) Relating the trajectory to each of its segments.
hasSegment page
ObjectProperty hasTrajectory (owl:ObjectProperty) Anything that has a trajectory can use this property to connect it to the trajectory instance.
hasTrajectory page
ObjectProperty nextFix (owl:ObjectProperty) Relates one fix to the immediately following fix in the sequence.
nextFix page
ObjectProperty startsFrom (owl:ObjectProperty) Connects a segment to the fix it starts from.
startsFrom page
ObjectProperty traversedBy (owl:ObjectProperty) Connect a segment to the moving object that traverses it.
traversedBy page
Class Attribute (owl:Class) Captures additional information that enriches some fix or segment.
Attribute page
Class EndingFix (owl:Class) The last fix in a particular sequence of fixes.
EndingFix page
Class Fix (owl:Class) Describes a fix, which is an adorned spatiotemporal point. A sequence of fixes form the trajectory.
Fix page
Class MovingObject (owl:Class) This is the hook to an ontology/pattern that describes the moving object, if any, which moves along the trajectory.
MovingObject page
Class Place (owl:Class) This is the hook to other pattern/ontology that describes the notion of place, which is more general than just a location/geo-coordinate.
Place page
Class Segment (owl:Class) The Segment class captures the "connection" between two consecutive fixes. That is, a segment starts from a fix and ends at another fix. If the pattern is used to model the trajectory of some moving object, each segment is traversed by that moving object. Additional information about a segment can be attached as attributes.
Segment page
Class StartingFix (owl:Class) The first fix in a particular sequence of fixes.
StartingFix page
Class TimeEntity (owl:Class) The hook to class/pattern/ontology that models time, this class provides the temporal extent of the trajectory. One example of time model is the W3C Time Ontology.
TimeEntity page
Class Trajectory (owl:Class) Represents the notion of trajectory, this is the main class that can be hooked with other patterns that use the Trajectory pattern. Trajectory in this model is understood as a sequence of fixes connected by segments. There is exactly one starting fix and exactly one ending fix. Each fix has a temporal extent and a place (which is more general than just a location).
