|Name=Trajectory
|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.
|Domain=General, Earth Science or Geoscience, 
|CompetencyQuestion=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,
|ContentODPDescription=This pattern is reengineered from [Hu, et al., COSIT 2013] with changes as described in the intent of the pattern.

|Consequences=Unlike the original version of Semantic Trajectory, this pattern omits the hook to the data source for fixes (which was a subclass of ssn:Device) because instead of location/geo-coordinate, the notion of place is employed to capture the spatial extent. Nevertheless, it should be relatively straightforward to extend this version if the user wishes to attach data source information to the fixes.
|Scenario=Mike's trip to the GeoVoCamp 2012 from his home integrating data from GPS device, vehicle information, and personal information.A toucan flies through the air as recorded by researchers in the MoveBank.The 1990 World Chess Championship event that was held in two locations at two different times.
