Geometry (OWL Class)
Geometry is the root class of the hierarchy. The instantiable subclasses of Geometry are restricted to 0, 1 and 2-dimensional geometric objects that exist in 2, 3 or 4-dimensional coordinate space (R2, R3 or R4). Geometry values in R2 have points with coordinate values for x and y. Geometry values in R3 have points with coordinate values for x, y and z or for x, y and m. Geometry values in R4 have points with coordinate values for x, y, z and m. The interpretation of the coordinates is subject to the coordinate reference systems associated to the point. All coordinates within a geometry object should be in the same coordinate reference systems. Each coordinate shall be unambiguously associated to a coordinate reference system either directly or through its containing geometry. The z coordinate of a point is typically, but not necessarily, represents altitude or elevation. The m coordinate represents a measurement. All Geometry classes described in this specification are defined so that instances of Geometry are topologically closed, i.e. all represented geometries include their boundary as point sets. This does not affect their representation, and open version of the same classes may be used in other circumstances, such as topological representations.

Point (OWL Class)
A Point is a 0-dimensional geometric object and represents a single location in coordinate space. A Point has an x-coordinate value, a y-coordinate value. If called for by the associated Spatial Reference System, it may also have coordinate values for z and m. The boundary of a Point is the empty set.

Qualitative Description (OWL Class)
A Qualitative Description is used in situations when the Episode cannot be described by numeric values. This is also a point of extension of the ontology as other ontologies can be plugged here for extending it. For instance, one can define values such as "slow", "medium", or "fast" for speed episodes.
Definition
The URI of this class is http://purl.org/net/step#QualitativeDescription
| This class is a sub class of | Semantic Description |
Quantitative Value (OWL Class)
The value associated to the Episode. For instance, integer, decimal values. It is also associated with an Unit.
Definition
The URI of this class is http://purl.org/net/step#QuantitativeValue
| This class is a sub class of | Semantic Description |
Raw Trajectory (OWL Class)
Represent the raw data from trajectories. As there's no official support for ensuring sequential ordering of tuples, we advise putting sequential numbers into the URLs of fixes to be able to retrieve the spatial footprint of the trajectory. Another solution is querying using an ORDER BY statement that sorts by the time:Interval of each Fix that composes the RawTrajectory.
