Trajectory Pattern¶
Source: ODP portal · Published by: w3id.org · Category: structural · Domain: games
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.
What it answers¶
- 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,
The pattern¶
The graph is the axioms the pattern asserts; nothing here is inferred. Drag to rearrange, scroll to zoom, and use the graph's own search box to find a term inside it.
Opens at level of detail 3: classes, individuals, properties and restrictions, without the literals. Raise it with the LOD control in the graph's own toolbar to see annotation values and anything a reasoner adds.
Should you use this one?¶
| Size | 9 classes, 10 properties, 93 axioms |
| Brings in | 1 imported ontology, so adopting it adopts that too |
| Reasoning | HermiT finds this pattern consistent, with no unsatisfiable class, and its worked example consistent with the pattern. |

Check it yourself: the published pattern · an archived copy · the ontology itself.
If a link does not open
ontologydesignpatterns.org, which publishes most of this library, does
not currently answer over HTTPS, and its wiki redirects submission pages
to its front page. The archived copy is there for exactly that reason.
The ontology files themselves are still served over plain HTTP.
Terms it declares¶
The 19 classes and properties this pattern models, as the recommender scores them. Annotation properties and built-ins are excluded, because an annotation property is not modelling.

An example of it in use¶
The pattern says what may be asserted; this says it. The graph below is a small set of individuals that instantiate the classes above and are connected by its properties, so the shape the pattern describes is visible as data rather than as a schema.
Import this pattern into your own ontology from inside Protégé: OntoBoard → Reuse → Pattern library…, which hands it to Import terms… and writes the term list, the module, the import and the catalog entry the way ODK expects. See Working with ODK.
