Region Pattern

Source: ODP portal  ·  Published by: ontologydesignpatterns.org  ·  Category: structural  ·  Domain: general

To represent and reason on values of attributes of things, by explicitly talking about the dimensions ("regions") of the attributes, which include those values.

What it answers

  • What is the value for the attribute of that entity?,Which entities have a certain value on that parameter/attribute/feature?

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 2 classes, 3 properties, 36 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.

A situation it was written for. We can represent and reason on any kind of attributes, parameters, features, etc., which have a given set of values. With the new OWL2 support for custom and complex datatypes, this pattern should be confronted with possible enrichments, or may be restricted to OWL1. Anyway, since datatypes cannot overlap with classes even in OWL2, it remains useful for the cases where the domain must be kept homogeneous.

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 4 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.
