Duality of object and material

Source: PMDco  ·  Published by: materialdigital.github.io  ·  Category: structural  ·  Domain: materials

Represents how an object and a portion of matter are the same material entity seen two ways: as material (steel) it bears chemical composition; as object (ingot) it bears mass. Distinguishes extensive qualities, which scale with the size of the object, from intensive qualities, which are independent of portion size.

What it answers

  • Which material is this object made of? Which qualities does an entity bear as a portion of matter (chemical composition) versus as an object (mass)? Which of an entity's qualities scale with its size and which do not?

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 11 classes, 2 properties, 75 axioms
Brings in nothing - it stands on its own
Reasoning HermiT finds this pattern consistent, with no unsatisfiable class, and its worked example consistent with the pattern.

Its IRI is https://ontoboard.org/patterns/pmdco-duality-object-material.owl - a name rather than an address: nothing answers there, so the download link above is the file.

Check it yourself: the published pattern  ·  an archived copy.

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 13 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.
