Structural Aspects

Classes

Aggregate

Definition:

An aggregate thing is one where at least some of the parts of the whole remain somewhat distinct and removable from it.

Example:

1. A Car is an aggregate where components like wheels and engine can be removed and replaced.

OWL:

fnd:Aggregate a owl:Class ;
  rdfs:subClassOf fnd:StructuredThing ;
  owl:disjointWith fnd:Composite;
  skos:prefLabel "Aggregate"@en ;
  skos:definition "..."@en ;
  skos:example "..." .

Atomic

Definition:

An atomic thing has no parts that from which it was made, or into which it may be decomposed. Atomic things are disjoint with structured things.

OWL:

fnd:Atomic a owl:Class ;
  rdfs:subClassOf fnd:PhysicalThing ;
  owl:disjointWith StructuredThing ;
  skos:prefLabel "Atomic"@en ;
  skos:definition "..."@en .

Composite

Definition:

A composite thing is one where the parts, once included in the whole no longer have any distinction from the whole and may not be meaningfully removed from it.

Example:

1. An omelette is a composite, you cannot reconstitute the egg used as a part.

OWL:

fnd:Composite a owl:Class ;
  rdfs:subClassOf fnd:StructuredThing ;
  owl:disjointWith fnd:Aggregate ;
  skos:prefLabel "Composite"@en ;
  skos:definition "..."@en .

Dependent thing

Definition:

A thing whose existence depends on the existence of some other thing.

OWL:

fnd:DependentThing a owl:Class ;
  rdfs:subClassOf fnd:Thing ;
  owl:disjointWith fnd:IndependentThing ;
  skos:prefLabel "Dependent thing"@en ;
  skos:definition ""@en .

Independent thing

Definition:

A thing whose existence is not dependent on the existence of some other thing.

OWL:

fnd:IndependentThing a owl:Class ;
  rdfs:subClassOf fnd:Thing ;
  owl:disjointWith fnd:DependentThing ;
  skos:prefLabel "Independent thing"@en ;
  skos:definition "..."@en .

Part

Definition:

Some thing which acts as a component of a structured thing.

OWL:

fnd:Part a owl:Class ;
  rdfs:subClassOf fnd:Thing ;
  skos:prefLabel "Part"@en ;
  skos:definition "..."@en .

Physical thing

Definition:

A thing that has a physical form, it has mass and dimensions.

OWL:

fnd:PhysicalThing a owl:Class ;
  rdfs:subClassOf fnd:Referent ;
  skos:prefLabel "Physical thing"@en ;
  skos:definition ""@en .

Structured thing

Definition:

A thing that has some form of internal structure, it has parts whether it is a composite or aggregate thing.

OWL:

fnd:StructuredThing a owl:Class ;
  rdfs:subClassOf fnd:PhysicalThing ;
  owl:disjointWith fnd:Atomic ;
  skos:prefLabel "Structured thing"@en ;
  skos:definition ""@en .
