A class with identifier http://rds.posccaesar.org/ontology/lis14/rdl/Compound

MetadataThis section provides information about 'Compound' itself.

Source ontologyIndustrial Data Ontology
is primitivetrue
natural language definitionA physical object with a defined material composition.
primitive rationaleThe semantics of materials, of which compounds would be a specialisation, is beyond the scope of IDO.
usage noteRenamed class. Checked materially in OED.
This is an abstract concept, or hook, to allow sub-classes to be added as needed.
The class 'compound' serves as an ultimate "book-keeping" superclass for a taxonomy of material make-up. It has been found useful in managing classifications (of physical objects) according to material composition. It carries no distinguishing constraints, since any physical object will have material composition. The class 'compound' would perhaps better be named "physical object classified according to material composition".
For explicit meaning of a 'compound' subclass, such as "steel [object]", employ an RDL 'quality' class representing "material composition", with restrictions to a modelling construct representing steel.

alternative labelCompound
ExampleIndividual objects that have composition such as 316 stainless steel, reinforced concrete, carbon monoxide
scope noteNatural kinds are expressly not to be classified as 'compound'. The class 'compound' is only to be used to classify amounts of matter, with non-semantic auxiliaries used to refer to chemical composition. The semantics of natural kinds such as "helium", "steel", or "hydrocarbon" is out of scope for IDO.

ConstraintsThis section lists constraints that members of 'Compound' shall satisfy.
