Class: PhysicalSubstance

name: PhysicalSubstance
description: An undifferentiated amount of physical material which, when subdivided,
  results in each part being indistinguishable in nature from the whole and from every
  other part.
notes:
- 'OWL subClassOf restrictions: ∃hasMagnitude.∃hasAspect=_Aspect_volume; ∃hasMagnitude.∃hasAspect=_Aspect_mass'
comments:
- This concept generally corresponds to mass nouns in English. By contrast, instances
  of gist:PhysicalIdentifiableItem, such as a computer, book, or car, are count nouns.
  Physical identifiable items are made up of physical substances; e.g., a cake is
  made up of butter, flour, and sugar; a ring is made of gold. If you divide a physical
  substance such as an amount of water into parts, you have different amounts of water
  otherwise indistinguishable from one another; if you divide a physical identifiable
  item such as a computer into parts, each part will be distinguishable from the original
  whole.
- An instance of this class has weight and takes up space. We mean the physical gold
  in a ring, not the concept of gold that shows up in the periodic table. The latter
  would be an instance of gist:KnowledgeConcept.
examples:
- value: An amount of water, penicillin, sand, or gold.
- value: 'Negative example: the concept of gold.'

    description: A statement about someone or something's attributes or characteristics.
    comments:
    - This property is used to describe instance data which is not part of the ontology.
      A definition and a description have different semantics. Use skos:definition
      for a statement of the meaning of a thing and gist:description to describe a
      thing's attributes, characteristics, or features.
    examples:
    - value: A person does not have a definition, but might be described as being
        six feet tall with brown hair and blue eyes; an ontology class or taxonomy
        term has a definition.
    - value: '''The Empire State Building is a 102-story Art Deco skyscraper in midtown
        Manhattan in New York City. It was designed by Shreve, Lamb & Harmon and built
        from 1930 to 1931.'''
