Fluid is an InternalAttribute of an Object that does not have a fixed shape and thus tends to flow or to conform to the shape of a container.
|
Instances | Abstract | Properties or qualities as distinguished from any particular embodiment of the properties/qualities in a physical medium. Instances of Abstract can be said to exist in the same sense as mathematical objects such as sets and relations, but they cannot exist at a particular place and time without some physical encoding or embodiment. |
| Attribute | Qualities which we cannot or choose not to reify into subclasses of. |
| Entity | The universal class of individuals. This is the root node of the ontology. |
| InternalAttribute | Any Attribute of an Entity that is an internal property of the Entity, e.g. its shape, its color, its fragility, etc. |
| PhysicalState | The physical state of an Object. There are three reified instances of this Class: Solid, Liquid, and Gas. Physical changes are not characterized by the transformation of one substance into another, but rather by the change of the form (physical states) of a given substance. For example, melting an iron nail yields a substance still called iron. |
