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. |
| MeasurementAttribute | An Attribute that indicates what about a particular object is being measured. This is most commonly used for LengthMeasures, where it would not otherwise be clear as to whether the measure applied to the objects width, height, diagonal etc. |
| RelationalAttribute | Any Attribute that an Entity has by virtue of a relationship that it bears to another Entity or set of Entities, e.g. SocialRoles and PositionalAttributes. |
