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. |
| 分類方案 | A ClassificationScheme is a conceptual structure, an abstract arrangement of concepts and the relations that link them. |
| CodeMap | An instance of CodeMap is a ClassificationScheme that specifies correspondences (typically, one to one or one to many) between members of a set of tokens (typically, short alphanumeric SymbolicStrings) and other entities. In most cases, the other entities will be terms (logical constants) that denote SUMO concepts. |
| Entity | The universal class of individuals. This is the root node of the ontology. |
| Proposition | Propositions are Abstract entities that express a complete thought or a set of such thoughts. As an example, the formula '(instance Yojo Cat)' expresses the Proposition that the entity named Yojo is an element of the Class of Cats. Note that propositions are not restricted to the content expressed by individual sentences of a Language. They may encompass the content expressed by theories, books, and even whole libraries. It is important to distinguish Propositions from the ContentBearingObjects that express them. A Proposition is a piece of information, e.g. that the cat is on the mat, but a ContentBearingObject is an Object that represents this information. A Proposition is an abstraction that may have multiple representations: strings, sounds, icons, etc. For example, the Proposition that the cat is on the mat is represented here as a string of graphical characters displayed on a monitor and/or printed on paper, but it can be represented by a sequence of sounds or by some non-latin alphabet or by some cryptographic form. |
