Thing

Description

Abstract Concept

An Entity is a distinct, identifiable Element that has a proper existence (living or non living). It is accessible by some referencing mechanism and can have Relations to other Entitys.

The Entity class is the powerinstance of Class of Entity: all subtypes of Entity are instances of Class of Entity.

Class Ordering of Entity: an Entity is either an Ordered Entity or a Mixed-Order Entity

Functional Domain: Reflexive Knowledge Graph

The Reflexive Knowledge Graph domain defines the top level constructs of Entitys, Relations, their multi-level classification and mereological relationships.

Relationship Table

Relationship	Cardinality	Target Entity	Source Entity	Description
PowerTyped by Class of Entity	[1..1]	Class of Entity	Entity
Typology	[*..0]	Class of Entity	Entity	Abstract Relationship A Typology is a Relation between an Entity and its categorical nature - the intrinsic properties or criteria that determine the Entity membership within a Class of Entity. Typology governs two distinct categorization mechanisms:- instance of Entity: assigning a Ordered Entity to a predefined Class of Entity based on shared characteristics (e.g., grouping by common traits).- SubTypeOfEntity: refining a Class of Entity into a subclass with narrower criteria (e.g., inheritance hierarchies or subtype relationships).While instance of Entity focuses on grouping Ordered Entitys into Class of Entitys, SubTypeOfEntity emphasizes hierarchical refinement of Class of Entityes themselves. Both mechanisms operate under the umbrella of typology, which formalizes how Ordered Entitys are systematically categorized.
Relation	[*..0]	Entity	Entity	Abstract Relationship A Relation is the reification of a Linkage of the Predication Substrate, as an Element that represents a directed connection between a source Entity and a target Entity.Relations are nested within their source Entity. (principle of locality).
Reference Relation	[*..0]	Entity	Entity	Abstract Relationship A Reference Relation is a Relation that points at a target Entity which is not in the Lexical Scope of its source Entity.
Existential Dependency	[1..1]	Entity	Entity	Abstract Relationship An Existential Dependency relationship is a Relation where the source Entitys existence depends on the existence of the target Entity.The cardinality of the set of targetted Entity is [1..1].
Existential Independence	[*..0]	Entity	Entity	Abstract Relationship An Existential Independence relation is a Relation that specifies that the existence of the source Entity doesnt depend on the existence of its target Entity.The cardinality of set of targetted Entity is [0..*].
instance of Entity	[*..0]	Class of Entity	Entity	Abstract Relationship instance of Entity is a Typology relationship that relates an Entity to a Class of Entity, as instance of this Class of Entity.
