Class of Entity | Abstract A Class of Entity is a Class of Element that classifies Entitys. Being a subtype of Entity, it is also an instance of itself. The Class of Entity class is equivalent to “at least first-order class.” Note: 1) SysFEAT is a higher-order ontology, so Class of Entity may have instances that are also Class of Entity (Class of Classes). 2) SysFEAT is also a non-well-founded and allows for self-referencing Class of Entity. |
