F-logic

F-logic

F-logic (frame logic) is a knowledge representation- and ontology language.It accounts in a declarative fashion for structural aspects of object-oriented and frame-based languages.Features include, among others, object identity, complex objects, inheritance, polymorphism, query methods, encapsulation. F-logic stands in the same relationship to object-oriented programming as classical predicate calculus stands to relational database programming.
