This paper presents the ObjVlisp model designed to experiment and synthesize the expanding activities of the Object Oriented world. The goal is to specify a minimal kernel whose semantic is perfectly uniform, then to modelize other Object semantics by extending this concentrate kernel.\\ We propose a unification of the metaclass, class and object concepts which allows an optimal uniformity. This unification is obtained as a reflexive definition of the language. We rapidly describe some ObjVlisp variations establishing the malleability of the system.\\ The kernel is built on a portable virtual machine defined as a set of Lisp primitives which preserve the Lisp evaluator and maintain the spirit of dynamic (or lexical) scoping.
