'''Open-system environment (OSE) reference model (RM)''' or ''OSE reference model'' (OSE/RM) is a 1990 [[reference model]]s for [[enterprise architecture]]. It provides a [[software framework|framework]] for describing [[Open system (computing)|open system]] concepts and defining a lexicon of terms, that can be agreed upon generally by all interested parties.<ref name="Hun95"/>

This reference model is meant as environment model, complementary to the [[POSIX]] architecture for open systems. It offers an extensible framework that allows services, interfaces, protocols, and supporting data formats to be defined in terms of nonproprietary specifications that evolve through open (public), consensus-based forums.<ref>ACM Sigsoft (1993) 15th International Conference on Software Engineering, May 17-21, 1993''. p.349</ref> This reference model served in the 1990s as basic building block of several technical reference models and technical architecture.
