'''Open-system environment (OSE) reference model (RM)''' or ''OSE reference model'' (OSE/RM) was in the 1990s one of the first [[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"/>

Basically, the open-system environment model is a basic building block of several technical reference models and technical architecture. The open-system environment (OSE) forms 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.
