Open-system Environment Reference Model

Open-system Environment Reference Model

Open-system environment (OSE) reference model (RM) or OSE reference model (OSE/RM) was in the 1990s one of the first reference models for enterprise architecture. It provides a framework for describing open system concepts and defining a lexicon of terms, that can be agreed upon generally by all interested parties.

This reference model was meant to be an environment model based upon the POSIX architecture for open systems. It turned out to be a basic building block of several technical reference models and technical architecture. It 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.

In 1996 this reference model was standardized in the ISO/IEC TR 14252 titled "Information technology -- Guide to the POSIX Open System Environment (OSE)".

Famous quotes containing the words environment, reference and/or model:

    “If the Revolution has the right to destroy bridges and art monuments whenever necessary, it will stop still less from laying its hand on any tendency in art which, no matter how great its achievement in form, threatens to disintegrate the revolutionary environment or to arouse the internal forces of the Revolution, that is, the proletariat, the peasantry and the intelligentsia, to a hostile opposition to one another. Our standard is, clearly, political, imperative and intolerant.”
    —Leon Trotsky (1879–1940)

    “I am more and more convinced that, with reference to any public question, it is more important to know what the country thinks of it than what the city thinks. The city does not think much.”
    —Henry David Thoreau (1817–1862)

    “... if we look around us in social life and note down who are the faithful wives, the most patient and careful mothers, the most exemplary housekeepers, the model sisters, the wisest philanthropists, and the women of the most social influence, we will have to admit that most frequently they are women of cultivated minds, without which even warm hearts and good intentions are but partial influences.”
    —Mrs. H. O. Ward (1824–1899)
