              draft-ietf-supa-generic-policy-data-model-02

Abstract 

   This document defines two YANG policy data modules. The first is a
   generic policy model that is meant to be extended on an application-
   specific basis. The second is an exemplary extension of the first
   generic policy model, and defines rules as event-condition-action
   policies. Both models are independent of the level of abstraction of
   the content and meaning of a policy.

1.  Overview

   This document defines two YANG [RFC6020] [RFC6991] policy data
   models. The first is a generic policy model that is meant to be
   extended on an application-specific basis. It is derived from the
   Generic Policy Information Model (GPIM) defined in [1]. The second
   is an exemplary extension of the first (generic policy) model, and
   defines policy rules as event-condition-action tuples. Both models
   are independent of the level of abstraction of the content and
   meaning of a policy.

   The GPIM defines a common framework as a set of model elements
   (e.g., classes, attributes, and relationships) that specify a
   common set of policy management concepts that are independent of the
   type of policy (e.g., imperative, procedural, declarative, or
   otherwise). The first YANG data model is a translation of the GPIM
