+h| Abstract
+| Since the 1970’s it has been acknowledged that a
+complex system can be broken into (a) its invariant functional
+parts (mechanism), and (b) the externalized choices for how the
+system should behave (policy). Policy-based management’s main
+objective is to separate and externalize the decisions required by a
+system from the mechanisms provided by the system, and provide
+a way to define and evaluate these decisions. A few decades later,
+we have today a plethora of different policy models and even more
+policy languages – plus tooling – offering policy-based solutions
+for virtually any use case and scenario. However, policy-based
+management as a standalone domain has never been evaluated
+in terms of which parts are variant / invariant, i.e. which parts
+of policy-based management can be domain-, model-, language-,
+usecase-independent. In this paper, we introduce and define a
+formal universal policy model that does exactly that. The result
+is a model that can be used to design, implement, and deploy
+immutable policy infrastructure (engine and executor) being able
+to execute (virtually) any policy model.
