Overview

Imperius (Simple Policy Language) or SPL - Is a simple standards based object-oriented policy language that allows expression of management policies using condition-action rules. Imperius provides an extensible set of over 100 operations for expressing conditions and actions.

Imperius is a generalization of the CIM-SPL language. Conversely, CIM-SPL can be thought of as Imperius with CIM binding. Imperius can be extended to create similar bindings for other environments. JavaSPL (Imperius with Java binding) is another such example.
