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.
Apache Imperius 1.0.0 features include
- Based on the CIM-SPL DMTF preliminary standard
- Minimal prerequisites and simple installation facilitates easy embedding into a user's application
- Can be easily extended to interact with the user's environment
- Simple declarative object-oriented language
- Extensive set of built-in operators used while specifying conditions and actions
- String Operators
- Boolean Operators
- Numeric Operators
- DateTime Operators
- Collection Operators
- Ability to add custom operators
- Actions can be organized in a simple workflow
- Cascaded policy execution
