Themis is a lightweight, extensible authorization system, providing a explicit and strong type way of defining and demanding permissions. The main idea behind Themis is to allow a few dimensions of configuration, with no impact on your domain model (no interface to implement in your domain model). The configuration is code only (there is none xml file needed) and created with strong typed lambda expressions, hence any refactoring touching your model should work also with authorizations.
