• A template inheritance system like the concept of object-oriented programming.
• Caching framework that can use a wide variety of cache types.
• An internal dispatch system that allows parts of the application to communicate with each other via predefined signals.
• Internationalization policy, including translating Django’s own elements into different languages
• Django Model is a serialization system that can create and read XML and/or JSON representations of events.
• A system that extends the capabilities of the template engine.
• Good Interface to Python’s built-in unit testing framework.
