Platform Description

The Fedora 4 platform is a ground-up reimagining of the Fedora repository architecture. We've built atop mature products in the content repository space to allow us to rapidly iterate to build a robust, scalable, and durable system.

Fedora 4 introduces a number of new features and stuff:

• a different kind of  object model  that allows (and, even encourages) hierarchy
• "native" RDF expressions of object properties
• a RESTful REST API that is consistent and follow-your-nose
• integrated support for low-level fixity checks
• asynchronous, event-driven points of extensibility
