EMF provides modeling capabilities that allow modeling data as objects and generating Java code representations of those models. EMF also includes features like notification, commands, and change recording that can be used to build rich model editing applications. These features include adapters for notification, command frameworks for undoable operations, and change recorders for tracking model changes. When combined, they provide a powerful set of tools for synchronizing models and user interfaces.
