Frames exposes any Blueprints graph as a collection of interrelated domain objects. Frames makes heavy use of InvocationHandler, Proxy classes, and Annotations to allow a developer to frame a graph element (vertex or edge) in terms of a particular Java interface. With Frames, it is possible to ensure that data within a graph is respective of a schema represented as a collection of annotated Java interfaces.
