Frameworks like Hibernate offer an abstraction of the database schemas and provide a facility to generate bindings between the application model and the database. The specification of the bindings is done either by a configuration file or directly in the source code by the use of Java annotation.

Aranuka picks up this concept to provide an easy way to map a Java domain model to a topic map. By annotating the model classes and persisting them via the Aranuka framework, the data can be stored in a topic map without the cumbersome work which needs to be done to achieve this directly via a Topic Maps engine. Aranuka encapsulates the necessary engine calls to any Topic Maps engine which implements the TMAPI2 interfaces.

Aranuka is also able to read an existing topic map and synchronise the data with the Java domain model. Therefore it can also be used as a stand-alone persistence layer.
