Hibernate to model resource

[Sven Win]

Hallo.

Is there any "best-practise" on how to model resources, which consist of 
other resources as well? I read the book of Richardson&Ruby recently and 
wondered how I could map their idea of "fully connected resources" to a 
hibernate-domain-model.

Hibernate has it's annotations, so you can model the relations between 
objects. But when it comes to REST, you don't need a full objectgraph. 
How to solve this problem? By just getting an identifier of the entities 
the object contains and qrapping a String around that?

Thanks,
Sven Win
