Detailed Description

Data provider interface definition.

The data provider interface allows to:

Define lists of items to be loaded automatically when a new root node is assigned to the data store.
Register objects from the data store. Once objects are registered with the data store the client gives up ownership.
Unregister objects from the data store. Unregistering an object means to actually delete all entries hanging below, not the object itself - since the client claims back ownership. Note that this is a very delicate operation - any reference to the object will be invalid. Even worse: invalid references cannot be detected.
Retrieve objects to the data store. Depending ont he availibility of the requested object in the data store the represented object will be loaded if possible.
Find objects beeing present in the store without actually creating the representation if the object is not present.
Create 'soft' links between objects in the transient store.
Request object updates.

Removed call to update registry entry state in the data service
