New generic service interface concerning data storage.
Following the work legal constraints applied with data storage, I would like to propose a new generic service interface which should be implemented by any service storing resources. Basically, it offers 3 methods for (1) reporting information about data stored ; (2) dropping all data linked to a context and (3) deleting a specific resource. See WSDL+XSD attached.
In a first step, repositories (ie ResourceContainer) and search engines (ie Indexer) should expose such interface. Then all service that may store data should too so we could have a common data management board.
