receiving a query from the first application for objects that are related to the first data object;

determining, based on identifying the first graph data relation object, that the second data object of the second type is related to the first data object; and

providing, in response to the query, at least an identifier of the second data object, to the first application, to enable the first application to interact with the second data object.
