Abstract
Methods and apparatus, including computer program products, using placeholder objects in the communication of structures of data objects. A server can respond to a request for a complete structure of data objects with a partial structure that includes placeholder objects, each having a position in the partial structure, each representing content that is present in the complete structure but omitted in the partial structure. A client can accept the partial structure instead of the complete structure, can transmit a placeholder substitution request to the server identifying a placeholder object, and can receive in response to the request a further structure of data objects to replace the identified placeholder object.
