Abstract

A system and method for data communication in a computational network is disclosed. The computational network includes a server computational device and a client computational device. The server computational device stores one or more container data objects, and a container data object includes a reference to multiple external data objects. The client computational device retrieves a container data object from the server computational device. If the container data object includes a reference to multiple external data objects, the client computational device sends a request to the server computational device. The server computational device provides a response including the multiple external data objects.
