An information object transport system for enabling nodes to transmit objects a digital data processing system. Each node includes an object store for storing a plurality of objects, at least one of the objects including at least one external reference identifying another object. An information object transport arrangement responsive to receipt of a command identifying an object in the object store performs a packing operation to generate a message comprising the identified object and other objects identified by an external reference of the identified object. After generating a message, the node transmits it to another node in the digital data processing system. Upon receiving a message, an external references resolution portion selects an object in a message and iteratively processes external references in the selected object to identify other objects in the message. The external reference resolution portion enables the object storing portion to store objects identified thereby.

Information object transport system

A data structure format conversion system comprising a front end converter, a back end converter, and a converter executive. The front end converter converts a source data structure in a source format to data in an intermediate format. The back end converter converts the data in the intermediate format to a target data structure in a target format. Finally, a converter executive controls the front end converter and back end converter to effect a conversion from the source data structure in the source format to the target data structure in the target format, through the intermediate format.
