A hyper-media system includes a storage device for storing a hyper-media document. The system includes a plurality of application processing units (APU) for conducting individualized processing in reference to the hyper-media document in accordance with the individual program of the APUs. A common processing unit is also provided for conducting and managing the processing of common attributes of the hyper-media document, which attributes are common among all of the processing performed by the APUs. A procedure management unit allocates various kinds of procedures for the hyper-media document to the common processing unit and the APUs. Both the common processing unit and each of the plural APUs include navigation processing which includes the functions of node management, link management and navigation management execution. Navigation processing specific to individual APUs thus provides enhanced flexibility in processing and in permitting use of the contents of one APU by another APU.
