Abstract: A method and system for maintaining the integrity of links in a computer network. The method and system is realized in a link tracking service including a local link tracking service, preferably running on all of the computers within the network, and a centralized link tracking server, preferably running on a network server. The local link tracking service manages the link tracking activities for the machine on which it resides. These activities include searching for link sources and tracking link source moves. The centralized link tracking service is provided to cooperate with the local link tracking services and, more particularly, for recording link source file movements as reported to it by the local link tracking services. The recorded information is available to be used by the local link tracking services should the local link tracking services need assistance in finding a link source that has been moved.

Abstract: An object based computer system has viewers which may be directed around the object world of the system between semantic objects. The system includes a sequence object that has a path list specifying a path around a sequence of semantic objects of system. Each viewer can be linked to the sequence object to access the path list held by the latter, thereby enabling the viewer to follow the corresponding sequence of semantic objects, viewing each in turn.
