In a distributed computing system having a network of computers linked for accessing objects distributed among said computers, some of said computers executing object access software enabling interested parties to request access to said objects for display of accessed ones of said objects, a computer-implemented method of operating at least one of said computers for automatically notifying said interested parties when objects of interest are changed, said computer-implemented method comprising the steps of:

  • a) accepting from said interested parties specifications of the objects of interest;

    b) maintaining in memory a list of the interested parties interested in each of the objects of interest;

    c) detecting occurrence of changes in the objects of interest, and in response to detecting the occurrence of a change in an object of interest, determining whether an update notification would then be desirable for each interested party in the list of interested parties interested in the object of interest in which the occurrence of change is detected; and

    d) upon determining that an update notification would then be desirable for one of the interested parties in response to detecting the occurrence of change in one of said objects of interest, notifying said one of the interested parties of the occurrence of change in said one of said objects of interest for display of said one of said objects of interest.
