Abstract: Managing the status of documents in a distributed storage system is disclosed. Upon determining that a first version exists and a second version having a predecessor version identifier exists, the predecessor version identifier is used to determine that the second version is related to the first version. Based upon the existence of the related second version, the status of the first version is updated.

Abstract: A graphical figure is defined. A library of simple tasks is created using trial stimulus/response combinations. A hill climbing algorithm is employed to find a stimulus/response combination that accomplishes an optimum result for each task. An animation editor facilitates the creation of composite animated sequences by causing the retrieving and displaying of a first simple task, controlling the length of time the first simple task is displayed and by causing the retrieving and displaying of additional simple tasks and controlling the length of time the additional simple tasks are displayed.
