Abstract

A multimedia work stored on a CD-ROM is repurposed at run time to include changes and additions to the original work. Files required for repurposing the multimedia work are distributed on a floppy disk or CD-ROM for installation on the user's hard drive (16) prior to execution of the multimedia work on a personal computer (10). A run-time version of an authoring program employs one of the files for repurposing that includes references to objects/pages used in the repurposed multimedia work. Since objects communicate with the run-time authoring program through a node (89) and a filter (88), changes to the interaction between objects and the system are readily implemented by replacing the previous filter with a new filter. However, a filter is not required if the repurposing only replaces one object that was in the original work with a different object having the same label. Furthermore, because the objects and pages used in the multimedia work are not 'hard wired' in a compiled executable file that is implemented when the work is played, late binding of the objects and other elements permits seamless modification of the work at run time.
