This talk gives a bird eye's view of the programming model of Apache OpenOffice (AOO) and LibreOffice (LO). It should help interested developers to get conceptually jump-started with developing AOO/LO applications. It also introduces and demonstrates a free and opensource tool of a student from WU that allows creating hyperlinked documentation for UNO objects a programmer has in hands, but also for UNO types supplying the fully qualified name. Using the dispatch interface any AOO/LO language can take advantage of this great and helpful functionality aimed at developers.
