  This paper proposes a software repository model together with associated
tooling and consists of several complex, open-source GUI driven applications
ready to be used in empirical software research. We start by providing the
rationale for our repository and criteria that guided us in searching for
suitable applications. We detail the model of the repository together with
associated artifacts and supportive tooling. We detail current applications in
the repository together with ways in which it can be further extended. Finally
we provide examples of how our repository facilitates research in software
visualization and testing.
