  Software developers explore and inspect software repository data to obtain
detailed information archived in the development history. However, developers
who are not acquainted with the development context suffer from delving into
the repositories with a handful of information; they have difficulty
discovering and expanding information fragments considering the topological and
sequential multi-dimensional structure of repositories. We introduce ExIF, an
interactive visualization for exploring information fragments in software
repositories. ExIF helps users discover new information fragments within
clusters or topological neighbors and identify revisions incorporating
user-collected fragments.
