<p>Data format: CSV</p> <p>Separator character: '#'</p> <p><strong>This dataset contains 1151 commits manually labeled with maintenance activities ("c" for corrective, "p" for perfective, "a" for adaptive)</strong> according to the definition by Mockus et al. in  <em>"Mockus, A. and Votta, L.G., 2000, October.
