Posnett et al. model commiter / project relationships in open source repositories as a bipartite graph and use metrics from ecology to analyze the graph. They analyze the role of expertise and focus in commiters’ acitivities on the quality of the software. This is a very recent and solid piece of software engineering literature, which is founded on ecological theoretical basis. However, the purpose is analytical rather than engineering, as is the case in DIVERSIFY.
