This document presents work examining Open Source Software (OSS) project and developer networks, built from Concurrent Versions System (CVS) log data, from topological and temporal perspectives. Statistical analysis, visualizations, and comparison of two major OSS communities are presented. One aspect of this study is the nature of developer ties, how repeat ties affect long-term project popularity and development on SourceForge, as well as the distributions of various temporal measurements. Lastly, we examine evolutionary trends of the collaboration network. Network slices in yearly increments are analyzed to determine how centralities change from year to year, where new developers and projects join the network, and the change in modularity and number of communities in each network.
