This data enables and supports research in areas such as software engineering, open source phenomena, social network analysis, data mining, and project management. This newly-formed database containing Concurrent Versions System (CVS) and Subversion (SVN) metadata offers new research opportunities for large-scale OSS development analysis. The CVS and SVN data is juxtaposed with the SourceForge.net Research Data Archive [5] for the purpose of performing more powerful and interesting queries. We also present an initial statistical analysis of some of the most active projects. %B IFIP Advances in Information and Communication Technology Open Source Software: New Horizons (OSS 2010) %I Springer Berlin Heidelberg %C Berlin, Heidelberg %V 319 %P 413 - 418 %@ 978-3-642-13244-5 %R 10.1007/978-3-642-13244-5_40
